Nice one. I have the hd580 and newer version of hd600 plus a mint second hand 660s and I enjoy them all.

[@entrylevela1]

Thanks for sharing! That’s an amazing collection-you’ve got the best of the HD6-- series covered! Each one has its unique character, so I’m sure it’s a joy to switch between them depending on your mood.

For me the HD 600 remains the only legend of the 600 series.Thank you👍

[@entrylevela1]

The HD600 is definitely a timeless classic-many still consider it the true reference of the series. Glad you enjoyed the video, and thank you for watching! 👍

Great product

I think it's great neutral-warm versatile headphones, fits better for modern and fast paced music

[@entrylevela1]

The HD660S has that sweet neutral-warm sound that works so well with modern, fast-paced music. It's such a versatile pair of headphones. Thanks for sharing your take!

How to fix resonance in treble in 660S?

[@entrylevela1]

If you’re hearing treble resonance, try replacing the pads if they’re worn out or pairing the 660S with a tube amp like the Schiit Valhalla 2 or Feliks echo 2 to smooth things out. You can also use EQ to slightly lower the trouble frequencies. Hope this helps!

I have the 660s2 with fiiok7 is good Amp for them?

[@entrylevela1]

I tested both at my local audio store. From memory: the FiiO K7 is a good amp for the HD660S2. It has plenty of power to drive the S2 300ohm impedance and delivers a clean, balanced sound that pairs with the headphones’ warm and detailed signature. But, If you prefer more warmth or extra richness, pairing the S2 with a tube amp, like the Valhalla 2 or Feliks ECHO Mk2 (better choice IMO), could enhance the mids and add a more euphonic character.

[@assaf3468]

First of all, thank you very much for the recommendation. I feel like something is missing and as if they are capable of more. I feel like I just wasted money on the fiiok7 because I am new to this. Thanks to you, I will buy what you said. Oh, and one more thing, what should I set in Windows? Right now, I have 32-bit 96hz set. I don't understand it, and that sounds best to me, I think.

[@assaf3468]

I'm thinking about buying Valhalla 2 it looks good

[@entrylevela1]

@@assaf3468 You're very welcome! 😊 Don’t worry-getting into audio gear can feel a bit tricky at first, but the Fiio K7 is a solid choice. Windows Settings: Spotify: Set Windows to 16-bit 44.1kHz or 24/48 (try both) since Spotify streams at that quality. Also, enable high-quality streaming in the app preferences. Next level Qobuz or Tidal: Enable bit-perfect/exclusive mode in the app to bypass Windows processing. No need to set-up windows settings ;)

[@entrylevela1]

@@assaf3468 The Valhalla 2 pairs beautifully with high-impedance headphones like the Sennheiser HD6 series. However, I’d recommend buying it from a retailer with a good return policy, just in case it doesn’t meet your expectations. If you find the Valhalla 2 isn’t quite your style, you might want to check out Feliks Audio amps.

nice

Thank you!

Overpriced!

[@fraserhoggan9723]

Too much plastic

[@entrylevela1]

I get that! The HD660S does have a lot of plastic, but luckily it’s high-quality and keeps the headphones lightweight and comfortable.
