The ultracompact Swiff Audio WS-70 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 charging cable. Despite this simplicity, the WS-70 boasts a latency under 5ms, so the audio itself stays crystal clear. The WS-70's two units connect to source and PA through a standard 6.3mm jack, which can be screwed off to reveal a 3.5mm jack beneath. Transmitter and receiver are powered by their integrated rechargeable batteries: Fully charged, the system runs for up to six hours. With just a single control for power on and off, this compact, straightforward wireless setup gives guitarists the freedom to move around on stage without being tied down by cables.
The Swiff Audio WS-70 Wireless System can handle frequencies from 20Hz to 20kHz, so even the deepest bass comes through with plenty of punch. It arrives with the transmitter and receiver clipped together; the top section is the transmitter, and the bottom is the receiver. The transmitter plugs into a guitar and sends its signal to the receiver, which then connects to a mixing desk. Both units feature a swivelling jack plug for flexible positioning, and each has its own on/off button. LEDs displays on both devices show the battery level, making it easy to see when a recharge is needed: The USB split cable the set ships with can charge both devices at once.
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. Its UHF frequency carrier means that up to ten devices can be used on stage at once, with no interference, although the systems will need testing first to elimante crossed signals. And with USB charging, even a ten-piece band won't need a single battery.

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 devices plugged in for too long. Depending on which mode a musician or sound tech runs the system on, the Swiff Audio WS-70 can transmit for up to ten 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.
