Phenyx Pro Plug-on XLR Wireless Transmitter Receiver System, Wired-to-Wireless Microphone System w/ 16 UHF Frequencies, Auto-Scan, XLR Microphone Adapter for Both Dynamic Mic and Condenser Mic (PTU-X)

I am a huge Phenyx Pro fan. I discovered their products several years ago and have 5 or 6 of their wireless products, so it was an easy decision to pick up this wireless XLR adapter. For starters, the box contains 1 wireless XLR transmitter, 1 wireless XLR receiver, 1 double-headed charging cable, and 1 carry bag. First impression out of the box is that the PTU-X is built sturdily and does not feel like most other budget products, where external casings are often made of cheap plastics. The items came with a charge so I was able to test the syncing function right away, and I must say I am mostly impressed. After turning both units on via the power button, you push and hold the sync button on the receiver, and the unit cycles through available channels and selects the best one available. Next, press the sync button once and hold the transmitter up to the receiver face-to-face, and the two sync, and you are ready to go. This process, though easy, does provide what I feel is the biggest opportunity for improvement. I found that it can take up to 3 attempts to get them to sync. I would say that almost 50% of the time they do sync on the first attempt. I tested the process 10 times and found that it connected on the first try 5 times, on the second try 4 times, and once on the third try. I am a pretty patient guy, so this doesn’t necessarily bother me, but this could be improved upon. The transmitter does provide +48V phantom power at the push of a button and has a mic/line switch so you can select the best noise reduction option for how you are using it. Others have mentioned the tabs at the end of the receiver being in the way, which I also experienced, but found it pretty easy to remove them if you have a small hacksaw; just make sure to be careful not to damage the rest of the unit. This was the other thing that I believe could be improved upon. I am a wedding DJ so I took the opportunity to test the unit out after setting up for a wedding this weekend. I’m not going to risk having a problem that could ruin a moment in a wedding on an untested product, but once I was set up and had some time before the wedding started, I was able to take advantage of the big venue and give it a good test. I compared the PTU-X system plugged into a standard SM58. I can’t say I was surprised that the unit works great because I use several Phenyx Pro wireless products. That said, I was pleasantly surprised at the range and clarity the PTU-X provided. The max I tested at was about 75ft, but at that range, I experienced no signal dropouts or distortion of any kind, even when I was not in line of sight. Overall. Very happy with the PTU-X by Phenyx Pro, and I am excited to see if I can use it to wirelessly connect a satellite speaker. Would 100% recommend this item and may buy more if the speaker experiment works.

I’d heard great things about the Phenyx Pro Plug-on XLR Wireless Transmitter, and it absolutely lived up to the hype. As someone who’s constantly on the lookout for dependable wireless solutions—whether for microphones or satellite speakers in larger venues—this unit instantly impressed me. Right out of the box, everything you need is there: the transmitter, receiver, USB charging cords, and even a convenient carrying bag. Setup was a breeze. I paired the transmitter with a wired mic and the receiver with a speaker, then took a stroll about 50 feet away—no dropouts, no interference, just clean, solid audio. The labeling is clear and helpful. The receiver has distinct buttons for Power, Channel, and Sync, while the transmitter includes a +48V phantom power option and a Mic/Line switch—super handy for flexibility with different gear. The sound quality? Excellent. Crisp, clean, and professional. No noticeable latency. This isn’t just a budget-friendly wireless option—it’s a serious tool for performers, presenters, and audio techs alike. I’ll be putting this system through its paces at my next live event, but after this initial test, I’m feeling confident. If you’re looking for an affordable, high-quality wireless XLR solution, this is it.

Operationally the product works pretty well - connectivity is straightforward, battery life is acceptable (3.5-4.5 hours), and sound quality is good (transmission is digital so no compression or artifacts). However, the device is quite wide at 1.25 inches. With that amount of width, you can't plug multiple devices into consecutive channels on a standard mixer. If you plug a receiver into channel 1, you will not be able to use another in channel 2, etc. This is true on my Mackie, Yamaha, and Behringer mixers. So, if you have 4 xlr inputs, you'll likely only be able to use 2 devices. I'm still debating return over the issue. Also, it's pretty heavy; consider this if yours will be handheld during use.
