    • DancinDave.Rocks Says The Shure BLX14/SM31-H9 Rocks!
style: H9: 512-542 MHz
I'm a street performer in Santa Monica (more about me at dancindave.rocks) and I sing and dance top 40 using the Shure BLX 14/SM31-H9 wireless headset. My dancing is vigorous and athletic and I jump around a lot and execute martial arts moves as well. The Shure BLX is a fantastic microphone. I am completely independent and no I didn't submit this review for any form of compensation. I have never owned a Shure before so I was impressed with the quality. The Shure stays in place when I move around and the sound quality is astounding. It allows me to sing softly and still be heard clearly which is important because I often do 4 - 6 hours of shows per day and so I don't get as tired and my voice lasts longer with it. Usually, I can do my show and never even have to think about the mic which is great. I strongly recommend it for musicians as well as aerobics instructors. ... show more

    • Love it!
style: H10: 542-572 MHz
I was leary of buying this. I don't know much about this type of equipment, but it was easy to set up and use. It did need another cord to plug into my speaker system. One of the men helped me figure that out. Make sure you know how you'll plug the receiver into your speaker. So far I love it and so do my students. I have over 60 folks in my classes some days. They can now hear both my music and me with no problem. ... show more

Dont waste your money on the cheap products. Spend the money and get a quality product! I run a gym and use this DAILY, no issues and sounds incredible.

    • Love this thing! Works great and is very tough.
style: H10: 542-572 MHz
Pros: I have used this for a while now and really like it! I never cuts out, has decent sound for the included mic but most impressive of all, it is really tough. I used it in a live show and somehow it flew off and was wrapped around a chair leg, pulled tight and yanked. Still worked perfectly. Very glad I got this one. Con: The sound has a little too much bass but as long as you can change the EQ a little you are good. ... show more

    • The microphone would cut in and out like a faulty wire and it was very frustrating
style: H9: 512-542 MHz
This was an expensive piece of equipment that quit working quickly. The microphone would cut in and out like a faulty wire and it was very frustrating. I purchased another headset piece thinking that would solve the problem No. Changing the batteries, switching stations, nothing helped with the erratic connection and cutting in and out. Very disappointed with this and would not recommend this product. ... show more

    • Amazing Sound!
style: H9: 512-542 MHz
This device sounds as good, if not better, than any of my stationary Audio-Technica or other Shure mics. Battery life isn't anything game-changing, but I did 2 gigs (about 6 hours) on a single battery, so that's not bad, and they're simple AA batteries, so cheap to get/replace. I haven't tested how far the range is, since I'm typically pretty close to the receiver, but I've never experienced even the slightest latency or sound-fidelity loss in distancing myself from the receiver. The headset is comfortable and has no issues with my rather clammy head after several hours of performing. Great product! ... show more

    • Very disappointed
style: H9: 512-542 MHz
1st of all there's no English directions whatsoever. And there is no cord to hook up to the transmitter to hook up to your sound system. Very disappointing

    • Great wireless microphone!
style: H9: 512-542 MHz
Wow! This wireless microphone did exactly what I needed for my outdoor yoga class and more. Easy to set up, clear, crisp sound and at times, I forgot I had in on as it was very comfortable to wear. During an intensive part of my class, I could easily turn the micro away from my mouth to lessen my breathing sounds. It is worth the price ten times over. After much research, I am very happy with this purchase. ... show more
