Sennheiser - HD 660S

Have to disagree - have the 660 S2, & it’s more like 600, 650, 6XX on Hi Res sources. They have the mods warmth of the other 6 series, with extended bass & better defined treble & air. It’s a perfect all rounder & not muddy like the others. Like the other 6 series though, it doesn’t have the soundstage of the 8 series, but very, very pleasant for long listening sessions. Not for critical listening so much, but the detail is all there 660 S1 was definitely a miss, S2 is a hit & my daily driver.

hd660s. I love both its strength as well as its weaknesses, making it my favourite pair of gears

shp9500, makes me value good mids over boosted bass. Now I'm happy with both my hd660s and hd620s. I also got a few pair of iems which are great, but never actually use anymore. Still wondering if I should sell them lol

full sized. I pick my hd660s and even my hd620s over my ier m9 anytime

Awesome! This just might be my Dreams setup! I have the momentum 4 right now but i would love to upgrade to the HDB630 didt you have a momentum 4 before this? And at home i am rocking the sennheiser hd660s but i was looking into the D1!

try to find refurbished sennheiser hd660s, i got mine refurb for $300 from the sennheiser outlet, and they are amazing, great for mixing, great for games

I’ve had the Audeze lcd-x and sold them for both the lcd2 and lcd2 closed. LCD X are fantastic but I can get what I like outa the lcd 2 for 99% of what I use my headphones for, they sound so similar for most things just a little less bass imo, and the other 1% the lcd2 closed does its job (stupid lots of bass lol) I’ve had the sennheiser 660s and gave them to my best friend, I always felt like I was going to break them, But they sound great. I have both the hifiman sundara and sundara closed, these were replaced with my Audezes. They sound good for the price you can get them today but I like my audezes more. I also have the Moondrop Venus, those sit on a stand and I don’t use them. They weigh a damn ton and are no better than a sundara in sound but they’re beautiful lookin lol.

The right earcup always fall off the hinge and the material on earpads starts deteriorating after 6 months of daily use. I used to like these headphones but not anymore because build quality is bad. I switched to Sennheiser 660s and a usb mic.

Yeah I'd also go Sennheiser. I don't know what material they use for the 6xx series but my 660 feels so light and flimsy yet survived quite a few potentially fatal accidents without a scratch. Close second would be Beyerdynamic. I would use my DT770s to hammer in a nail no questions asked.

I had a similar journey, starting with gaming headsets like the JBL Quantum 910X and Logitech Pro X2. Around mid-2024, I began exploring Hi-Fi and studio headphones, first with a Fiio K11 and a pair of HD660S, then upgrading to the HD660S2. I eventually settled on the closed-back DT1770 MK2 paired with a Fiio K19 as my daily drivers, and they’ve been excellent. I also own a pair of DT 900 Pro X open-backs and have been tempted to swap them for the DT1990 Pro MK2.

I mean, I also started with Beyers and there is nothing wrong with them. I remember hearing them for the first time thinking the same. It was a pair of DT770. Then I grabbed a pair of open backs, the HD660s and was shocked on how good open backs can sound. I side tracked for a few months with all other variants, DT880, HD600/650 etc and eventually I stepped up to LCD-X. It was like getting into the hobby once again. I had my mind blown on how good headphones can really sound. After the LCD-Xs tbh I tried various amounts of ZMFs, listened to Hifimans, Mezes in shops but ultimately I found my one and done, the Tungsten and never looked back ever since. I'm coming up to my 2yr anniversary of owning them and not buying anything else. Point is, if you like them and think they sound good and they do everything for you, don't look elsewhere. Diminishing returns hit hard after the LCD-X so take care

Gaming branded stuff is generally overpriced for what you get. You're paying for the convenience of an integrated mic and RGB lights. Id get a good set of normal headphones and an Antlion mic. They're small mics that attach to headphones with a speedball type mount. Its a great mic and it works with any headphones! I have the HD660 from Sennheiser and the Antlion Mod Mic Wireless and like it a lot.
