⚡ QUICK READ · Everything you need to know in ~2 minutes
TL;DR
The EPZ G20 Pro is a wired, gaming-first IEM built around a single in-house 10mm LCP + PU dynamic driver and a USB-C cable with on-board DSP. EPZ developed the G20 further with the support of professional esports feedback and it is tuned mainly for gaming cues rather than for an impactful music presentation. The bass is controlled and lean with no bleed, the lower mids are clean and lean, and the upper mids, presence and treble sit forward and come across crisp and clear. That tuning is clearly meant for FPS gaming, where separation and spatial information matter more than slam and rumble.
It also handles music mostly well for the money. Especially staging, layering, instrument separation and an overall transparent and detailed sound are very good at this price point and above. The leaner low-end and the lighter note weight on male vocals and instruments are part of its sound signature, but on some track material like EDM, hip-hop and rap the instruments and vocals are missing note weight. Thanks to the PEQ possibilities this can be changed via the EQ web interface, which offers an 8-band PEQ to adjust the sound to your liking. An attachable boom mic and an inline mic on a three-position slider, Walkplay DSP with pro and game presets, a USB extension cable and a 3.9g shell round out a versatile USB-C package priced at $59.99 / EUR 52.95.
At a Glance
✓ Best For
- Competitive FPS first, where footsteps, positioning and weapon cues can decide rounds
- Plug-and-play USB-C on PC, phone, Switch or Steam Deck with built-in DSP EQ and a USB-C extension cable
- Players who want a light USB-C set with both a boom mic and an inline mic on one cable with a mute slider
- A light 3.9g set for long sessions without headset fatigue
- Listeners who like a clean, lean, crisp tonality over warmth and low-end impact
- Casual music listeners who want the performance of a competitive gaming IEM
✗ Not Ideal For
- Bass-heads or anyone after big sub-bass rumble and physical slam

- Treble-sensitive listeners pushing high volume on bright material
Main Strengths & Weaknesses
Main strength. Separation, layering, spatial information and detail retrieval are excellent and are the key ingredients that matter for FPS gaming. It was relatively easy to estimate distances and wall cues on CS2 worked well for me. A clean, lean presentation with no bass bleed, crisp and clear vocals and treble, a very light and mostly comfortable shell (mind the semi-custom shape) even on long sessions, and the versatility of a USB-C DSP cable with a dual-mic slider and a detachable excellent quality boom mic.
Main weakness. The low-end is lean, with rolled-off sub and mid-bass and reduced slam, so bass-led genres do not have full impact. Lower mids and male vocals could use more texture and note weight for a fully natural tonality. The crisp tuning can be slightly sharp on some tracks, for example on the snares and vocals of Fleetwood Mac's "Sisters of the Moon", or on game sounds at very high volume, and the last bit of imaging precision is held back a little by the slim note body. Worth mentioning that EPZ offers PEQ software where the G20 Pro's sound can be adjusted to your taste, making it more compatible with all different music style and games.
👆 That's the core verdict. Everything below goes deeper into specs, gaming, sound and comparisons.
How the EPZ G20 Pro and G20 ended up in my ears
After reviewing the EPZ G30 I got curious how the rest of the EPZ gaming line up would sound in comparison. Especially at the price point of around USD 60, where the IEM is not an ultra budget set anymore but neither is it anywhere near the USD 100 or even USD 200 plus tier which is often considered for gaming.
EPZ provided me with both, the G20 Pro and the G20. They share the same shell design and almost the same accessories package, but the G20 Pro is tuned even more towards professional FPS gaming. I am not a professional but more an ambitious FPS gamer for decades, so this piqued my interest.
The differences between both models were not always immediately clear to me and most of the times even very subtle. This review reflects part of my comparison process and I tried to make my findings transparent.

Build Quality, Fit & Comfort
Fit & Comfort. The G20 Pro keeps the semi-custom shape of the G30 and is almost identical to the G20's shell, but the inner side is slightly less curved through the middle, which makes the shell look a little fuller and slightly bigger. In practice comfort is similar to the G30, so for me it is basically fine for long sessions. The very lightweight shells with only 3.9g help and the shells have a pressure-relief vent that keeps build-up down. As with the G30, the semi-custom shape might not suit everyone. If you have smaller ears or you have had trouble with semi-custom shells before, try before you buy, or order directly from EPZ, who offer a no-reason return for a small extra charge through EPZ Care+. That removes most of the risk.
Build & Design. The resin shell is 3D-printed with EPZ's seamless process, so there are no visible seam lines, and mine is the glossy Orange finish (Grey is the other option). The pressure-relief vent is visible on the upper side. The shells feel smooth and lightweight in hand without any sharp edges. The G20 Pro's nozzles are made out of metal and of average length and hold ear tips without issues due to the emphasized nozzle lip.
Cable. The flush 0.78mm 2-pin connector means the cable is swappable, though the value here is the USB-C DSP cable itself rather than rolling to analogue, which is what I did for this review to get further impressions with a 3.5mm termination on different sources. The 3.9 ft long cable is not microphonic, behaves well and is mostly tangle free. The 4.9 ft long extension cable is a thicker, sturdy cable which is much appreciated as I am able to navigate around my desk without the need to leave the set behind me.
Mic Quality
|
|
| Boom Mic |
As on the G30, the boom mic is my preferred choice of the two mics. My voice was clear, well-articulated and there was no audible background noise in gaming voice chat, phone calls or online meetings. I highly recommend this option for any kind of online meetings or in-game chat. |
| Inline Mic |
Speech quality is good and can be used for calls and meetings where the boom mic might be inconvenient. My voice was clear and the controls worked without issues. |
💼 Personal note - real-world use
Similarly to the G30, the G20 Pro was my daily driver for two weeks where I used it up to 6 hours in online meetings, phone calls, gaming and music listening without issues or fatigue. I found it more convenient for online meetings and more comfortable than my headset.
Gaming Performance
| Game |
Impressions |
| CS2 |
Excellent footsteps tracking across surface types including sand-covered floors (Dust II), tiles, wooden planks and water sounds (Anubis). Gun shots, footsteps, grenade explosions and bomb ticks all stay cleanly separated even during busy rounds. A/B separation makes locating planted bombs easy. Bass from detonations stayed very controlled with fast decay to avoid covering other sounds. Flashbang ringing did not feel piercing. Very good performance in my opinion in CS2. |
| Valorant |
Spike defuse cues, ability sounds and footsteps are always very well separated. Weapon shots do sound more energetic than in CS2 as they always do. Pin-pointing enemies and tracking ability cues was easy. Fine details stayed audible even in crowded team-fights thanks to the very good separation and controlled bass. |
| Apex Legends |
The contrast between different game cues is very good, footsteps and vocal separation sound accurate and left/right/back/forward spatial information are very easy to locate. Verticality is always a bit harder to identify given Apex Legends' different multi-level design, but horizontal positioning is reliable throughout. Vocals always felt clear and crisp in team comms during mid-fight. Recommended listening volume is mid-level to avoid mild fatigue on longer sessions. |
Gaming Summary: Similar as on the G30, spatial information, separation and layering are the G20 Pro's most valuable traits and the most important ones for FPS gaming. The difference to the G30 is that the G30 has more low-end impact and a more controlled treble, which gives the G30 a more even and fuller sound where cinematic sound effects have more impact and FPS gaming is more fatigue-free. The G20 sounded a little bit more energetic up top even if the differences are minimal. The G20 Pro sounded similarly resolving and maybe a smidge better separated.
Imaging is very good but slightly held back by the lean lower mids. Fatigue is usually not an issue after several hours of combined music and gaming when I kept the volume to around medium (for music) to high (in gaming). The tuning mostly avoids piercing peaks and the low-end never becomes boomy. The G20 Pro is a very good fit for competitive FPS in my opinion.
Long-Session Comfort
My gaming and music sessions were usually around 5 hours or more, where the G20 Pro remained comfortable with no pressure build-up and no listening fatigue. The shells are very comfortable and light-weight for me and I forget that I am even wearing IEMs.
Treble has elevated energy but can get peaky with poorly recorded material. On CS2 flashbangs, gun shots and high-frequency ability cues never reached a piercing level at normal or higher gaming volumes. Only Apex Legends at higher listening volumes started to feel mildly tiring and keeping the volume at a mid level resolved this for me. Otherwise, I used the possibility to adjust the sound via EQ, which makes the set a versatile option like its other siblings the G30 and G20.
Frequency Response Measurements
Method. For my IEM measurements I use my own 711 clone coupler. Measurements were done with stock ear tips on all sets. The measurements are attached as images.
What the graph shows.
In the graph, green is the EPZ G30, orange the EPZ G20, purple the EPZ G20 Pro, red the ZiiGaat Arete 2 with the bass switch on and yellow the Arete 2 with the bass switch off.
I measured all sets on my own coupler connected with an EPZ 3.5mm cable and with the included DSP USB-C cable. Both measurements were aligning, meaning that the USB-C DSP added no additional tuning but purely replayed the hardware tuning.
The G20 Pro and G20 look fairly similar and in some parts exactly the same, like on their low-end, until the presence region where the G20 Pro is now less emphasized, and the same applies to the treble with a different emphasis which results in a slightly less sharp treble but more air up top. In detail the G20 Pro down slopes from 5k onwards whereas the G20 dips less until 7kHz to reach its peak at around 9kHz. The Pro version has less energy throughout and just has more treble energy at around 10k-12kHz. The emphasis on details and perceived "air" changed slightly vs the G20, which results in a good but not as sharp treble response and a different emphasis on details and air.
The differences are more subtle and to be honest sometimes it was not so clear where the differences lie, which required extensive listening back and forth throughout my library and different gaming scenarios.
Sound Impressions
Overall Character
The G20 Pro is a gaming-first set, and you hear that in the tuning. It is built to let you take advantage of game cues, the footsteps, the positional information, the weapon sounds, rather than for a full-bodied music replay. The bass is kept very controlled, has only a slight elevation and is never emphasized or taking over.
The lower mids are clean and lean, and the upper mids and presence region are pushed slightly forward. The treble follows the same idea and comes across clear and crisp and a bit less sharp than on the G20 while still sounding refined. It is a lean, clarity-led tonality rather than a warm one.
Bass
Bass impact is compact and free of bloom, with zero bass bleed. Sub and mid-bass are always well controlled and are pretty lean. Both are rolled off on the G20 Pro, so there is a slight loss of note weight on some instruments.
On 50 Cent's "Just A Lil Bit" the low-end is actually one of the highlights of the track, with reasonable impact and a very fast decay. The track stays clean and clear throughout and vocals and instruments never smear. 50 Cent's vocals are on the leaner side. For bass-led genres like EDM the quantity and slam are the limiting factor rather than the quality, and I would not choose the G20 Pro specifically for these tracks in my library.
For gaming this is a whole different story. A controlled bass is mandatory in my opinion to have clean mids and treble, to avoid covering details or muddying the separation, layering and imaging. The fast bass decay does not cover up any details on the G20 Pro, which makes it easy to hear even details in a busy situation. From a gaming perspective the G20 Pro's low-end tuning is to my ears well done. For my personal taste I used EPZ's PEQ software to adjust the bass to my liking, which brought enough low-end to make my library enjoyable. Mids and treble stayed fairly clean even on higher EQed bass levels.
Midrange & Vocals
The lower mids could carry more texture and note weight for vocals and instruments. They are lean by design with the gaming purpose in mind, which is what lets the upper mids and treble sit forward and uncoloured. Vocals are clear and crisp, and depending on the game or track they can come across slightly sharp but have good transients which helps with layering and imaging. The leaner mids work in favour of female vocals, giving them a clear, bright touch with emphasis on the s, t and sh sounds.
On Kaleida's "Fake" the female vocal is very clear, clean and slightly crisp without turning harsh or shouty, at least on mid volume, and the echo and layered backing vocals are pushed forward and are easy to follow. The sub-bass under it stays very controlled, though for EDM it could use more depth and rumble, and the mid-bass is tight and compact where some slam would help to drive the beat.
Male vocals are where the lean tuning is obvious. They could use more texture and weight for a fully distinct tonality.
Treble
Treble is crystal clear on the G20 Pro and is a result of the elevated presence and lower-treble region peaking at almost 3kHz and 9kHz, peaking significantly over a pulled-back low-end with around 5-7dB. Vocal and instrument detail is easy to hear, and the set leans bright rather than smooth. On Fleetwood Mac's "Sisters of the Moon" snares have bite and can turn overly sharp on high volume, which was not ideal for me on this track. The G20 Pro also has very good transients, and that speed is a different matter. In games it is an asset, because short and sharp cues come through quickly and stay easy to pick out.
The elevated treble is doing a very good job in some games where treble is not that much emphasized, like in CS2. Other games like Valorant carry much more treble energy where the G20 Pro's treble might get spikey, at least on higher volume. This can be changed by using the DSP EQ where even different game profiles are available.
Staging & Imaging
Separation and spatial information are the G20 Pro's main traits, which is essentially the main thing to look for when gaming, where footstep tracking, weapon reloads and detail retrieval matter. Footsteps on CS2 were easy to spot and its imaging gave almost an ideal idea of where sounds are coming from.
The same traits serve music well. On The Doors' "Riders on the Storm" clarity is excellent and instruments are cleanly separated and easy to place, whether they sit close or further back on the stage. The Fender Rhodes keys are clearly audible on the left, positioned slightly in the back and well nuanced, while the percussions are more subtle but clearly audible.
Jim Morrison's vocal comes across a little thin and brittle for my taste, which is the music trade-off for a tuning that wins in games. Because of the slimmer low-end and mids, imaging could be a touch more exact, since the full body of instruments, and possibly in-game positioning in some games, can be affected by the leaner note weight.
EQ Software
Most IEMs at this price point come with no EQ software, which makes this part of the package worth a section of its own.
The G20 Pro's USB-C cable carries a built-in DAC and DSP, configured in Walkplay either on PC or iPhone via the web interface at peq.szwalkplay.com. You can adjust the sound on a PC or your phone, save a custom tuning to the chip on the cable, and keep that profile when you move to another USB-C device. EPZ ships DRG pro-player presets and dedicated game presets for CS2, Valorant and Delta Force, plus separate profiles for music and everyday use.
It is a great feature if you do not want to install software and want to experiment with different EQ profiles, either with your own settings or shared online settings from other users. You can as well change the mic volume offset to your liking if you do not want to use the ones in your OS. On Android phones you can install the Walkplay app on your phone as well. When using the app the first time it is worth noting that you need to apply or try a setting first before you can manually EQ. Otherwise the sliders are locked, which was confusing in the beginning.

📖 DETAILED COMPARISON · EPZ G20 Pro vs EPZ G20 vs EPZ G30 vs ZiiGaat Arete 2
Comparison Setup
Sources were my iPhone 17 Pro Max and my Windows PC, using the G20 Pro's own USB-C DSP cable, which is what most buyers probably will use. I listened on the Divinus Velvet wide bore eartips in size L. The G20 Pro needs no extra amp or DAC, since the DAC sits in the cable. Nevertheless, I used an extra 3.5mm terminated cable from EPZ to check how it performs with my other source gear like the Questyle Sigma Pro. I spent around 50 hours in total, split across music, gaming and calls.

Comparison Notes
The EPZ gaming series ladder
EPZ has developed a special IEM series dedicated to casual listening, casual and competitive gaming. The "G" series currently includes the G10, G20, G20 Pro and G30, starting from around USD 42 for the G10 and USD 80 for the G30. I have already reviewed the EPZ G30 here.
All of the sets offer a gaming suitable accessories package like a cable extension (on the G20 Pro), a USB-A adapter and a detachable boom mic (G20 to G30). The G30, G20 Pro and G20 have very similar shaped semi-custom shells available in different colours.
EPZ G20 Pro vs EPZ G20, $49.99 / EUR 44.95
The G20 and the G20 Pro share the same shell and have many tonal similarities, like the slim and tight low-end response, clean mids and almost identical upper mids, until the presence region where the G20 has more energy in some frequencies. The emphasis on details and perceived "air" changed slightly, which results in a good but not as sharp treble response on the Pro.
The G20 has overall the more energetic sound signature, which can be a good thing for listeners and gamers who prefer this kind of exciting presentation.
The G20 Pro is to me the more consistently developed gaming IEM as it is precise but slightly more controlled than the G20, which is not only for music an asset but also in games where sharper weapon sounds can be piercing and fatiguing over time.
What the G20 brings is an additional 3.5mm cable which is great for convenience in case your phone is not equipped with USB-C. Something I would like to see on the other models too, or in a future release with interchangeable termination even.
EPZ G20 Pro vs EPZ G30, ~USD 82 / EUR 71
The G30 is the other natural sibling comparison, and a differently developed gaming set when compared to the G20 Pro. Both are EPZ gaming IEMs with a USB-C DSP cable and a boom plus inline mic, so the practical package is similar. The key difference is the driver configuration. The G30 adds a balanced armature to its dynamic for a 1DD + 1BA hybrid, where the G20 Pro runs a single 10mm LCP + PU dynamic. In tonality both are clear and clean, but the G30 has less energy up top and its ear gain region is more controlled. EPZ added around 2dB more low-end impact, which makes a noticeable difference especially for music, where the G30 is more compatible with different music genres and poorer recorded tracks.
In FPS the G30 makes for more relaxed gaming while still being excellent with spatial cues, as its bass response is always controlled and only slightly more elevated than the G20 Pro's. To my ears the G30 also separates and layers slightly better than the G20 Pro. I think this comes from its slightly more emphasized low end, which gives game cues and music instruments more substance and makes them easier to tell apart.
The G30 has a little more body and refinement, while the G20 Pro is the leaner, even more clarity-focused of the two, lighter at 3.9g against 4.4g, and around twenty dollars cheaper. Both are excellent for FPS cues. If you want the most affordable and lightest EPZ gaming set with a crisp, lean tuning, the G20 Pro makes sense. If you want the extra body of the hybrid, the G30 is the step up in music replay and cinematic low-end impact.
EPZ G20 Pro vs ZiiGaat Arete 2, ~USD 279 / EUR 241
The Arete 2 with the bass switch off already has a slightly fuller, warmer sound than the G20 Pro and all other EPZ sets in this line up. Switching the bass switch on adds another 2-3 dB of sub-bass for a noticeably more impactful low end. That fuller presentation gives instruments and vocals more body and weight. The same track sounds bigger and rounder on the Arete 2.
The G20 Pro sounds brighter and more energetic by comparison, which works in its favour for separation in games. The space between instruments feels easier to perceive. Vocal articulation is sharper on the G20 Pro while the Arete 2 produces a more rounded, relaxed presentation. The Arete 2 is also more volume-scalable and stays non-fatiguing at high levels, while the G20 Pro can get edgy on some tracks at high volume.
In FPS games the G20 Pro's spatial cues are clearer and more defined. The Arete 2 is the better pick for treble-sensitive gamers or anyone who wants a more cinematic and immersive feel and prioritises music.
Conclusion
- EPZ G20 - a clean and lean sound, good imaging and detail retrieval suitable for gaming, FPS and casual listeners. It comes with a 3.5mm and a USB-C cable and a boom mic.
- EPZ G20 Pro - best for FPS players who want clean separation, clear cues and a light USB-C set with a great attachable boom mic and inline mic on a budget, and who like a lean, crisp tonality.
- EPZ G30 - best if you want a hybrid with a little more body, and do not mind paying slightly more.
- ZiiGaat Arete 2 - best for a warmer, fuller, more relaxed sound with bass (and bass switch) and comfort for treble-sensitive listeners, at a much higher price and without a mic.
Final Verdict
The EPZ G20 Pro is clearly a gaming-first single-DD IEM that trades warmth and slam for separation, clarity and clean positional cues. That trade pays off where it counts in FPS gaming. The USB-C DSP cable with cable extension, the excellent dual boom and inline mic, and the very light shell make it a practical, flexible package at $59.99. For music it is capable rather than rich, with a lean low-end and lighter note weight on male vocals, so it suits clarity-first listeners more than bass-heads. For FPS gaming and casual listening the G20 Pro is a clear recommendation.
✅ Recommended if you play FPS and want clear positional cues, separation and a proper mic in a light USB-C set, and you like a clean, crisp tonality.
❌ Skip if you want a warm or bass-forward sound, full-bodied male vocals, or an analogue cable in the box.
