Original Inrico Airtube Earphone AT-320 for POC Radio Inrico PTT T320 T400 Network Radio Headphone

The Inrico Airtube Earphone does the job and, as far as I know, is the only option compatible with Inrico radios—so if you need one, this is it. That said, there are a couple of issues worth noting.First, the talk button can be hit or miss. It only works if your radio is open to the talk page of the Zello channel, which can be frustrating if you forget to check before using it.Second, I wish the wire from the earpiece to the mic was longer. It’s just long enough to clip the earpiece to your collar and the mic to your lapel, but I’d prefer if the mic could reach my sleeve cuff instead for easier access.Overall, it’s decent for what it is, but there’s definitely room for improvement!
