How much is noise floor when no any sound is ...

How much is noise floor when no any sound is playing? How loud the noise floor compared to PSM300 and Sennheiser G4 IEM
Asked by: Zhixun
Neither Shure, Sennheiser, or Audio-Technica have provided specifications for the noise floor ratings of their IEM systems. While the Shure PSM 300 and Sennheiser ew IEM G4 systems have are very popular and have been around for many years, the Audio-Technica ATW-3255 3000 Series In-Ear Wireless Monitor System is a newer system that is proving to be a venerable contender with a much wider frequency band than the others. Noise does not appear to be an issue, but you should be aware that this system includes a built-in limiter for the output level to the headphones that users are reporting comes set by default to -30 dB, so you may want to change that setting or turn the limiter off, which is very easy to do.
