Xvive U2 Guitar Wireless System - 2.4GHz 4 Channels Transmitter and Receiver for Electric Guitar, Bass, Violin

I just received this wireless transmitter set about a week ago, so I cannot meaningfully comment on battery life, but I can say that the transmitter and receiver set is easy to use, has a compact size, and seems to work great with both my active pickups (LR Baggs 5.0/under saddle transducer-piezo) and passive pickups (a proprietary system created by a luthier I go to, similar to a K&K Aloha/sound board transducer-inside contact). On the amp end, I am running it through an LR Baggs Synapse PA, and all the ukes I tested it with — Kamaka HF-2 concert (active), Kanile’a K-1 concert (active), KoAloha tenor and concert (both active), and Kamaka HF-1 soprano (passive) — sounded fine. I also tested the transmitter through a 5W Kala Mini Tweed with each of these same ukes, and all worked, though with varying volume (admittedly, I did this first, after just receiving the transmitter set, so maybe I had missed something that worked itself out by the next day when I tested with the Synapse PA).I am happy with my purchase.(Note: The set I purchased said “active pickup” in the type — the transmitter and receiver are kind of black and gray woven tweed in color. There is a similar all black set that I believe does not work as well with active pickup systems)

Range seems to be very good. Did not work well with a friend acoustic guitar with a aftermarket pickup. Has work very well with my electric basses. I have not fully tested battery life, but have gotten over 3 hours.

Clean sound, easy to use, no hassles with pairing!

I use this wireless system 4-8 hours a week. It works well and has a good effective range. It also recharges easily. I have two related difficulties: If there are other wireless users nearby, we all have to coordinate such that we aren't on the same wavelength. Also, when one handles the device one can easily accidentally reset the tiny/switches- not good in the middle of a set; in which case it's a good idea to keep a spare cord available.

Everything seem to work as promised. I haven’t used them at a gig, but I have used them at home and in practice as I just received them. It seems to be working as promised and I don’t know if any latency is detectable by human senses. I’m still getting used to being free of a cable. I’ve gone over three hours on them, but came home and changed up. They don’t have a charge level so I want to be sure they are ready for next time. I have tried to see how far I can go without losing the link, but I know 40 to 50 feet is no problem. I would recommend this product as it’s operation and and features work well and better than I expected. Great value for the price. The other guitar in the band got a pricier model, and it didn’t work any better for the money.

Product as described

I bought these in early Aug. and was very happy with them. Then, on Sept. 2nd, I hooked them up, and all I hear is a loud hiss in my amp and very little volume. I made sure they were fully charged and paired to the same channel - no help. Not sure what else to check. Nothing has changed with my set-up or location. Of course, I'm now past the return date.

I have used several different wireless systems. For the money, these can not be beat. Great sound. Quick connection. Easy to use and move. So good.
