“I listened to a bunch of highly rated headphones at the last CanJam in NYC and none of them made me want to upgrade from the R70xa.”— this_is_me_drunk on Reddit
“I got the r70xa as well, but had to get a new amp to give it more juice to make it sing. But man, being so light i hardly reach for my other cans now and using these as daily drivers.”— Waste_Search2125 on Reddit
“it has this really arfticial, unnatural sound to it that's neither analytic nor is it a smooth, rich entertaining sound”— Overall-Cupcake7073 on Reddit
“What an incredible difference they make to everything I had before! You can listen to a track and hear subtle details that you did not even know they existed. Wow!”— @marco83 on YouTube
“HD650 with a bum driver, but I was able to solider the voice coil back on, so they work normally again. I had a pair 15 years ago and always regreted selling them.”— kindofbluetrains on Reddit
“I find the HiFiMan Sundara & the Fiio FT1 Pro both more useful for mixing - the Sennheisers have a much more condensed/flat sound with less bass extension than either of those”— @reallyoldcob on YouTube
Real owners lean toward the Sennheiser HD 650: 75% of 316 owners recommend it, vs 63% of 27 for the ATH-R70xa.
Owners point the ATH-R70xa at long listening sessions where light weight and all-day comfort matter most, and gamers and daily drivers wanting sharp imaging and a fun, dynamic sound.
Owners point the Sennheiser HD 650 at listeners wanting warm, non-fatiguing sound for long sessions, and vocal, acoustic, jazz, and classical lovers.
The most-cited downside of the ATH-R70xa is stock earpads run thin and can feel tight or press against the head, pushing many owners to swap in aftermarket R70X Refine pads for comfort. For the Sennheiser HD 650, it's rolled-off, light sub-bass that often needs EQ.
