4 Channel Wireless In-Ear Monitor Stereo S4

Awesome. All I can is wow. I've used many different types of ear monitor systems. From easy setup to simple syncing. I am currently using this on a short tour and have let other artists use them as well & all were impressed with mo loss of signal in buildings with a lot of concrete & metal. I was also impressed with the distance of connectivity even with all other wireless mics, guitar rigs, & wireless / wifi mixers. The loop outs are a smart idea. The only suggestion I would make is inputs being XLR as a sound tech. Special cords and adapters are fine but most things I use ( XAir, X32, M32, etc ) are all XLR out & think that most mixer auxiliaries are headed that way. Overall a great piece of equipment.

Worked right out of the box. Sounded good. Invest in the best earbuds you can afford. I bought this as an inexpensive IEM system for live gigs. I play every weekend as a guitar player, some vocals and run sound from the stage for a rock band. We recently decided to try to streamline the PA setup and stage volume by eliminating the stage monitors. I run an Allen & Heath QU-16 mixer. I wanted a stereo IEM setup for myself so I could hear a bit more of a detailed mix with the ability to pan some things out of the center. This system is inarguably extremely inexpensive, so I didn't expect miracles, but I finally got a chance to test it out yesterday and it worked immediately without having to pair the receiver. I sent it a stereo mix and everything just worked. I tested the range by walking away as far as I might on a typical stage and I had no issues with static or dropouts, even when not in direct eyesight of the transmitter. I would expect that a larger stage and having the antenna obscured from the receiver might be an issue at this price point, but for the average club musician, this shouldn't be an issue. My overall review is positive. I am a lifelong musician, recording engineer/producer and electronic technician (over 35 years). I understand how equipment like this works and I know the difference between "good" gear, "bad" gear and "cheap" gear. I am also not a gear snob (which might surprise those who know me!), so I have no problems using less-expensive gear, if it does what I require it to do. If I have any issues with this in the future as I start to gig with it, I will update this review if I can.

Funcionan al 100%. El empaque muy bien es un plus que incluye su estuche, pero lo más importante es que funciona excelente una calidad de sonido sin queja el ruido de fondo es muy bajo casi imperceptible el volumen tiene mucho rango lo probé en stereo y funciona sin problema, solo lo he probado en casa pero con eso puedo decir que el equipo tiene un desempeño ideal ya que no sufrí pérdida de señal ni ruidos o interferencias incluyendo paredes , techo y caminando por el patio con el transmisor en el 2do piso, estuve probando con las pilas incluidas por alrededor de 2 horas y el indicador de batería seguía mostrando al 100%. Super Recomendado.

A great and affordable IEM option. I am always looking for affordable sound options that don't sacrifice quality and as a result, ACEMIC is quickly becoming my most trusted brand. I was super excited to try out the Acemic S4 as I've used older models of their IEM systems and I wasn't disappointed. The build quality is great-everything looks good and is quite solid. The transmitter is metal and the receivers are metal as well. The stereo sound is great! Some of the best sound I've heard in more affordable IEM systems. We also really liked that the volume knob and power button are separate- the volume knob often acts as the power button in systems like this, but with them separate, you can set your volume and not worry about having to reset it between rehearsal/sound check and performance. We used them in our church where we actually have a lot of wireless signals flying through the air, so we also really appreciated the ability to change to one of the other 99 frequencies, as you have 100 options! All in all, I highly recommend the ACEMIC S4. A great choice for a great price.

Quality RF, Great Audio, Metal bodypack. Short Version: Great RF performance, audio is amazing with the preset EQ turned on, the bodypack is sturdier than expected . These are fantastic! I use the Shure PSM300 (with the good metal body packs) and various Sennheiser units on a regular basis. I bought a few PTM-22 units for my personal rig, and they have been just as reliable as our Shure and Sennheiser units. I got the S4 and took it to a gig Sunday night expecting it to perform the same as all the others. I hooked everything up, and it was. However, I poked around in the menu and turned on the EQ function, and that was a game changer! It seems like just a high frequency boost, but it made all the difference. Before our first song of rehearsal was over I already had my mix dialed in, and it was the best IEM mix I’ve had in all my years of gigging. I was planning to put this in my wireless rack and only use it for events I’m engineering, but now I want to keep it in my backpack and I never want to play without it!

Solid affordable IEM unit. The S4 is a solid wireless in-ear monitoring system that is both reliable and budget-friendly. This system includes four bodypack receivers and a complete rack mounting kit. I had the opportunity to thoroughly test the S4 over the last few months, both at home, during rehearsals, and live performances. I've had a positive experience overall
