HD660S Headphones

Best sounding headphones I’ve ever used. Get a high quality DAC amplifier to go with them if you plug into your phone.

Nice!

They sound great!...even hooked up to the computer! I was waiting to do this review because I was waiting for a Topping DX7 Pro DAC/headphone amp to arrive. Just was delivered last night. Hooked it up to my computer via USB and all I've got to say is...I like this! The headphones sound so clean and they are so comfortable...it's a beautiful thing! I'm so happy that I purchased this pair of headphones. Thank you very much to the people at audio46 for making this happen for me...and very quickly too, I might add! I wouldn't hesitate to purchase future products from your business.

Sennheiser HD 660S Headphones

Excellent choice of headphone for my home studio. Sennheiser's latest addition to the legendary 600 series line is definitely in keeping with their high quality products. Very happy with my purchase and the $100 price drop mad these an easy decision.
