The Swiff Audio WX503 Wireless System is the perfect add-on for guitarists who want to lose the cables but keep the sound. This simple, effective set consists of nothing more than a transmitter, a receiver, and a sturdy case that doubles up as a charging station. Despite this simplicity, the system transmits over the SHF 5.8GHz band for a strong, stable, and uninterrupted signal – it's even encrypted. And with latency under 5ms, the audio itself stays crystal clear. Transmitter and receiver connect to source and PA through a standard 6.3mm jack socket, and each unit is powered by its integrated rechargeable battery: Fully charged, the system runs for up to six hours. With just a single multifunction button, plus an on/off switch, this compact, straightforward wireless setup gives guitarists the freedom to move around on stage without being tied down by cables.
The Swiff Audio WX503 Wireless System can handle frequencies from 20Hz to 20kHz, so even the deepest bass comes through with plenty of punch. Both outwardly identical components are so compact that they're flexible enough for use with almost any instrument. The transmitter plugs into a guitar and sends its signal to the receiver, which can be hooked up to any mixing desk. The multifunction button on each device - for switching channels, for example - also functions as an LED display showing the battery level, making it easy to see when a recharge is needed. The robust USB charging case that is included in the package can fully charge the transmitter/receiver pair up to three times before itself needing to recharge, and it also has a handy power display so guitarists will never get caught without juice.
This compact wireless system is aimed at guitarists looking for more freedom to move on stage - and a simple, intuitive solution to make it happen. With no extra controls, there's no complicated setup to worry about, and because it uses the very stable 5.8GHz frequency, between four and six units can be used on stage simultaneously. Similarly, one Swiff Audio WX503 transmitter can also be configured to send to up to four receivers, each outputting the same signal. That means a single guitarist could send their music to four different amps without even needing a mixing desk, and with the USB charging station, the show won't even need batteries.

All these products have proven their worth in countless settings – from stage and film sets to professional studios – and are aimed at musicians, performing artists, public speakers, and content creators.
For a solid signal, a guitarist will need a clear, direct line of sight between the transmitter and receiver, with as few large obstacles as possible in the way. Both units should also be at least 1.5 metres away from larger metal objects like walls or scaffolding: Because of the built-in lithium batteries, they shouldn't be placed near heat sources either. If the system isn't going to be used for a while, users should make sure not to keep the charging case plugged in for too long. Depending on which mode a musician or sound tech runs the system on, the Swiff Audio WX503 can transmit for six hours on a full charge. And with a signal-to-noise ratio of over 90dB and a distortion level of under 0.02%, it delivers high-quality audio, which is of course the most important thing of all.
