IMHO, what is missing in them is the ability to play and communicate in discord without a wire via bluetooth on a computer with normal voice quality. They do not know how to transmit voice without a wire in HD quality. In general - only via USB, keep in mind if you are looking for a wireless headset for communication - this is not about them. But these are trifles, they were bought for stationary use. Now about the main disadvantage, it is actually one and crosses out all the advantages: They won't last more than a year! Physically, the structure that holds the speakers will break sooner or later, your ear will simply fall off. Even repeating the revision with stiffeners - it will break! Exactly what happened to me. The first headphones lived for about a year, they broke, I found out somewhere in the comments that they were being replaced under warranty, and this is true. You send a parcel to America and you will get new ones back, BUT, they will still break, that's the paradox! So I already have a second pair, they came by replacement, with ribs. Knowing that they are flimsy, I used them less often, but they already cracked on my right ear (I don’t attach a photo, there are hundreds of identical photos from other buyers, everything is the same) In general, I’m not upset anymore, it’s a pity there are NO alternatives on the market sound with the same functionality. One thing pleases, I found a kulibin with ebay, who prints these fasteners on a 3d print. (and they are thicker in the photo 5 times than on the original) I think now after the replacement, this flimsy part will definitely not break physically. The truth will have to be soldered. Well, that's okay. All the same, they are worth their money for the sound. But I would NOT RECOMMEND for buying, unless with a replacement for a custom part. if your ear rustles - just wait, it will pass. most likely you hit them and crushed the membrane, which will actually straighten up in 2-3-4 months. This is not a warranty case, an examination will send you. Yes, annoying, but then it will pass. Do not wrinkle the membrane, do not slap the soft part of the ear pad with your palm and everything will be ok until the earpiece itself falls off =) Unsubscribe after replacing the part, after a while.
