Xvive U4 Set Wireless In-Ear System (2.4 GHz)

These have been excellent so far both during practice as well as live. We bought 3 separate ones in total to allow for separate mixes live, and the ability to use the 3 separate receivers with one transmitter has been useful for more intimate performances where there is only one channel.

Xvive U4 Set Wireless In-Ear System (2.4 GHz)

Bought 2 of these systems (for now - I will buy more) to help move our Church band over to a silent stage. After the first night of practice our lead singer said they were a fabulous improvement over the previous acoustic foldbacks and for the PA team it now make managing the stage sound so much more controllable.
The beauty of the XVive U4 is that it is SO easy to use- and just works! The transmitter and receiver have 6 separate frequencies available and each singer can dial into the foldback mix they want to listen to. And being silent feedback (to anyone else) we can now incorporate a click-track that only the band can hear. The receiver is very tactile and intuitive: One dial rotates for volume and one dial has a button to cycle through the 6 frequencies. This means you can operate it behind your back if you need; no need even to look down and check what settings you are on. I also love the fact that the receiver is so small and from a build quality point of view seems nicely solid.
I've had no issues with signal quality or dropout anywhere within sight of our stage; but then again on the stage itself no band member is more than maybe 10m away from the transmitter.
The ONLY thing you need to be aware of is to make sure you put them back on charge after use. The battery lasts 5 hours (they claim - not tested) which is more than enough for our use. But I think, when we've got the whole band moved over to these units, I'd like to have one or two spares just in case.
Overall a great unit and very much worth the price.

Xvive U4 Set Wireless In-Ear System (2.4 GHz)

To put it simply, this product is just solid. After a couple of uses, I plan to buy a few more. We have just started doing some live streaming and needed the hall to be a bit more quiet. I bought one of these for the main vocalist and he has been using it for a few weeks now. Not a single drop off and the sound quality on this is super even with basic headphones. This is definitely better than most IEM's at this price point (in fact I returned one immediately after buying this). I plan to expand our set and use more of these and I'm pretty sure I can fix my wifi channel to avoid any interference. Lovely product and top job by xvive.

Xvive U4 draadloze in-ear set – aanrader!

Erg tevreden over de Xvive U4. De set is super eenvoudig in gebruik: aansluiten, kanaal kiezen en je kunt direct spelen. De verbinding is stabiel, het geluid is helder en ik merk vrijwel geen vertraging.

De zender en ontvanger zijn compact en degelijk en de accu gaat ruim voldoende mee voor repetities en optredens. Vooral de vrijheid om zonder kabel aan de mengtafel te kunnen spelen is geweldig.

Kortom: een gebruiksvriendelijke en betrouwbare draadloze in-ear set met een uitstekende prijs-kwaliteitverhouding. Absoluut een aanrader!
