Klein Electronics Bluetooth accessories for push-to-talk over cellular, available for iOS and Android. Starting with our BLU-RSM, it's compact, rugged, and has an extremely loud speaker. It also has volume buttons in the front and an earpiece port for a listen-only earpiece option.

Our noise-canceling Blu-Talk has two push-to-talk earpiece buttons: one on the canal and the other on the noise-canceling bottom microphone. It swivels for left or right ear use, and we also have volume buttons in the back with a large battery that lasts up to 12 hours.

Our BLU-PTT+ is very rugged and compatible with various push-to-talk applications. We included a Velcro strap to strap it around your steering wheel, or you can remove that and place it in your pocket, and the third option is to use the included double-sided piece of tape as a semi-permanent option and place it anywhere you need it.

Lastly, our Blu PTT Mini was built exclusively for the Zello Push-to-Talk application. It's lightweight, small, and affordable. It also includes a Velcro strap that you can wrap around your steering wheel or remove to place in your pocket. And lastly, you can also throw it around a lanyard to be able to communicate that way.
