Nickel little finger batteries are already a stone age for such devices. For headphones for 1000r, this can still be forgivable, but not for these. When you want to decrease / increase the volume, you constantly get confused in the controls and knock down the setting. Otherwise, they are normal TV headphones for the elderly. You can connect several pairs of headphones to one base, but for this you will have to buy several complete sets (headphones + base). The manufacturer's website says that the headphones can be bought separately, but they are not on sale. But on the other hand, due to very slow charging, the bases not connected to the signal source have to be used as charging stations.
