Xvive U2 Wireless Digital Transmitter/Receiver System for Guitar, Bass and Other Instruments, Rechargeable, 2.4 GHz Black

These things are a complete revelation. I use them on my semi-acoustic violin combined with a Roland Cube amp, and the rest of my band are sooooo jealous. I charge them up via USB every few practises, but other than that I am FREE from cables! It's so wonderful to be not tripping yourself or everyone up, and as we perform outside a lot and have to move between performance spots, it's a total revelation to not have trailing cables. Also I can move further from the band and do our own soundcheck while playing. I can't notice any difference sound-wise between using my lead and using these things, but we don't have a super hi-fi sound so that's not really a problem. Anyway, totally brilliant, well made, work well, and they came in a beautiful box which is a reassuring sign from the manufacturer. For the price they are a complete no-brainer, knowing what my band spend on their instruments. This combined with a £120 5-string semi-acoustic chinese eBay violin.. amazing. Don't hesitate.. just do it!

Bought these initially for use at home as I often move to and from the computer while practising guitar. Very easy to set up and I can't tell any difference in sound between these and using a cable. I have also used these recently at a few gigs and it is so much better not having a cable to trip over when squeezed up on a tight stage! The other great thing is that you can stand out front when doing a sound check which is very useful. They are made of plastic but feel fairly sturdy although the only thing I'd be a bit picky about is the on/off switches don't feel as good as the rest of the unit. Overall I'm very pleased and glad I've made the move to wireless. I don't think I'll look back now.

Some other reviewers have noted that this device doesn't work with their active pickups. The product packaging (but NOT the Amazon listing, tut tut) makes it clear that this MIGHT be a problem: "The U2 is suited for all electric string instruments with passive pickups. Performance with active pickups will vary depending on the type of pickup".My experience on that, for what it's worth, is positive. I've tried it with these active pickups:- Fishman Rare Earth soundhole humbucker (button battery)- Mimesis soundhole single coil (button)- B-Band A3T undersaddle (9v) factory-fitted in a Tanglewood acoustic guitar- Unknown brand 'ASE-N' (9v) factory-fitted in an Ozark tenor guitar- Fishman lsysT (?) (9v) factory-fitted in a Martin LX1E- Myers 'Feather' (button battery) and 'Clamp' (basically the same thing with two different mounts)It worked first time, every time, with all of them. The Myers ones were interesting because although Myers calls them 'pickups', they're actually little condenser microphones. This puts them outside the intended use, but they were just fine.I've also tried it with a slew of passive pickups including Seymour Duncan (humbucker) and K&K Twin (piezo discs, in a mandolin). You'd expect it to work well with them because it was designed for them. It did. It was specially nice on the Yamaha electric violin YEV-5 (passive), where cable drag can be a problem for the player.As far as I can tell, the sound quality is the same as with a cable. Of course, to test that, you've got to listen one way, then swap connectors and listen again. I don't know about you, but my ears have short memories. For what it's worth, it sounded the same to me. I'm reasonably fussy, your Coefficient of Fuss may vary.In the same way, volume level is the same as a cable. Same caveats apply.I tried it from two rooms away, say about twelve metres, through two concrete walls and a steel radiator. It worked. I tried it in the same room as my WiFi router. It worked.I've given it four rather than five stars because it seems a bit expensive for what it is - a cable replacement. I haven't gigged it yet. If it performs reliably at gigs where there are lots of magnetic fields and radio signals flying about, I'll put it up to six stars (© Nigel Tufnel) because then it will be worth its weight in gold. It weighs 41gms per unit, by the way. At today's UK gold price that would make the pair worth £113.57, so it's a pretty good gauge for once.

I've tried a couple of different wireless systems and - whilst technology has moved on since I first used them - I was still wary. A recommendation from a friend and these were the new chosen system. Super easy to setup, charged up from a USB cable which is so helpful as I even have one of those cables in my car so will never be left without charge.In terms of the performance, it didn't let me down over a 3 hour set. No delay and the only change to my sound was a slight tweak on the EQ on the amp for slightly less treble and a touch more bass. Minimal though and would highly recommend.

These units deliver great sound quality, a good battery life and just the joy of being free from the cable. No more tripping or tangling. Brilliant.Just one word of caution. If you have a guitar which gives you feedback problems now these may exacerbate them. I have a 2001 Gibson LG 3 which was always prone to feedback and just squeals when I try xvive with it. However, all my others, a strat and other electro-acoustics perform just as well as they did with high end cables fitted.

I loved this device when I first got it. It worked brilliantly. It only had light usage - and only at home. Recently it developed an intermittent connection fault. Initially I though it might be down to low battery. Having charged the device a couple of times now - it seems the intermittent signal is due to a fault. The sound stutters and cuts in and out - rendering the device useless. I accept it is a cheap wireless system - but even so it was over £100 and I expected it to last longer than a year. Very disappointed.

They are really good ,charge quickly ,good range, no noticeable loss of tone ,great if you like to move around on stage ,useful during a soundcheck at smaller venues .
