But this EarFun Tune Pro has completely dismantled my stance on everything. EarFun Tune Pro is a wireless Hi-Fi circumaural headphone with ANC. The EarFun Tune Pro moves at a frequency of 2.4 GHz and has a range of about 15 metres with a transmission of less than 7dBm, provided there are no obstacles in between. So, what is the magic of these EarFun Tune Pro? I could have dedicated this text weeks ago, talking about how the EarFun Tune Pro is a remarkable multi-purpose headset, both for listening to music, and for taking calls and participating in teleworking meetings with good microphone cadence.
