Review on 🎧 AIRSN Earpiece Headset for Motorola SL300 SL7550 7580 7590 SL4000 SL3500e SL1K SL1M Walkie Talkie: Acoustic Tube Earpiece with Mic PTT by Stephen Schmidt

I liked the twin cables so I could place the earbud and mic where I needed it. Long enough to go under shirt and down to waist to attach belt attached radio. The only problem I had (and it might just have been the radio I had) was that the mic button would sometimes randomly stop working (always at the worst possible moment when you're trying to call a stage show), but found when I did the reached out and pushed a button on the radio, I was able to speak, and then the button on the remote worked again.
