For some context, I bought this as a semi-temporary cordless headset while I'm waiting for a better pair of wireless headphones I'm getting through Kickstarter. After my last pair of decent-but-wired headphones went kaput I finally just had enough and bought these. The price is nothing to sneeze at, but you're not gonna get decent wireless headphones for much less than $100 (that might change soon, but as of the time I bought these the price was fair).
I expected some 'quirks' from a refurbished headset, and these have been decent. The battery seems a bit quick to drain - I end up plugging them in about every 1.5-2 days with consistent use. They also go to sleep what seems like a little too quickly? Supposedly a recent firmware update allows that to be adjusted, but so far there's no option in the old Logitec software (I had some problems with the newer version). The lights work, but I don't care too much about that. They're comfortable (the removable earpads are a nice touch, I might try to clean them soon) and the sound quality is decent. I've yet to have any problems that make me regret the purchase, but I also feel like there are better options by now for $80? All in all it's been a pretty positive experience.
