Rated 5 out of 5

Simple and easy

We already had a set and in needs of a secondary set. We were on the fence between this or it’s big brother BLX88. We ended with buying this. The setup was simple and easy (a single push of a button and making sure the sender channel matches the receiver) and did not cause any issues with our existing set.

Shure Blx14/p31 beats them all!!!

Great price. Sounds like a ($) head set system for half the price. The transmitter although is tiny, don't let that fool you....it has a one button scanner for best reception that hits it right on the nose...ooohhh wait a minute...it has no external antenna. Don't let that fool you either, because it does deliver the 300 ft. power to your reciver with the know Shure quality of a wired Shure microphone just as it states on the description of the item. This is my third week of using this wireless head set system in our mid size Church. I'm the music minister of this Church with 39 years experience as a piano, bass guitar and acoustic guitar player. I am also a certified electronic thechnician with 40 years experience and with 23 years as a windows platform computer thechnician. I'm also very happy that I read all the previous reviews I could find to make a wise decision and choice on this purchase and truly hope you can find my review helpfull in your quest on looking for the best one at right price.
