I purchased this product 15 days ago. I tested it by repeating and with my bass guitar. It works really well. The sound reproduction is very faithful and breathless. Super easy to use, you put a 9V battery in the receiver (8 hours), we choose a channel (8 choices) on the transmitter and put the same on the receiver, it waits 2 seconds and it roll! Before I had tried a low-end model AKG was a disaster! So I hesitated between PG14E PGX14 and because I wanted above all the good stuff even if I ruin me. A friend who has this model for 2 years told me that there was no need to pay double for this model is already of excellent quality! They are 2 to use it as a group (set to channels 1 and 2) + singer with a SENNHEISER and it works really well! Of 40 concerts they have never had to change frequency (due to possible interference).

My only regret is missing the plastic case to put the equipment.

I truly believe I made the right choice!

After more than two years, it's still on top! J bought two rechargeable batteries of high quality, I provide more than 2:30 in conjunction with a single battery.
