If you are using this for an in the ear or close to the ear audio source then it may be fine. But if you need high output, forget about it. I used this to try and send my Unication G5 Pager "Bluetooth equipped " output through my Dodge Charger Car audio system by plugging the 3.5 mm output into my Aux input on the car. It worked, but volume levels stink, stink, stink. Even with Pager, Bluetooth, and Car system turned up all the way, it was barely loud and sound quality was low fidelity. Also, there is a an announcement tone everytime a talkgroup transmits. Not a G4 G5 solution.
It feels cheap. It is cheap. But it works... cheaply.
