SENA Mesh Intercom + Bluetooth headset

Sena headset with a low-profile form factor that sits comfortably over the user's ears, while still allowing for acoustic awareness of surrounding sounds. 

The Expand Mesh has rounded arms located just above the speakers, which provide a secure hold on the head and ears. 
The device’s low-hanging neckband allows users to also wear a hat, climbing helmet, or glasses while using the Expand Mesh headset.
