Wireless IEM System 5.8G in Ear Monitor Transmitter Receiver | 5.8G wireless in ear monitor system with transmitter, receiver, dual monitoring and Type-C audio connection

Works great, sound is perfect. I used them for my metal detector because they have no (or no noticable) delay like many Bluetooth devices have.

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.

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

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.

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

Works great
