Characteristically, Sennheiser has a reputation for warmth in their sound delivery, and the EW 135 doesn't disappoint. The set-up is fairly simple, and like many units in this class, the unit is a small half rack. The range is good, and the UHF tuning bands ensure a channel free of interference. Sounds like every other wireless system? Rather, it is the characteristic delivery of warmth that sets Sennheiser apart from competitors. If you are looking for that extra warmth in vocals or instruments and are tired of the serile clinical sound, this baby is the one for you!
