There are very few reviews for this model, as well as for the brand as a whole, so I decided to write in more detail =) Before that, I used Koss Porta pro wireless, but because of the flimsy wiring, they fell into disrepair. Immediately the question arose of buying a new headset in modern realities. I wanted overheads, and from decent ones (according to reviews), they are mostly either full-sized or expensive. I stumbled upon this model, took a risk, and I think that I did not lose. Edifier WH500 is in no way inferior, and in a number of parameters, they are superior to Koss Porta pro. Charging was initially 85%, and during the first trial operation for 1 hour 20 minutes, it decreased . by 1%! Thus, the declared operating time can be twice as long. After more than an hour of wearing, the ears did not get tired at all. Periodically left the phone in another room - everything is clear. In general, while only positive emotions. And if you take into account the price of 3.5 thousand, then the Edifier WH500 is generally fire! Highly recommend to buy!
