Wireless in Ear Monitor System 5.8G Wireless IEM System with Transmitter Receiver Earphone Monitor Transmission for Computer Phone Sound Card Studio Band

For the price, this is a great product. Good sound and good battery life.

Works fine for monitoring guitar but lag was very distracting for vocals.

If I could leave a zero star rating I would. Do not waste your time with purchasing these. I took the $25 gamble and they arrived and the sound was incredibly soft. Like I could barely hear anything In my in ears. Tried them with multiple input and output sources with the same terrible results. So now I have to drive 20 miles to an ups store just to return them. I’m not paying $7 to have Amazon pick them up out of principle. But just trust me, do not buy these.

The "summina Wireless in Ear Monitor System" is NOT, I repeat NOT 5.8Ghz. Don't be foolded. However, unless you're close to a microwave, a high powered wifi access point, or a miltary grade baby monitor, they work ok as a transmitter receiver pair. The dynamic range of the sound is thin like this seller's excuse for calling these 5.8G.

Received it sooner then promised, and a good deal for twenty five bucks. The sound quality is pretty good, with very little notable hiss. Range is similar to other brands of similar product. Have not checked their claim of 24 hour battery life, does not seem plausable but will update once tested. Like most chinese products poorley and inadequate documentation. it does have some unique features missing on competitors. The transmitter has a headphone port for monitoring the incomming line level signal from an RCA output or headphone output of a music player. This product would have been really unique if the TX had a second input port designed to be used with an stereo electret lavalier mic. The receiver has two heaphone jacks , so you can plugin two headphones , or use one port feeding into a sound system input while using a 2nd port forreceiver side headphone monitoring. Overall good enough for intended use as an stereo in ear monitor system for a small band fed from the mixer.

Works great

Easy to use but difficult to understand how to set up. Had a hard time getting it going on the first use.

I have different synthesizers that I like playing with. I wanted to try this and see if I could use it to simplify my setup with a wireless connection. For the most part, these are great. I did have issues with distortion at one point, but got most of those worked out. It's nice that these are rechargeable and use USB-C, so you can charge them easily. Having 2 headphone jacks on the receiver and one on the transmitter is very thoughtful and useful design. I can't imagine an ideal setup where you are using all of them, but I've had some pretty non-ideal setups, and extra jacks mean extra options, so that's great in my book. The first pairing was automatic, but it took a minute or so. I wasn't sure what to look for, until I saw the indicator lights turn solid blue, so the connection was easy, and you know when you are paired. After that, they seem to "remember" each other, and pair right away after turning them on. I attached the transmitter to my digital piano(with stereo sound) and tested it out. Early on I heard some hiss and pops, but the sound eventually cleared up and the silence was "true" silence, not a lot of background hiss or noise. When I started playing, the notes were clear, and yet the distortion was terrible. It sounded like the tone was good, but the notes were clipped. I tried different things and couldn't seem to fix it, but after some more troubleshooting, my problem turned out to be having the piano volume up too loud, and wasn't related to the wireless connection at all. I turned the piano volume down, and the monitor volume up, and everything sounded great from that point on. For all intents and purposes, it sounds as good as a direct connection, with very rare pops (but I had the units very close to each other so take that into consideration.) The little springy clips on back do not feel very durable. The one thing I really wish they had done differently is continuous volume control, instead of +/- buttons. There are a very limited number of volume settings, and a lot of the time, the volume I wanted was a little more than one setting, but less than the next setting. I was able to manage this using the volume control on my instrument, but that's not always possible. But even with that complaint, I don't know how you could get a better wireless monitoring system for this amount of money. It's a lot of bang for the buck.
