HD 490 PRO or HD 660S2
I actually own both. Short answer: the HD 490 Pro is way more versatile. Comfort is the first big difference. The 490 has larger and deeper cups, lighter clamp, and just more space in general. For long sessions, especially with bigger ears, it’s noticeably easier to live with. Sound-wise, the 660S2

Should I get HD490 PRO or HD660S2 after Audeze Maxwell
My vote is easily for the hd660s2. Own and game/listen to music for way too long everyday, I find myself reaching for the HD 660s2 no matter what. The 490 pros are a stellar can, and proof that Sennheiser can provide the perfect balance of consumer and mainstream in one cans tuning, with a great sou

This arrived today!
If it is not power enough you can make a combination with Zen can 3. A good and powerful combo for almost every pair of headphones. I use it with Sennheiser HD 660S2 and hifiman edition xs.

Do I have bad ears?
Hey there! Just curious, what are you plugging your HD660S2 into? I actually own both the HD660S2 and the wireless HDB630. I drive my 660S2 with a Topping DX5 II amp, and after some burn-in, it definitely doesn't lose to my wireless Sennheisers at all. The thing is, your Accentums have a built-in am

First DAP: FiiO M33 R2R vs HiBy R6 Pro II (2025 Cirrus version) for "British Sound"?
Different players not going to give you noticeably different sound. They just process digital format and output it to your IEMs / headphones. Now THOSE are where the difference is at. Get any player you like with good battery life and research sound profile of headphones that suits your exact needs.

What really good headphones are we using these days? Looking for rec’s from people who know good music.
What are you driving them with? Specific headphone amp, or just with your phone? Here are some recommendations of cans I’ve used in the past few years. I’ll just say that headphones, like speakers, are going to experience diminishing returns as you spend more money. And, like speakers, you should re

So apparently HiFiMAN might be the right brand for me? (According to AI at least)
Thanks man! I'll share with you something you might find interesting then, regrading what you wrote. A couple of days ago I posted something related to this project in the Sennheiser subreddit, someone there replied the following comment, which I then sent to Claude to respond to, I'll copy paste bo

Gaming headsets
Sennheiser HD 660s2. They are real good. You’ll need an amp to power them. Get a Fiio K5 Pro and call it a day. Will be a great setup.

Beginner from Korea seeking advice on Fantasy Ambient: How to fix muddy sound & EarPods vs. Monitor Headphones?
선생님이 잘 아시는 노래들도 똑같이 폰스피커에서 harsh하게 들리면 문제 없어여. 만약에 아니라면 장비 바꿔야 합니다. Deelay라는 공짜 플러그인 있는데 강추합니다. 3 애플 이어팟으로 작업하는건 비유하자면 맨손으로 요리할 고기 자르는 거에요. 좋은 헤드폰 꼭 사시는걸 추천드리고요... 돈 된다면 헤드폰 앰프도 사세요. 중고로 Sennheiser HD 660s2 추천드립니다. 나중에는 스피커도 사세여. 돈 없어서 서러운 마음은 잘 알지만...네...ㅠㅠ 돈 조금만 더 모으시고 좋은 헤드폰, 스피커, dac 사시길 바랍니당.

HD660s -> HD660s2 – should I "upgrade"?
The S2 is a clean improvement over the S in basically every way. Whether that's worth the extra money is up to you; if it were me, I'd look at a pair of 6XX instead as (to my ears at least) they're pretty equivalent. But honestly, I don't see any reason to buy any of the 600 series (other than maybe
