* Soft leatherette cushions ensure comfortable listening for extended periods of time * Operates on a single "AA" cell (not included) for 30 hours providing clean high fidelity dual channel sound - with or without the active noise cancellation * Adjustable headband provides greater comfort settings for different head sizes * ¼" stereo adapter allows use with amateur radio transceivers.

The new ambient noise reduction Heil 'Quiet Phone' is a result of many years of research and development at Heil Sound. This unique ambient noise cancelling technology uses two small mics placed deep inside the headphones that listen to the outside ambient noise as well as high quality program information.

The result is that everything below 400 Hz is eliminated allowing you to enjoy your programme source peacefully. Blower noise, ambient noise, jet engine noise, TV in the next room or - most importantly the second and third operator in the multi station operation is reduced by up to 70%. Truly a big step forward in amateur radio headphones and Heil Sound is proud to produce this high quality product.
