The phones will be fine, good sounding if I can wear them without pain! This design "One size fit all" is horrible. First, the loops for ears are to small for most peoples, then the connecting back may fit some kids but not an adult with hair. Even if you shave your head, you will find hard time to fit this headphones and wear them more then 20 minutes. All the other aspects, like distance, many different setups of transmitter for different devices are very good. The sound quality is acceptable for wireless device. If you got small ears and head with military haircut this maybe a product for you.
