Frequently Asked Questions

What makes the SL-HDIEF better for shared radio environments?

The SL-HDIEF is specifically designed for multi-shift use. The earpiece detaches quickly from the PTT cable, allowing each user to have their own hygienic earpiece while the main cable stays with the radio.

What is the noise reduction rating of this earpiece?

It offers up to 48 dB of passive noise reduction when using the foam tips, making it highly effective in loud industrial and construction environments.

Is this earpiece compatible with my existing radio?

The SL-HDIEF works with any Atlantic Radio SnapLock PTT cable (1, 2, or 3-wire). The PTT cable must be purchased separately if you don’t already have one.

How often should I replace the foam tips?

For maximum hygiene and comfort, we recommend replacing the foam tips every 30–60 days depending on usage. Replacement tips are inexpensive and easy to swap.
