GTD Audio UHF 4 x100 Selectable Frequency Channels 2 Hand-held Wireless 2 Lavalier Lapel Headset Microphone 4 Mic System 33HL

The unit works very well as advertised with an occasional glitch on handmics that dropout depending on where the user is holding it.I purchased it for a class where the instructor uses a head mic and they pass around the other two microphones to the class to get any comments or remarks and it does as it is supposed to do except, like I said, the hand mics might drop out.Update: We. have used the unit for 3 classes and are having continuing issues with the 2 hand mics. GTD has replaced the 2 hand mics but we continue have drop out issues. I am trying to find frequencies that work better hoping that that will solve the issue.I will add more as we try to work through this.Also, know the dropout issues do not occur with the head mics and body packs as they have use an external antenna.Please know that GTD has been working with me to resolve these issues, for which I am very grateful.

Purchased these and used them at a robotics competition with very crowded RF frequencies. The mics were very reliable overall with only a couple signal drops. Audio quality was pretty good, with a very 'flat' sound (good for speech/announcing, acceptable for singing/instruments). Overall I would definitely recommend these to someone looking to purchase their first set of wireless mics and can't afford, or justify the cost of Shure or another pro brand.Pros: Inexpensive, Easily readable displays, strong connection, good audio quality.Cons: Plastic mics (would likely break if dropped), a couple signal drops, median battery life (~4-6 hours as opposed to the advertised 8).

Works great as long as you understand it has problems. There issues gives this system a so so rating.1. Battery indicator shows full charge when battery is almost completely dead.2. Eats batteries when not in use. Need to not have batteries installed, when not in use.3. Handheld design requires use of foam for good sound

This unit works better than expected and adds versatility to any DJ/KJ setup. It has good range with new batteries but you can hear the difference as the batteries ware. I recommend this unit to anyone.

It’s a simple set up and great sound quality.

Second mic never worked and all others went in and out. HAD TO HOLD WIRE TO GET ANY SOUND.Sadly, I had to return
