CUT THE CORD. BE IN COMMAND!

The NUX B-7PSM is a wireless personal in-ear monitor system with automatic RF environment scan, 5.8GHz interference-free broadcasting frequency, and 24-bit / 40 kHz high-quality STEREO audio transmitting.

From any position. On any stage. Hear every note in detail with NUX B-7PSM in-ear monitoring system.

It quickly finds a clean wireless channel and automatically assigns it. The B-7PSM offers a super low latency of less than 5.5ms and has an operation range of 100 feet (30m) when unobstructed between the Receiver (RX) and Transmitter (TX). (The operation range is around 32 feet (10m) when obstructed). It's a super light-weight wireless, mini-compact system designed to clip on & go. The TX features a 1/8" TRS plug (you can use the included adaptor to convert to 1/4"), broadcaster-grade audio via 5.8GHz digital transmission to the compact RX. The RX's clip design can easily fit to your shirt, belt, or guitar strap. And, with our newest automatic frequency hopping technology, B-7PSM is reliable and stable while you perform on stage.

The user-friendly matching system makes it easy to use, just turn ON both wireless units (TX & RX), then it will be paired within a couple of seconds. Each wireless set has a unique pairing algorithm, it automatically detects each other and configures their own IDs. The signal never interferes with any other wireless including the WiFi* signal.

 A Loud Stereo Phone Preamp.

Plug in the TX to a live or personal mixer and turn on the TX (LED indicator will show GREEN.) Then connect your in-ear buds with the RX, turn on the RX to pair with the TX. The LED indicator will be solid GREEN. Now it's ready to go.

You can adjust the RX volume in 0.5db increments with the + and - buttons. The maximum volume is 0dB, and the minimum is -64dB. Holding down the + or - button can increase or decrease the volume quickly.

The B-7PSM offers STEREO audio transmission, so it's perfect to work with professional personal mixers to pan the tracks as you want on stage during rehearsals and live performances. The B-7PSM features premium sound quality with a 92dBA dynamic range and 20~19K Hz frequency response.

 

While the B-7PSM is a STEREO IEM solution, you can use it in a mono environment as well if needed. Simply use a 1/4" MONO to 1/8" STEREO adapter (to split the mono signal from a 1/4" Output into both channels of B-7PSM's 1/8" Stereo Input), then you can get a mono signal that can be heard in both the left and right channels.

*Recommended:  Please stay 2 meters (6 feet) away from the Wifi router for the best results.

Caution:  

1. Please consult the seller of your adaptor before making the connection, in order to avoid any device damage.
2. Caution:  Do not put the in-ear buds in your ears before you start to adjust the volume, it may hurt your ears if the volume is too loud.

Note:  

1. When coupling multiple B-7PSM systems, please turn on 1 set first, pair it, and then turn on the other sets sequentially.
2. For best results the TX should be at least 1 meter above the ground, 2 meters away from Wi-Fi routers and wall or metal surfaces to minimize reflections.
3. We recommend you use headphones or in-ear buds with a 16~32 Ω impedance for the best experience.
4. B-7PSM is designed for band rehearsals and live performances, prioritizing the best possible STEREO experience. You'll enjoy the product and the experience it provides, while it may not be suitable for personal silent practice.
5. Short press the power button of the RX to return to the default volume setting. It may be too loud if the in-ear buds are very sensitive. Please turn down the mixer's volume and increase it carefully.

All-around thumbs up!
Size: 934W-Z, Color: Black
So far, so awesome. Easy to assemble, comfortable, arrived quickly and is exactly what I was looking for. I have a tall work bench in my new studio so I needed a chair that we could allow me to sit higher than a regular office chair and allow me to get off my feet after standing on the concrete floor. Plus its a nice looking chair that I am sure will last a long time. I love the flip-up arms and the lumbar support. This is just right!

Perfect Balance of Comfort, Support, and Style!
Size: 934-Z, Color: Black, Size: 934-Z, Color: Black
I’ve been using this chair for a few weeks now, and I’m genuinely impressed with how much of a difference it’s made in my workspace. The mesh back is one of my favorite features—it offers excellent breathability and prevents that sticky, overheated feeling you sometimes get with solid-back chairs, even after sitting for hours. The seat cushion is firm enough to give proper support but still has enough give to keep me comfortable through long workdays. It feels like the perfect middle ground between soft and supportive. The adjustable foot ring has been a complete game changer for me. I use a taller desk setup, and having somewhere to rest my feet makes a huge difference in posture and overall comfort. Whether I’m sitting upright for focused work or leaning back to read, it’s always at the right height. The flip-up armrests are another smart design choice. When I’m typing, I like to have them down for support, but when I’m done, I can flip them up and push the chair neatly under my desk—saving space and keeping things tidy. The casters roll smoothly on both hardwood and rugs, so I can move around easily without scraping the floor or getting stuck. The overall build quality feels solid and sturdy, with no wobbles or creaks. Assembly was surprisingly quick—everything was clearly labeled, the parts felt durable, and it only took me about 20 minutes from opening the box to sitting in the chair. The sleek, modern look is another big plus—it blends in perfectly with my home office décor without feeling bulky or taking up too much visual space. If you’re looking for a chair that combines comfort, ergonomic support, durability, and style, I can’t recommend this one enough. It’s equally great for work, studying, or just relaxing at your desk, and it’s definitely been worth every penny.

OK for the price, but overall comfort is avergae
Size: 934-Z, Color: Mustard
Easy to put together, color (mustard) accurate to images, and while I understand this is not a high-end chair, I feel like it still needs to be rated for its quality. Pros: the seat cushions are fairly comfortable and it rolls well. Adjustable footrest is easy enough and mostly sturdy. Cons: For a tall office chair, it doesn't go up high enough. I actually had to lower my standing desk to sit at it, which then isn't where I want it when I'm standing now. It's also a bit wobbly. The seat area's attachment to the post isn't as solid as it should be for a tall chair, so while sitting, it does tend to lean/slope forward and wobble side to side. The lumbar support is not adjustable, so I'm not even really sure what it does. And the armrests are not very comfortable to use. Since they are hard plastic, they are just a bit too rigid to rely on for any comfort. They are basically there to hold on to when you're getting out of the chair.

Good Value for a Tall Chair
Size: 934W-Z, Color: White
I have received this chair just today and would like to give my first impressions of it. Height is super adjustable as well as the foot rest. My desk is very tall (~34 inches vs standard ~29 inches) and does not suit a standard height chair. This chair's height is enough to sit comfortably at mybut also still having adjustment to be even higher. Lumbar support is a manual adjustment that can be adjusted by sliding the lumbar piece up or down and it seems it can be tiled as well. No reclining feature or slight backrest tilt adjustment. I'm used to my chairs reclining so it feels a little awkward siting in a flat base and straight backrest. I feel like I'm sitting too forward or leaning forward slightly but is probably something I can get use to. Easy to put together and feels very sturdy. Plastic parts of chair are made from a really sturdy plastic, like playhouse plastic materials. Wheels roll around carpet easily. Mesh seems to be a strong material, though the mesh feels kind itchy on bare skin. Overall, I think this is a good chair to get if you're needing a tall chair for a good value and can sacrifice no backrest tilt.

Excellent value for money!
Size: 934W-Z, Color: Black, Size: 934W-Z, Color: Black
I absolutely love this office chair! I needed a chair that could support my standing desk without sacrificing comfort, and this one completely exceeded my expectations. It's incredibly sturdy and durable, well-made, and the height adjustment is super convenient, making it easy to find the perfect fit. Even during long hours of work, the seat is comfortable, and the ergonomic design effectively reduces pressure on my back and legs. I love its clean, modern look—it fits my home office perfectly. Assembly was quick and easy, and for this price, the quality is absolutely fantastic!
