Ultracompact in-ear monitoring

The ultracompact Swiff Audio WX520 Monitor Wireless System was specially developed as lightweight, mobile solution for in-ear monitoring. This simple, effective set consists of nothing more than a receiver, a transmitter – which doubles as the carry case for both the receiver – and a charging cable. Despite this simplicity, the system transmits over the SHF 5.8GHz band, for a strong, stable, and uninterrupted signal. And with latency under 5ms, the audio itself stays crystal clear even at the loudest settings. The transmitter is capable of either mono or stereo output, thanks to its dual XLR (stereo) and 6.3mm (mono) sockets. This base unit is also the set's carry case, with space to store and charge the receiver, which is a compact belt-clip design with a headphone out for the user's in-ears. It also has an integrated display for managing the signal itself. The Swiff WX520 is a compact and easy-to-handle in-ear system with the flexibility to be used in countless different ways.

Incredibly easy to use

The receiver on the Swiff WX520 is fitted with a generously sized rotary dial for setting the volume; it's large enough for the integrated display, which shows the signal status, volume level, battery charge, and whether it’s muted. To switch it on or off, the volume dial simply needs to be held down for two seconds. For charging, the receiver docks into the transmitter, which is integrated into the carry case. The transmitter itself has a smaller volume knob that controls the signal going through the 6.3mm jack socket. Above that are switches for toggling between line and mic level, and between stereo and mono. The connectors on the right-hand side give a flexible range of options, though only one can be used at a time. On the front, there's the button for powering the transmitter on and off.

Swiff Audio WX520 Monitor Wireless System, Detail

Looking for freedom

This compact wireless system is aimed at musicians and sound engineers looking for more freedom to move on stage – and with a range of up to 50m, there's plenty of freedom. It can be used for band rehearsals, conferences, or sending audio to a camera when recording video content: At a stroke, long cable runs are a thing of the past. The system can be expanded with up to four extra receivers, each picking up the same signal. That way, several people can share one setup – for a tidy signal flow. Thanks to USB charging, there's no need for batteries to keep it powered.

About Swiff Audio

Swiff Audio Technology Co. Ltd. is based in Hong Kong and specialises in developing and manufacturing high-quality, intuitive wireless systems, backed by its more than 15 years of experience. Its product range includes wireless audio transmission systems, wireless amplifiers, tuners, and power supplies for effects pedals with adjustable voltage. 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.

Safe and secure signal

For a solid signal, musicians 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 the band or sound techs run the system on, the Swiff Audio WX520 can transmit for up to eight hours on a full charge. And with a signal-to-noise ratio of over 90dB and a distortion level of under 0.05%, it delivers high-quality audio, which is of course the most important thing of all.

Unacceptable audio quality
GtrLux 26.01.2026
I've been looking for an IEM system with these features and format my whole life and I really wanted to like this one... but the audio quality is truly unacceptable. It completely destroys the high frequencies, I can hear digital artifacts everywhere compared to a cabled connection. I can't figure out how other people can say this product sounds good... just a couple of other reviews are mentioning the poor audio quality. I want to remind you all that this is a wireless system with DIGITAL audio transmission, not ANALOG. Therefore, the quality of the transmitted signal SHOULD BE PRISTINE just like the quality of a cabled connection. "Better audio quality" is the only reason digital wireless transmissions were invented... and so having a digital transmission that degrades the sound instead, is a complete non sense. Another thing I want to mention is that the Aux/Line switch of my unit apparently does absolutely nothing. I can switch it back and forth and nothing happens to my ears... I don't know if it's broken or what. I'm returning this thing to get a MiPro hoping it is better.

The best IEM for traveling!
The Latin Ensemble 13.11.2025
I always carried my LD IEM with a Gator case on the baggage when I flight, along with my Beta 58 wireless... but tired of the space those occupy, when I saw on he Thomann web site browsing for another IEM (I have actually 6 systems but none have the audio quality of the LD) this Swiff Audio I've decided to try it. What a nice surprise! and now I ask for a microphone, carrying that tiny and beautiful box... the band that worked with me last time they were so curious about that tiny IEM.
PROS: Tiny, compact, beautiful, crystal clear sound, robust, options on connections and the possibility to get stereo (I don't use it, no need) and very good battery duration (they don't lie, I performed for 4 hours, at the end it was half of charge).
CONS: Signal. It loses it easy, in my case I perform all time "inside" the stage, behind FOH, but if as part of the show I go to the public in a dance court, as the last gig, I lost the signal, When I went to the bathroom, I have them on, and just closing the door I lost signal as well, but my friend, on the last gig, I gave it to her and use my traditional LD, she was so happy and she never lost connection, I think it depends on the place.

Cheap and easy
JimmyJamJerusalem 14.04.2025
Nice tactile unit, clips on belt, idea for live performance. Struggles a little with range when used around the house - walls, power outlets, wifi etc all effect the range but overall I'm happy with it. Very easy to use!

I've wanted something like this ever since I started using iems to DJ with. I run this out of my mixer so I can bounce about a bit. 0 noticeable latency and no noticeable sound degradation in the signal. Skip the pioneer & aiaiai ecosystem and use whatever headphones you want !
