Excellent headphones, after 15 years of headphones with wires, you fully understand how convenient it is to use headphones to work without wires. Has some pros: 1. They keep a charge perfectly; 2. Excellent microphone from all the headphones that I had; 3. Excellent signal reception range. Has some cons: Sometimes it happens that the connection is lost, but it seems that one of the neighbors turns on something and therefore the signal is lost. But it is enough to pull out the connector and turn it on again and everything works fine.
