To anyone who own Heavy, are they worth it?

If you want something wired, get yourself some Sennheiser HD600, HD650, or HD660S2's. Can't go wrong with ol mate Senny. Very balanced frequency curve on all 3 of these models, but the 660S2's have a little more low end bass. If you want Bluetooth headphones, I'm pretty happy with my Sony XM5's.

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

My pet peeve about Youtube Headphone Revievers

I stopped listening to 90% of those reviewers when the HD 660S2 came out and they all said it was mid and inferior to the 650 and 600. It's one of my favorite headphones to date, has notably better transients, separation and imaging than either of those two, and it's the first one I'd reach for befo

Just had one of the best listening experiences of my life

HD 490 Pro and HD 660S2 are solid options as well if you don't want to instantly break the bank. Also the new HEDDphone D1 is one the best option under $1000 that has new diaphragm material tech that should offer close to planar-like speed and super wide EQ headroom (as much as I love Sennheisers I'

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.

Favorite Flathead for Movies/TV Shows?

Probably either the Calf or Airpods. Normally I use the Calf at my PC, but if I'm going to watch an actual TV series or a film, I'll do that on my TV and just use the TV speakers. But sometimes I'll use Airpods or a TWS IEM to block out background noise, not so much because the tuning is the best fo

Should I sell my HD 600 and HD 550 for HD 660 S2?

Maybe try something like a Fiio FT1 Pro, or the Hifiman XS or Ananda? I use the FT1P at my office for music and YouTube, and I love them - they have a similar profile to Sennheiser with some warmth and vocal presence, with a crisper delivery and better low end bass that booms a bit more when called

HD 600 or HD 660S2?

You'll probably really enjoy the 660S2's if the extra hundred isn't going to break the bank. I recently wrote a review between the 650's and 660S2's, not quite the same but if you're interested in a bit of a longer opinion about 660S2's.
