Very good headphones, my first dip into better headphones and I really like them. I bought them refurbished and they arrived quickly and looked like brand new.

Extremely happy with the decision to buy ‘refurbished’ - they look absolutely brand new! Very impressed. For me their sound is near perfect: nicely controlled bass, detail and clarity. Highly recommended.

well-known brand and a great product

Great product for consumer and pro users. For very critical listeners its better to calibrate with REW or similar tools.
Further, the product is in a new state, it is absolutely worth money spent.

Refurbished are as good as new

I had one retail pair beforehand, and bought this refurbished set to use as PC headphones. My new motherboard (MSI Z690i Unify) has great support with headphone impedance sensing, so no need for external AMP/DAC with the 660s. Very happy with the sound quality, and the ease of wear.

Fantastic

Nice and tightly controlled bass. Mids are neutral and detailed (not forward or recessed). Highs are balanced but not piercing and sharp. Driver and pad burn-in was very quick (<10 hours) and sound improved and became more cohesive.

10/10 build quality and comfort. 9/10 overall…would have liked a bit more sub bass extension.
Overall happy with the purchase, my favorite of the 6 series.
