Quad-Channel Wireless in Ear Monitor System, Mono IEM System w/ 4 Bodypacks, 4x25 UHF Frequencies, Rack Mount, 164 ft Range, Wireless in Ear Monitor for Bands/Studio (PTM-33-4B)

The Phenyx Pro PTM-33 is by far the BEST budget wireless IEM system that I have used to date. I’m the worship director of worship team for a small church that averages in about 50-60 members per Sunday for our one 11am-1pm worship service. Before using the Phenyx Pro PTM-33 we were using a super budget 2 channel 250 dollar wireless IEM system with 6 wireless receivers sharing two channels. Needless to say as a band we were more or less dealing with it more than we were actually happy with it. We had more than occasional dropouts, the sound coming from the receivers were not only so quiet that the system needed an additional purchase of an amp to be usable, but they also were extremely treble heavy and left a lot of lower frequencies completely lost in the mix. We were always trying everything in our power to get more of our lower frequencies to come through clearly on these and just ended up dealing with it because at least we were able to somewhat hear ourselves despite the quality. Fast forward to the beginning of 2023 when I decided it was time to go wireless with our mics and ended up choosing the Phenyx Pro PTU-7000A which we were absolutely amazed by. This made me curious enough to get the PTM-33 wireless IEM system. Hooking this system up was a dream. I was actually late the day I decided to hook the new system up, panicking, thinking I wouldn’t have the time, but thank the Lord for how easy setup was. I had it out the box, connected to our system and ready to go in 5 minutes flat. Due to the ability to make a daisy chain connection, I literally only needed one wire from the system I already had and a couple spare short wires that I had sitting around to connect every channel and back out into the original system we were using. I couldn’t dream of it being any easier than this! The size of the transmitter was absolutely perfect as well, being not much bigger than the system and amp we already had. I think the only thing that would probably make me happier for the setup process was if there was an auto-scan option for every channel just like on the PTU-7000A to search the RF environment to locate better available frequencies with more precision than just randomly looking through and praying its a perfect channel. REGARDLESS, we experienced ZERO dropouts throughout our stage and sanctuary. Heck, I was able to go to the bathroom and not miss a beat of the sermon because the signal reached all the way out to our bathroom by the entrance of the church building while our transmitter sat on stage. As far as the sound quality goes, I will say the one thing I was not pleased by was the In-Ear Monitor earpieces that came with the system. These were the only thing I would say was not good with what came with the system. They were about as useful as a pair of airplane earbuds if they actually had silicone tips. They were a bit tinny, and didn’t have much depth or soundstage in my opinion. They also offered zero noise isolation, I could literally hear everything else going on around me clear as day. I may be being a little bit harsh, but I’m spoiled with much better sounding earpieces. I could hear everything, but it was definitely not enjoyable and made me glad that my band all had their own IEM Earpieces. I’d say use the included earpieces if you don’t already own your own and are still waiting for your new earpieces to come in. Definitely look into companies like KZ, CRA, Moondrop, and Salnotes for great IEM earpieces for under 25 dollars as replacements for these. HOWEVER, when we used our own IEM earpieces, WOW the sound was so much fuller than what I was expecting. On our old 250 dollar setup, my band would want to constantly take their IEMs out of their ears because they didn’t like the sound that came out from the transmitters, but the PTM-33s outperformed and exceeded all of our expectations. The sound was much fuller in the mid and low frequencies while the high frequencies were just right for vocals and especially with the treble coming from the crash cymbals as well as the snare. The bass that was drowned out on our old system was fully there and in our faces but not offensive. Now my band wears them even off-stage because it sounds so good. Suffice to say the battery life on these are doing way better than what I’ve used before. No noticeable drainage after I had the receivers on for practically the whole day with sounds constantly flowing through them. No complaints whatsoever on that end Last and my most favorite thing about this set are the clips on the receivers. NO MORE are the days of broken receiver clips for your waist and pocket! These clips are SO STURDY. Don’t EVER expect the clips to break, or for any of the receivers to fall off while you’re using em or even jumping around because these clips are so strong and sturdy. Conclusion/TL;DR : Score : 15/10 The PTM-33 is an excellent budget IEM system that can measure up to even some of the top names in the game. PHENYX PRO KNOCKED IT OUT THE PARK WITH THESE! Easy-to-use, set up, and has amazing sound quality, range, and battery life. They’ll stay on your waist and pockets and never fall off with its SUPER STURDY high quality receiver clips. Just make sure to purchase new IEM earpieces and try not to use the included ones.

I'm using this in a Church auditorium (clear line of sight) along with cordless AT cordless mics for our worship band. When looking into IEM there are three tiers. Very cheap, prosumer and pro. Don't waste your time or money on the very cheap. The financial jump from prosumer, which is what I would consider this unit, to pro is huge. This unit worked perfectly for us. The 900hz range is no where near our wireless mics therefore we have no interference or connection issues. The sound quality with good IEM headsets is good. The headphones that come with this unit are good for testing, but not what your musicians will want. This unit accepts stereo inputs but sends out a blended mono signal. That is fine for most people and bands. It also has a loop out which other units in this price range do not. The unit is of good quality for this price point and we have been very pleased. The pacs will auto connect to the unit for easy setup. Having tried other units in this price range I would highly recommend the Phenyx pro.

I've purchased 2 of these units. One for personal band use gigging out and one for my church. They work well. Minor hiss/fuzz (comparable to Sennheiser unit baseline self noise). As long as the antennas don't have a lot of barriers to the signal they don't cut out and if they do it's for no more than a moment. The audio quality is suitable and clear. No notable loss of eq spectrum. Occasionally the lcd screens cut out or don't display levels properly but it doesnt affect the signal. The build quality is sufficient. It's thinner metal but metal none the less. The IR syncing is great. I recommend these to anybody looking for wireless IEM's outside of highly professional use. They're great! I bet they'd be even better with a larger antenna on a distribution system.
