Xvive U4T9 Wireless in-Ear Monitor System, U4 in-Ear Monitor System, T9 IEM Dual Knowles BA Drivers for Studio, Band Rehearsal,Live Performance(U4T9)

Our church's praise team started using ear in monitors. Yes, we started with the $20 stuff. That was bad. I was doing better with wired Samsung cell phone earbuds. Our bass player had quality in ear monitors and encouraged me to get better quality monitors. His $240 Westones were now over $400, a little pricey for me. After reading many reviews I decided to try the Xvive T9s.I started with the smallest foam buds. That was much better. I tried the medium foam buds and there was a dramatic increase in isolation from extraneous noise and I could hear all the parts from cymbals to my brother's excellent bass playing. The trick was finding the right foam pads. The T9s deliver great sound once the fit is right. I am very happy.

For the price these are amazing. The sound quality is very good and the build quality is also pretty good. I have not had them long enough to validate the battery life claim. The manual states that you should not connect it to USB power while turned on as this will reduce the battery life. This is unfortunate, but the price is still very good for the quality. If I could I would give it 4.5 stars for this reason.

This is easy to use, compact and reliable! I've used it for a 2 hour show without issues. A 3-hour show started to cut out towards the end. You do need to be pretty close to the receiver, though, and I doubt it would last any longer than 3 hours, so seems like you'd have to charge in between sets.

I have been very happy with the performance.Very easy to use. I shut if off between sets to conserve battery.A few times I had connections issues when everyone in the band was using wireless.

On time. Works great.

I bought these IEMs to replace damaged earbuds. I previously have used Samsung Galaxy Buds 2 Pro and Sony WF1000XM5. I have smaller ear canals, and the earbuds were always falling out of my ears and hitting the ground. I enjoyed the noise reduction features in the ear buds and worried that I would miss that going to the T9s. I am pleased to say that the T9s fit snugly and block out unwanted background noise as well as the noise cancelling ear buds did, or better. The ear hooks and cord keep the devices from falling to the ground if they do come loose for some reason. The cord is long enough that it isn't a problem attaching to my phone (using a usbc adaptor). The sound quality is really good, as expected. Another nice feature is the sound delivery tube is fairly large. This makes it easy to clean earwax from the entrance. Much easier than with earbuds and their small openings with a screen. I wish I had bought these sooner.

Outstanding solution for mid size gigs… no cuts out interference or delay… the best for the price

If you’re looking for a simple wireless in-ear system, this is for you. It operates on 2.4GHz WiFi, has six different frequencies you can choose from, and has a pretty good range—even through walls, two stories high.Comes with XLR transmitter and receiver, a ¼” to XLR adapter, a built-in metal clip on the receiver, and a USB to micro USB cable to charge both units from one USB port. You can use any regular headphones or in-ears to put into the receiver, as long as it is a TRS pin and not a TRRS pin. Easy to control volume, and a ON and OFF switch on both units.Two things I wish is, it would have been nice if the volume knob on the receiver had some type of notch on it, so you would know where the volume level was at when you have the pack clipped behind you. The second thing is, it would have been nice if it used USB-C cables instead of micro USB.Other than those two things, I would highly recommend this, if you want something compact and affordable.
