These work great and are cheap. I can finally hear my vocals and the rest of my band appreciates the lower stage volume. The wireless systems are awesome but super expensive so these serve a great purpose. The extra cables are a bit annoying but if you buy a headphone extension cable for your earbuds it allows you to mount on a mic stand or just put it on your amp. Also, if you have a limited number of monitor mixes the power center/4 way splitter makes it possible to send one mix out to 4 different boxes. Myself and the other singer in my band can agree fine on the vocal levels but not so much with our instrument levels. So instead of running our vocal mics through the box, we run our instruments (guitar cab mic/ keyboard) through and adjust the volume accordingly.

If this thing had TWO inputs I think it might be perfect. I am a singing drummer and it would be cool to be able to put a click track in along with my vocal mic, but otherwise this little thing is GREAT. Didn't notice a loss of fidelity...just using some Sony earbuds most of the time and the sound is fine (after it's been through the EQ). I'm recommending this to everyone I know who doesn't need a wireless system.

These little boxes are made rock solid. I have been involved in live sound and recording for almost 15 years and with the transition from wedges to IEM, this is your first natural step. For those that can't afford an Aviom or HearBack system, this little box will help in re-solve some (not all) of the issues that those same systems do. With a praise band of 8 members, we have moved from stage volume wars to these boxes. We have no wedges on the stage any more. Each musician gets a general mix from the board to a headphone splitter on stage and then to their personal monitor mix on the box. We then plug their instrument directly into the box and then into the sound system. No each musician will not have the control of every musician, but this at least lets them hear everything plus they can control how loud they are and the need for MON engineer is lessoned. If you lose quality in this sound then send it back and get another. These are a pass through box and should have no effect on the sound. These are a great solution to anyone need for a small budget fix for a better monitoring mix situation.

In a nutshell, these monitor boxes are nice for low-budget users, but for anyone who demands a clean and clear sound, stay away from these. As a combined MON/FOH operator, I appreciate the fact that people can add more or less of themselves without bothering me, but that's all they can do. While it relieves some duties from me, the quality loss both in the talent's ears as well as the pass-thru signal is completely not worth it.

Yes, that's correct, I said loss of quality for the pass-thru signal. With these boxes, that talent's instrument passes thru each box and then into the snake, thus making EVERY INSTRUMENT pass thru one of these boxes. I notice distortion on the keyborads, loss of fatness from the bass, a guitars that sound tinny and empty.

I've tried E1s, E3s, E4s, and Sony MDR's; same results. The limited on these is weak and cannot be trusted. I blew a pair of personal E4s i have used for months; one plug into the drummer's rolls, 30 seconds later the left ear blows and higher SPL distorts.

I have removed all of these from our stage set-up and WILL NEVER USE THEM AGAIN. I hope this review helps.

As a drummer who sings, for years I've had a really difficult time hearing myself through a monitor placed off to the side -- especially over the noise of an acoustic drum kit. I bought this personal monitor and combined it with the Shure E2 isolating in-ear monitors and was blown away. This little monitor not only lets you control how much of your own vocals you hear, but you can also control the monitor mix with a separate volume knob. I've only used it a couple of times, so I don't know if it's sturdy, but it works great.
