## Description

From the manufacturer

Review: Premium item and Performance - I had a less expensive set up however I decided to upgrade having seen how the Wazza Air headphones performed. Out of the box after after a quick charge, pairing was a dream and it literally is plug and play - one into the guitar an the other into the amp. Latency isn't an issue and the sound quality is equally to having a lead plugged in but with none of the restrictions. The only thing I would have liked was for the transmitter to have been hinged to lay flat along the body of the guitar so I could leave it in when putting my guitar into its rack however that's a small quibble and the performance upgrade is noticeable. If you are prepared to pay the premium you will get a premium performance.
Review: 6 month update - solid, can't go wrong with boss. - I still haven't made my mind up on these. I have three guitars, one with active emgs, second with active fishman fluence and third with passive Seymour Duncan. Even though on the box it says it's designed for passive pickups, it seem to work fine on my guitars with active pickups. They are easy to set up. Edit: 6 months have passed, I've played 4 shows at the start of the year, and these haven't let me down. The lights are very helpful because I like to know in advance how much charge there is left, so even when playing shows if you suddenly find yourself in the red region, you will still have enough charge to finish the show. Although I always make sure they're charged a night before. My only criticism would be the bulkiness of the product. On two of my guitars it's not too much of an issue because of the jack position and guitars' body shape conceils it, but on my PRS (jack is in the most common placement), the transmitter sticks out too much. This is very noticeable. I wish that the transmitter's body was on a pivot so the bulk of it could have been adjusted and hidden.

## Questions & Answers

**Q: Will this work with a keyboard/synthesizer?**
A: Hello and thank you for your question about our products.
Use with a synthesizer is possible with our WL-20L product.
Note, however, that with tones that have strong dynamics, such as square wave, piano, and xylophone tones, the sound is distorted depending on the keyboard range, and so raising the volume level is not possible.
Use the instrument with the volume adjusted to a level where no sound distortion occurs.
Connect the transmitter to the synthesizer's OUTPUT jack.
To determine whether connecting the transmitter and receiver to the equipment you're using is possible, download and check the WL-T (Transmitter) Outline and WL-20/WL-20L (Receiver) Outline available via our official website.
If you want to use stereo sound, check whether simultaneous connection of two sets is possible.
Regards,

**Q: Do these work well with active pickups?**
A: Yes these work great a bit expensive but you only get what you pay for, ive used these on active and none active pickups and no problems A1  *****

**Q: Can I plug the receiver into headphone?**
A: No it would be like plugging headphones straight in to a guitar, there would be no sound as the signal needs to be amplified

**Q: Can you have 2 guitars in band on different channels using 2 systems**
A: Hi,

That is fine as long as you are linked on different channels.

Regards
