NUX B-7PSM 5.8 GHz Wireless in-Ear Monitor System, Stereo IEM,Charging Case Included, Stereo Audio transmitting, Designed for Live Shows and Band Rehearsals,not Suitable for Personal Silent Practice

If you read the reviews on this IEM there are a lot of people saying how poorly it performs, that it is very noisy. I purchased it for use in a band situation with other vocalist and guitars. After receiving it, I tried using it connected to just my guitar and it was noisy, I was dismayed. I contacted NUX directly questioning this issue. My question “ Is there an explanation why it will work in a performance or rehearsal situation but would be noticeable in a silent practice session “ Their response. “Ugly facts: The system is a stereo and wireless setup, meaning that the raw data size is double that of a mono wireless in-ear monitoring system. To ensure a stable connection, we compress the raw data to some extent, resulting in a slight loss of sound quality and occasional high-frequency distortion. This distortion is more noticeable when using the system for quiet guitar practice sessions. However, it performs exceptionally well in live performances and band rehearsals where multiple instruments are mixed together, and the distortion issue is significantly reduced. “I have since used it with my band and it works really terrific. I did not notice any noise, It is so small and light, and was a pleasure to use, much better than the speaker monitors.

First off I was totally excited to use this product, but buyers beware you will be totally disappointed that you wasted $200 on this item. When I plugged this unit into my Focusrite interface and got a constant fuzzy static and distortion sound while playing guitar. I tried different audio sources with all displaying the same results. I would not recommend this product to anyone and I will be returning this product.

It states that you get over 4hrs of run time on a full charge. However, I'm a DJ and I used it in full volume and I got about 2.5 hrs. Connectivity is great with no drops and unnoticeable latency. My only quarrell is the run time. I was hoping to get over 4 hrs in full volume but that is not the case. The sound quality is OK. It's not as full as I had hoped. I can totally tell the difference when I unplugged my IEM and plugged in directly to my mixer. There was a big difference in volume and sound quality. If you're OK with that, then I would recommend this unit (specially it's on 5.4 GHZ). But if you're a DJ like me and doing weddings and events, then I would NOT recommend it.

I've been using the NUX B-7PSM Wireless in-Ear Monitoring System for several weeks now, and it's been a game-changer for my performances. The low latency of less than 5.5ms and the operation range of 90 feet are indeed impressive, but I've found that the range can be reduced if there are obstacles in the way. The automatic RF environment scan and clean wireless channel are great features that have saved me from interference issues. However, I have experienced some minor signal dropouts in noisy environments. Overall, the system is lightweight and easy to use, and the unique pairing algorithm makes setup a breeze. I appreciate the broadcaster-grade audio via 5.8GHz digital transmission to the compact RX, and the RX's clip design is convenient for attaching to my clothes or guitar strap. While the NUX B-7PSM Wireless in-Ear Monitoring System is not perfect, it's definitely a reliable and stable option for musicians looking to upgrade their on-stage monitoring.

If you remove all frequencies except low ones on the equalizer, then strong sound distortions and clicks are heard (does not depend on the sound source that was used). It is possible that there are distortions at other frequencies, but they are not so noticeable. to be clear. I decided to keep this device because my measurements correspond to the manufacturer's specifications and the device may be useful. and this level of distortion is expected due to the prioritization of latency minimization over sound quality. but I want to warn that this device is not suitable for everyone. in my case, I prefer to use a wired headphone connection whenever possible.

I bought the NUX B-7PSM's when they first came out because they are 5.8ghz which was rare at the time. My experience with them has been ok. They've never failed me in a practice or a gig. They are noisy. I like how they add that to the item title now because they are noisy. 5.8ghz works great. The charging case is handy. Cheap plastic leaves a lot to be desired. I've taken very good care of mine and they've never been dropped. However, the power button on the receiver body pack pushed into the unit and can't be retrieved without busting the cheap plastic unit open. There are plenty of equal if not better options out there for a fraction of the price nowadays. Hopefully, NUX comes out with a better version because I'm a NUX fan boi. Just not a fan boi of these pricey but noisy and cheap plastic things.

This product is an excellent solution for musicians, performers, and anyone who needs a reliable wireless monitoring system. The sound quality of this system is exceptional. The stereo audio transmitting provides crystal-clear sound, with no interference or signal dropouts. The in-ear monitors fit comfortably and securely, and the sound isolation ensures that you can hear every detail of your performance. The charging case is also a great feature. It is compact and easy to carry, and provides up to 6 hours of use on a single charge. The LED indicators on the case and earbuds make it easy to see the battery status, so you can always be sure that you have enough power. Another great feature of this system is the 5.8 GHz wireless transmission. This frequency range provides a stable and reliable connection, with low latency and no signal interference. It is also easy to set up and use, with no complicated menus or settings to navigate. Overall, I highly recommend the NUX B-7PSM 5.8 GHz Wireless in-Ear Monitoring System. It is a high-quality product that provides excellent sound quality, reliable performance, and convenient features like the charging case. Whether you're a professional musician or just someone who wants a great wireless monitoring system, this product is definitely worth considering.

I desperately wanted to love this product. The materials, functions, storage case, and overall look are fantastic. Unfortunately, the sound quality is absolutely awful. There is an always present static noise that will not go away. I tried every combination of volume and gain settings on the monitor system and source audio, but could not get the hiss to go away. I read the other reviews that claimed this and I really wanted them to be wrong, but in the end I had the same experience. I'm genuinely sad that this was the case, beside the sound quality, everything else is great about these. But, for an IEM system, sound is all the matters.

Funciona excelente y se conecta de manera inmediata muy recomendado

The product is very good regarding the charging case and compact form and battery. But the sound is very bad and noisy. It is little noticable during YouTube or Spotify playback. But during recording, there is a clear buzzy sound which is there. Each stroke of guitar or similar instrument creates more buzzy fuzzy sound which is verymuch annoying. I need the form factor and there is no similar product available at this price, that why I won't return this item. The company should work on the buzzy sound.

This is fantastic for gigging musicians. It can be plugged directly into a unit such as a hx stomp or (with the appropriate adapters) into a mixing desk or XLR on stage to the desk. I use with in ACS in-ear monitors and the sound quality is great. There is no interference like I used to get from my U Vive, which broke after about a year anyway. The fact that you charge the transmitter and receiver in the case is brilliant, as once the case is charged you can get a quick boost whenever needed. Highly recommend this!

Tolles Konzept. Bei mir im Setup allerdings zu viel Nebengeräusche.

I read all the bad reviews and bought them thinking I would possibly be sending them back but what a surprise - they are outstandingly good. The only problem I can foresee is the fairly short charge - I will have to remember to turn them off between sets or I may even buy another so I can use and charge all night long. (I do a total of 1 3/4 hours on stage playing but I am there for up to 4 hours) but well worth it for the excellent sound quality.
