No way Senn’s 560s are better ranked than 660S2 😣😣

Thats so funny because its the other way around for me. I sold my Arya Stealth to buy a 660S2.

hd550 is a fairly affordable and safe pick imo. If you don't mind eq the 560s is another good set. If you love vocals get something from the hd6-line. HD660S2 can be found anywhere near $400 these days

r/HeadphoneAdviceWhat might be the best headphones under 1000$

I got and returned the 109 Pro after few weeks. They are super comfortable, nice sounding and that is it. They are nice they didn't do much for me no complaints it just OK. I found my self going back more and more to my older Arya Stealth and 6xx. Obviously everyone is different but I think under $1000 there is much better at least objectively better headphones and you can listen to them first. Focal Clear, Arya Stealth, LCD-2C (used) I would even throw in 660S2. All these to me sounded better than 109 Pro.

I've tried the HD660S2, it did not impress me compared to the HD800s, I auditioned them back to back. My reaction to the HD660s2 was something along the lines of "Better bass better imaging version of the HD6XX (which are a third the price)." My reaction to the HD800s was... well I had no words I was blown away and moved to tears.

Now this is very good combo! The HD 660S2 are very often on my head and I honestly prefer them to the HD800. The K13 is very nice R2R-Dac/Amp which can make any good cans sing. This would be likely the one I'd buy if I needed a new setup.

r/headphonesTried the Fiio FT1… Am I Missing Something?

Had similar issues with my warm & dark sounding Senn 660S2s with extended sub bass where the sound was underwhelming, muffled like there was a blanket over the instruments when tested with PC, phone, portable minidisc and mp3 players.I even preferred my leaner and brighter sounding cheap HD 400S over them. What is night & day sound quality wise for me was a HiFi amp connected to my PC and even better, stereo amp/CD player.You know it as soon as you hear it, its always the clarity of the cymbals that leaps out and the wider space between instruments that make them all blend well together.

they're super comfortable in my opinion, people say that they're a bit tight out of the box but tthat never bothered me and i dont have a small head either. the bass is good, it's very detailed, but i found that after i EQ the lower bass frequencies up just the smallest bit, i enjoyed the headphone more. the sound is super clear and detailed, there are no weird peaks in the frequencies that start to tire you over time or anything like that. if i had to use some subjective words to describe the sound i'd say that it's really pleasant and relaxed, not boring though. and it IS very detailed
