The Communicator Earphones have a thick cord that resists tangles and come with 3 earbud tips – in latex or “deep-fit soft foam” – so you can find your best fit. They minimize ambient noise, and their 10mm drivers reproduce 20-20,000 Hz for full, rich sound. There’s a built-in microphone so you can use it with phones. If you’re using an iPhone or Blackberry, you can answer the phone and stop the music with a single button push. The earphones are compatible with devices using a 3.5mm jack, such as iPods, iPhones, most mp3 players and laptops. The Communicator Earphones are available in grey(shown), blue, or all black from the A + R Store for $65.00.
