Incredible
I'm not a proper audiophile, I was using the sony 1000xm3s before this which I was really happy with. But this Sennheiser is on a different level in every aspect except outright bass. I'm Starting to understand why audiophiles spend so much money on their audio.

Best all rounder headphones
I upgraded from bunch of headphones like the HD650 and the DT990 edition.The headphones build quality is good despite being lightweight, the earcups are bigger and puts less strain on someone like me who needs reading glasses.The sound is neutral type. Which means it's very good at mids if you have a neutral sounding DAC. Yes a DAC is needed since except my macbook M2 max not other device can drive it that good.The last thing is that these double as a very good gaming headset. Wish there was an option for a cable with a strap on mic like vmoda or my beyerdynamic for gaming. It's a missed opportunity I guess. Def justifies it's price.

Best sound quality
I use many wireless Bluetooth headphones from Bose and Sony. First time I’m trying to understand the Hi-Res headphones, definitely there is a noticeable difference when I listened first time with this Sennheiser HD660S2. But this needs an Amplifier/DAC, without amp/dac it’s not good, not portable like any other wireless headphones. I’m happy I bought this headphones, it’s amazing to listen some of the Hi-Res tracks.

Great Sound Quality, no ANC, tight fit
Extremely good sound quality, I have airpods pro 2, sony 1000xm5 headphones , a hyperx one .. and in pure sound clarity and quality terms , this beats all. But no ANC mode is probably the only con.
