About this product

Product Description The Sennheiser RS 140 Wireless Balanced Headphones use a switchable dynamic compression system for excellent sound accuracy and balance control for optimum right/left volume adjustment. The adjustable high output level can compensate for minor hearing loss, and the auto-tuning mechanism with memory function finds crisp, clear music. The self-learning automatic level control provides optimum signal reception. Power comes from NiMH batteries that are recharged by simply putting the headphones on their transmitter base that can be mounted to a wall. A charge lasts for 23 hours. The RS 140 is backed by a two-year warranty.
