Got these headphones to replace a set of Cowin E7s that finally gave in after 8 years of daily use. The originals weren't available anymore, so I tried these. So far so good--seems to me the bass could be better; I'm thinking the overall sound quality could be better also. Of course I could always drop 200 bucks on a set that would solve these two minor (for me anyway) issues.They work fine, and I'm good with them.

Muy buenos los recomiendo para la raza que quiera conprra

The sound is ok when you have a solid connection. Not as good as my $30 wired headphones, but better than any earbuds I have tried in the same price range. The sound is somewhat muffled and bassy, clear enough, just seems like it is artificially equalized to favor a bassier sound. I would prefer more natural, balanced levels. But if you like less harsh highs and a richer low end you might like this. With the bass boost on it's way too bassy, IMO, a little like listening to a concert through a closed door.I have a lot of problems with the connection to my desktop computer. Often there is a bad garbling effect. Often there is latency of about .25 seconds. Sometimes reconnecting the dongle or headset helps, other times it makes it worse. I am not sure what's causing the issue, it may not be the headset but the dongle or some other device interfering. So far it seems to stay cleanly connected to my phone.The active noise cancelling is pretty dang slick. I have never owned headphones with real ANC and I was surprised at how well it works.The spring power squeezing the cups together is quite a bit too stiff for me. At rest, the cups are not separated as in the product photos, but pressed tight together as seen in the video reviews. This might be nice for someone who likes a really snug fit but for me it is uncomfortable. The cup pads are very comfy, there's just too much pressure.I have gone back to wired headphones for my PC but these might still get some use now and then.

Worked great for 3 or 4 months, then the battery started having problems charging. Such a disappointment for them not to even make it a year. I figured I would break them if anything happen to them, but instead they quit charging. Suprise.
