The black Shure ULXD6/O is a digital tabletop transmitter equipped with an omnidirectional boundary mic and compatible with ULX-D and QLX-D receivers. The omnidirectional polar pattern provides 360° pickup, allowing several speakers at a small table to use a single mic. The unit's low profile is ideal for applications such as video-conferencing where minimum visibility is required. A smart choice for situations where wired mics are impractical, this tabletop transmitter enables quick setup and tear down, and can be put away in a docking station (available separately) for storing and charging when the mic is not in use.
With rugged, yet lightweight plastic housing, the ULXD6/O transmitter delivers pristine 24-bit/48 kHz audio quality and RF performance over its entire 330' range. It offers AES 256-bit encryption for secure transmission and advanced rechargeability options, making it suitable for use in large meetings at conference and convention centers.
User-Friendly Features in a Low-Profile Housing
- The mute button can be configured for momentary or push-on/push-off operation and features a bicolor LED indicating the mute status.
- The unit quickly syncs with a wireless receiver via infrared at the touch of a button.
- The high-pass filter reduces low-frequency noise caused by table vibrations or air-conditioning systems.
- A power lockout function disables the power switch and prevents accidental changes during events.
- 1/10/20mW selectable RF output power allows you to increase either the transmitter's range or the number of mics operating simultaneously.
- Low latency makes the ULXD6 ideal for meetings that require live sound reinforcement.
- The transmitter is compatible with the full line of Shure's antenna-distribution components.
Convenient Power Management Options
- The unit operates for up to 8 hours and 40 minutes on two AA batteries.
- An optional Shure SB900A lithium-ion rechargeable battery pack offers intelligent power management with over 9 hours of battery life, precision metering in hours and minutes, and zero memory effect.
- A USB port allows for docked battery charging with the SBC450 (4-bay) and SBC850 (8-bay) networked charging stations (available separately).
- The charging stations enable remote power monitoring via Shure's Wireless Workbench software.

Sturdy but uncomfortable
Color: Black
The seat itself is sturdy and easy to put together, I’ve now had the product for 8 months and had no issues wear/tear despite nearly daily use, but… it’s not comfy, at all. The seat cushion has a texture to it that scrapes at my legs if I don’t have an extra pillow on it or am wearing shorts. Additionally, the seat pillow is just kind of hard. It doesn’t give very much at all, so if I sit on it for more than an hour or two at a time my butt starts to get really sore. It works as a budget option, but invest in a good seat pillow if you plan to sit in it for any length of time.

A chair that does the job
Color: Black, Color: Black
I’m really happy with this chair overall. I wanted something comfortable, sturdy, breathable, and spacious enough for long hours at my desk when I work from home, and this chair delivered. I’d easily give this chair five stars because it exceeded my expectations in comfort, quality, and overall value.
Comfort and Support
The mesh back keeps it cool and comfortable during extended use. One of my favorite features is the adjustable lumbar support. You can manually position it exactly where your lower back needs support, and it fits the curve of my back perfectly. It provides great support without feeling too firm or uncomfortable.
Build Quality and Design
The chair itself feels solid and well-built. It doesn’t creak or make noise when shifting around, which makes it feel stable and high-quality. The seat is roomy and comfortable, and the overall design looks clean and modern.
Easy Assembly
It also came with an instruction manual that was extremely simple to follow, and assembly was very easy. I was able to put the chair together by myself in about 20 minutes without any help.
Armrest Functionality
I also like the armrests. They aren’t adjustable by height, but they do flip all the way up, which is surprisingly convenient. You can easily slide the chair under a desk or use it as an armless chair when needed.
Packaging and Presentation
Another thing worth mentioning is the packaging. Everything arrived extremely well-packed. Every individual part of the chair was wrapped securely, including bubble wrap protection for the components. The hardware and accessories were neatly organized, and the chair even came with the necessary tools for assembly in case you don’t own a drill or tool set. The presentation and packaging were excellent and showed real attention to detail.
Overall Impression
Overall, this is a fantastic office chair for the price: comfortable, supportive, sturdy, easy to assemble, and packaged exceptionally well. I’d absolutely recommend it and would confidently give it a five-star rating.

Solid quality and comfortable
Color: Light Grey, Color: Light Grey
Wonderful quality chair, solid and sturdy, it was easy to put together, the directions were very clear and all the pieces fit together perfectly without issue. It is made of breathable material and I love that the arms flip up easily. You can raise it up or down and it has an adjustable headrest. It also has adjustable lumber support. It rolls easily and the color is the only reason I might return, I think I want a different one instead. The chair is comfortable for a petite person but equally comfortable for a tall person. We have both in our family and it is great for both. The armrests are comfortable and there is really nothing negative to say about this chair at all. Considering the quality, it is a great value for the money.

Comfortable and easy to set up
Color: Black, Color: Black
I’m happy with this chair. It was not hard to assemble, and it feels stable after putting everything together. The mesh back is comfortable and breathable, so it doesn’t feel too hot when sitting for a while. The seat cushion is also thicker than I expected and feels soft enough for daily use. I like the adjustable headrest and the back support, especially for working at a desk. The chair looks simple and clean, and the wheels move smoothly. Good value for a home office chair.
