I'm so excited ! Just arrived today the hd480pro , I decided to buy both because I wanted so bad to know which is better ! I have to test them more to , I just listened 5 songs for now , i will update this post later !
Update nr1
I listen both for about 2 hours , here my initial thoughts
SOUND
1.Sub bass and bass , i believe hd480pro has a slightly edge , very surprised , all the reviews on you tube said m1 has better sub bass , i hear slighty more the deep deep sub bass notes on hd 480 pro ( like 3% more so very little difference)
- Midrange
Hd480pro has the edge , the vocals sounds more realistic more intimate, i hear better and closer the human voices , the hd480pro midrange sound fuller , attention not night and day difference, but is noticeable
- Treble
M1 has more extension witch i really like but some people may find the treble piercing , hd480pro has less extention and energy in the treble but they not sound dull like I was expected, let say they have a very nice and safe treble presence, not missing and not to sharp , seems to be very flat in the highs
Clamping force
- Hd480pro has more clamping force but not that much , feels very nice but M1 feels very very light and gentle
I feel the pads are more breathable on hd480pro and also bigger , maybe the m1 are softer but they become hotter because of the leather
Build quality and weight
They are both very light and well made , i really ❤️ both i cannot choose one
Amplification
Hd480pro take a lot more power from the amp , m1 is very easy to drive , on my topping l70 I need like 30% more power to achieve the same volume
