HR-1L
Medium-Weight, Single-Sided, Listen-Only Headphone with Pigtail Termination
The Telex HR-1L is a medium-weight, noise reduction headphone. It has a noise reduction rating of 21dB,
and is suitable for use in moderately noisy environments. The HR-1L features a unique, soft moleskin-
covered headband design that distributes ear cushion pressure evenly over the entire ear with no pressure
points, unlike conventional designs, which apply more pressure on the bottom of the ear than the top. An
added advantage of this design is that the headset folds into an extremely compact shape for ease of stor-
age and transportation.
