Review: Can’t beat the sound quality - Why did you pick this product vs others?: Love the sound quality
Review: Comfortable BT on ear with pretty good sound quality - I bought these to replace a broken set of Sennheiser EPOS SC 165 USB headphones. These are very similar construction, but with much thicker earpads (and BT obviously). Initially, the sound quality was not quite as good as the old ones. However, after just a few days, I've gotten used to it. It's not worse exactly, just different. More midrange, which I corrected with a third part eq app. Just a 2-3db cut around 500Hz was all it took to make them sound very nice. I use these for gaming, chat, work, and music. The volume control is a bit flimsy, and it makes a soft "beep" when you adjust it, which causes an odd interaction with whatever audio is playing. They are pricey, but far better than the $50 set I tried before these.
