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.

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.

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 really wanted to like this unit, and I really gave it a try, but I still continue to get heavy distortion when I use these in my band. So I'm a sax player and anytime I turn up the volume just enough to hear myself, I get a horribly distorted sound coming back at my ears. It sounds so bad, I can't use it. For comparison, and live on the gig, I've swapped out a Behringer P2 vs the NUX B7PSM, and the sax always sounds great on the Behringer P2. As soon as I use the NUX, I get that horrible distorted sound. I've tried it with a variety of outputs too: from the phone out on a mixer, phone out on the TC Helicon voicelive, so the XLR out with an adapter and always the same problem: distorted sound all to hell. It just can't take the sound of a saxophone, or a trombone for that matter. I loaned the unit to my bone player friend on stage and she immediately took them off her head saying "they sound like shit!" I agreed.Now, I'm giving it 2 stars because I have found them to be quite useful inside my zoom meetings. The sound is better than bluetooth and more reliable with less latency. I just need to make sure to use the extension cable and get the unit away from my laptop, because it kills the Wifi. Since I missed my return window, I've found a good use for them there.1/5 stars for monitoring a brass instrument2/5 stars for use as a wireless headset for zoom

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.
