SWIFF High-Grade Electronic Guitar Wireless System Rechargeable Guitar Transmitter Receiver Support Multi Channels and Long Battery Life for Electric Musical Instruments

I bought these for the 1st time in 2021, and they finally gave out last night (6-21-2025). I have gigged with these almost every weekend for 4 years and they've been excellent. I charge them in my vehicle on the way to the gig and they easily last the 4 hours of playing and could go much longer (my guess is around 6 hours of use). Super easy to use, just plug in and turn on and it's working. Excellent range, well over 100ft. I've been able to go wherever I want while playing with no latency or drop, outside or inside. The bang for the buck is unmatched in my opinion. I just ordered my 2nd set to replace the 1st now. If I could give 10 stars, I would.

Works quite well. I use on bass guitar. I bought the SWIFF WS-50 system running in the UHF frequency band because they have no noticeable interference with internet modems that run in the 2.4GHz band. I tries 2 different brands of 2.4GHz wireless units and they would have dropouts if used in a venue that was running wireless internet modems running in the 2.4GHz frequency band. After 2.5 years of limited use, the receiver battery does not hold charge as well as the transmitter. I always kept the units charged at least 50%-75% and would top them off for a gig. I am contacting SWIFF to see if they can replace my receiver unit. If not, I'll buy another set because I really like them. I have not noticed sound degradation or level decrease when switching between cable and these wireless units.

There is a noticeable drop in the high-end tone going from cable to wireless. The lower frequency response is also elevated. While the sound is good, it does not compare to the dynamic range I'm getting with my cable. I have the Adam Jones Epiphone, Custom Les Paul with a very hot 16.11 K Ohms Seymour Duncan distortion on the bridge and a 8K ohms custom-bucker on the neck, reverse mounted. So for this, I give it a MEH.

I’ve been using this wireless system on my violin for years and absolutely love it! It’s so easy to use and reliable in a variety of settings - I mostly use it at weddings and other events. It holds the charge well and makes amplifying so easy!

Charged right out of the box. Connected immediately, no noise, ready to rock. Nice units. Nice looking too. I have not tested the run time but if good I would purchase again.

In an effort to find a guitar wireless system that is reliable, has decent battery life, and doesn't introduce noise, I bought and returned 3 other brands, one at a time, before finding this one. Thankfully, my search finally ended with this model. I've had it for a couple months now and it has been great so far! The batteries easily last through 4-5 hour band practices as long as I remember to charge them beforehand, and the signal is clean and strong. I also love that there is a visual battery indicator on each piece so I know how much life they have left. For some reason, the receiver drains considerably faster than the transmitter, but that was the case with every brand I tried. Highly recommend!

I bought my set almost 2 years ago and started having an issue with battery life on one unit. I was going to buy another set from a different vendor but thought I would contact Swiff to see if there was anything I could do on my end to resolve the issue. Even though it was out of warranty, and I didn't ask for replacement, they sent me a new set. I will buy anything this company has for sale. Best customer support ever! Thanks!

I have only used it twice so far as I just received it so I cannot give it a 5 star rating. What I will say so far is that it is easy to set up and use and works great with my Blackie Strat that has active pickups. Sound seems great and there is zero drop out that i have experienced with other much more expensive devices like this. So far I am happy with this product and would buy it again if needed.
