[+] The reception is of equal quality in every apartment, 20 m it does not move (but the quality is very questionable ...)
[+] The headphone is lightweight, comfortable and rather
[+] The installation is very simple
[-] The dial frequency is too easy to access, it disrupts the headphone easily unintentionally
[-] The reception is very poor, we always hear a slight noise, is common to all headsets?
[-] The sound quality itself is very average compared to a wired headset
The final product rather disappointing. The finishes are good, but the reception and sound quality is really more than average. I would not recommend this product.
