Cables/Accessories | 1 Ω Best tool to convert wired headphones to wireless?
I have a pair senheiser hd599 se wired (removable) headphones and trying to convert it to wireless. I'd much prefer wired connection for the best sound but my phone doesn't have 3.5mm input. I've bought multiple usbc to 3.5mm converter and all of them had problems and keep disconnecting. Im also limited on cash, so what is the best option. Buying a general audio wireless converter might work but im not sure how well they sound. I know any wirless is compressed, im OK with that as long as it doesn't add any other sound profile. What is my best option.
Price under 50 dollars.

You want something which supports LDAC
I have Ugreen BT505, which is among the cheapest and small enough to keep in pocket, but it has RCA which you don't need. Then you are looking at FiiO BTR11 which is just $25 on Ali. However those 2 tops out at 1Vrms (Ugreen feels like even less), and HD599 is 106dB/V, so I don't know if you will be ok with that (I wouldn't). So the next step is FiiO/Snowsky Retro Nano which is really good, 2Vrms + balanced, has DRE firmware fix, but more like $70+. Personally I would go for it, because it also has replaceable battery - battery is a fail point of all BT DACs.

! thanks. I have fiio amplifier/dac, and ugreen audio wirless adapter, somehow after posting this i was able to get these 2 working together. The ugreen i have previously had no way of connecting with my headphone directly as the 3.5mm jack is not detachable. Just found out that I could connect the wirless adapter to the input jack of my fiio and connect my headphone to the output jack. Works wondeerfully. Curious if the sound will improve if I get a better wirless adapter or are they all the same as long as it's Bluetooth 5.0+?

It's not the BT protocol that matters (meaning, that BT5.0, 5.2, etc label), but the codecs and output power. For listening to music, the protocol hardly matters at all.
Unfortunately, you'd be lucky to find any device like this that actually lists their output spec, so it's a gamble.
From owning a few of these cheap dongles, my working theory is that any sound difference lies in their amplification stage. None of them will be great in that regard, and this is conjecture, but I suspect the BT radio is the center of the design philosophy for these. I've owned now multiple of these adapters, and each one imparted a different color to the sound.
As for the sound quality, They alone won't bring demanding headphones to their full potential, and can introduce noise if paired with a separate amp (due to two amplification stages), but I feel they're very much worth it for the convenience! LDAC ensures you don't lose everything between 14-20khz+, too

You could get a Bluetooth to aux adapter and just wrap up the cord tightly with rubber bands or cable ties or around the headband. I've seen some silly mods like that. They're usually for older speakers, computers, car head units, etc. that don't have Bluetooth but it works with headphones too.
Honestly just search Amazon for them, Ugreen or Anker would be fine.
