The USA flag-blue Otto Engineering Bluetooth Revo NC2 combines Bluetooth technology and high-definition audio to take speaker-mic functionality to a new level. Built-in Bluetooth wirelessly pairs with smartphones, tablets, and selected Bluetooth-enabled two-way radios to provide convenient hands-free listening and easy push-to-talk without the safety hazard of a cable connection. The specially designed high-definition audio amplifier ensures every transmission is heard clearly and accurately for greater mission success.

The Bluetooth Revo NC2 also features a patented, high-performance noise-canceling microphone that ensures optimum voice clarity in high-noise situations. The large, textured push-to-talk and volume buttons are easy to use, even with gloves, and an optional earpiece can be added for private listening.

The Bluetooth Revo NC2 is ideal for law enforcement, military, disaster recovery, and commercial settings. It eliminates the need to dig a phone out of a pocket, unlock a screen or deal with the safety hazard of a cable connection. Equipped with high-definition voice audio technology, the Bluetooth Revo NC2 is capable of producing sharper, less robotic and easier to understand transmissions than standard audio.

Outstanding clarity, enhanced understanding, faster response time to urgent commands and less frustration and fatigue all add up to greater safety and better outcomes.

Q: 3. How does it handle stereo?

A: Volume is a little low. I believe that since I plug it into the earphone jack of a computer, it combines both channels from a stereo feed into one output on the earpiece, rather than randomly choosing only one channel over the other. Sound quality is barely acceptable. With that being said, I use it to listen to my guests as I conduct live or recorded video interviews over the internet and I prefer an earpiece that is not very visible. iPhone earbuds will give you better quality, but are more visible.
