No longer available at zZounds
Break free from the floor monitor wedge with this wireless in-ear monitor system from Audio-Technica. It comes with a transmitter, receiver and earphones.

The M2 Wireless In-Ear Monitor System is designed to make professional in-ear monitoring features accessible for performers who want to be free from the problems associated with floor wedges. The stereo monitor system offers Personal Mix Control, which gives each musician volume and mix control of two independent signals on stage, via easy-to-use controls on the M2R stereo body-pack receiver. The wireless UHF M2T Stereo Transmitter provides a choice of 100 selectable frequencies and is equipped with two combo input connectors(XLR/ 1/4 in.) into which users can connect line-level inputs. While up to 10 complete M2 systems may be used on stage simultaneously, any number of M2R stereo receivers may be used on the same frequency with a single M2T stereo transmitter. These rugged systems are built to stand up to the inevitable bumps of life on the road, delivering clear, natural sound for touring and installed-sound uses.

I would likely replace the M2 with another M2 as it meets my needs at a reasonable price. The only reason I would consider another model is if I ran into some contention with wireless frequencies but so far it has worked flawlessly everywhere I've used it.

Sound
The included ear buds are fine for general use but I've replaced them with Shure SCL5. OTherwise the sound quality including frequency range are very good. The optional limiter prevents the unit for exceeding safe listening levels. I've experienced no interference or dropouts at a distance of about 50 feet between the transmitter and body pack.

Features
The ability to feed the transmitter two channels off the sound board allows you to balance the receiver between one channel or the other. So for my mix I have vocals on one channel and the band on the other. Using the balance control on the body pack, I get both channels through both ear buds but can adjust the loudness of each to my preference. I have the vocals turned up slightly higher than the rest of the band. The ability to adjust the levels by myself rather than our sound guy gives me a custom mix. I always leave the limiter on to avoid exceeding safe listening levels. The body psck includes a jack to attach an ambient mic so that you can mix in audience sounds but I haven't found a need for this.

Ease of Use
Pretty simple really. Plug in any ear buds and adjust read more the overall volume and balance between the two channels. I replace the batteries before every show just to ensure that they don't run out during a performance. I do the same thing with my wireless guitar transmitter and mics.

Quality
So far the unit has held up well. I've dropped the body pack a couple of times but it has sustained no damage.

Manufacturer Support
I haven't had to contact the company for support.

The Wow Factor
Having made the transition from floor monitors to in-ear monitors, I can't imagine ever going back.
