Beyerdynamic

Bluetooth speakers are usually made for listening to music with, but you can also use them as hands-free speakerphones for calls when connected to your smartphone or computer. Interestingly, the wireless speaker I'm reviewing here works quite differently to mainstream options, in that it isn't focused on the music listening experience at all. The Beyerdynamic Phonum is a wireless speakerphone made specifically for voice communications – whether phone calls or Internet-based audio and video conferencing – and connects to a source device using either Bluetooth or a wired USB connection.
