My other guitarist and I both purchased this unit to try it out in out for our band.
All of the testing that I have done were with guitars.
Sound Quality. 5/5 Stars.
Here it is, sound quality, one of the most important aspects to many guitarists that are tone nuts. How does this compare to a high quality cable?
Simply put, this unit sounds amazing. You have the full feeling of dynamics and articulation with no lag time whatsoever. According to the manual there is a 6ms delay which is completely unnoticeable to me. There is a slight bass cut to the signal when compared to a cable. It's as if the lowest frequencies are slightly rolled off. This doesn't sound bad in any way and actually to my ears seems to get rid of some of the low mud and add clarity. One could argue that the tone actually seems to be improved. Other wireless units such as the line6 relay have a cable emulation mode which this one does not. When compared to a cable (based on sound quality alone) I would never hesitate to grab the Xvive U2 for any situation with maybe the exception for recording. There would NEVER be a point on stage where I would think to myself "having a wireless is nice for the freedom of movement , but I sure do wish it sounded and performed like a cable". I would take the Xvive U2 any time.
Ease of use 5/5 Stars
Turn both ends on and plug em in. That's it! Even if you are not tech savvy in any way there is not a single person on this planet that would have a hard time operating this unit. Think of this unit as less of a "guitar wireless system" and more of a "wireless cable." Just like a cable you have two 1/4 inch jacks, and that's it! Just plug in both ends just like you would a cable. There is no body pack transmitter to fumble with and no bulky receiver to plug in and mount on top of your amp or pedal board and plug in an ac adapter to power it. The Xvive U2 makes things much easier.
Reliability 3/5 Stars
Here is a category that I would have to take points away from. In other review's I see that many people have had units that have arrived dead, or quickly died. My other guitarist and I both ordered our own Xvive U2. I ordered both units using my amazon account. My other guitarists unit seemed fine for about a week, then suddenly his transmitter would not hold any charge at all. At first he thought he might have just left it on and forgot to recharge it, but he tried again and no luck. The light would light up to indicate that it is charging but it was just completely dead. I contacted Amazon customer service and they are sending a replacement. Also on my unit there seems to be a minor issue. Normally when the charge is complete the red light goes off to tell you its done. On my transmitter the red light never goes off to indicate a full charge so I don't know for sure when it is 100% done charging. There seems to be some quality control issues with this first batch. When I purchased my Xvive U2 it was only available in silver, but now it is also available in black. Hopefully they have fixed these quality control issues with the newer ones coming off the assembly line. Since my other guitarist and I both ordered a unit and one failed within a week that's only a 50% success rate. That being said, this unit is so awesome and impressive and convenient that I still would have to completely recommend this unit anyway. Amazon customer service was completely helpful and there is a replacement being mailed to me as of the writing of this review.
Advantages
*no cost to buy regular or rechargeable batteries
*extremely simple operation
*no need to set up a bulky wireless receiver on your amp/pedal board.
Disadvantages
*If the batteries are totally dead you can't just pop in fresh one, you would have to charge it up first.
*The battery is not replaceable, so once it is worn out it MAY only hold charge for a short time. This remains to be seen.
What I would like to see in the future.
*When I bought my Xvive U2 I wished it came in black instead of silver, Now I see that they also make it in black, so my first wish already came true.
*It comes with a usb y cable to charge both inits at the same time, but you will have to supply your own usb charging brick. This would have been a nice inclusion.
*Right now it comes in a very nicely designed cardboard case. Since you will mostly likely be transporting this wireless back and forth to your gig It would be nice if it came with some sort of a hard-shell plastic travel case, similar to what you would carry a pair of sunglasses in.
*In order to change channels on the unit you press the channel button and then it tells you if it is on channel 1,2,3,or 4 by blinking once, twice, thrice, or 4 times. It would be cool if future units used different colored led's for the different channel. Like Red, Blue Green or white for example.
*I would be cool if they made an XLR version to turn your mic intro a wireless mic too.
Conclusion.
BUY THIS UNIT!
This unit is amazing, Besides sounding and performing great, the price point makes it extremely affordable. I have owned several wireless units and this outperforms others that were in the $500 price range. Even with the hiccup of receiving a faulty unit, I still would have to give this a 5/5 star rating fore sure.
