Hisonic HS122BT-HL Portable and Rechargeable PA System with Dual UHF Wireless Microphones & Bluetooth Connection

I am using this as a trainer and coach teaching and presenting at various client sites to groups of 40-50 people on average. This things rocks. It has an uncanny ability to fill a huge room with sound. The stick mic is as good as any I've used. The lavalier mic has great pickup but is a little light on bass, but works just great. The range of the stick is better than the lavalier transmitter, and the latter occasionally has a dead zone.I have used this is various rooms, and several times in a room 100 feet by 30 feet. Position it so it reflects off walls and you get erie coverage :)The bluetooth works perfectly, and yes you have to re-pair each time you power cycle it, but it takes but a second or two. All in all this is a great piece of kit that fits into the back of a Samsonite rolling office, and flies with me wherever I am presenting. It has saved my throat, and made for a much more polished delivery than shouting all day.Battery life is over 12 hours in all day use, and I have been unable to flatten a battery in either mic in a full day of use. I use 600ma 9v rechargeable batteries, but have also used standard 9v disposables all with the same results.

This is a great product. We use it in a room with up to 60 people. We have various groups using the room and they can operate it with minimal instructiions. The sound is good, and it is really nice to have the headset for the speaker, and the microphine to be used for audience participation, Both work well simultaneously. The batteries last many sessions. The main battery has an overcharge protection, so you can just plug it in and let it charge. The bluetooth works well, so you can play music from you cell phone. The unit has a 9v battery charger for the headset and hand microphone. However, 9v rechargeable batteries are difficult to find and are not recommended. So we just use the nornmal 9V disposable batteries, which, after probably 10 usings, are still running OK. Just keep a spare 9v battery in the case.

I started using this for doing talks and classes in rented spaces. It does a nice job at this; it has the volume to cover a good-sized hotel meeting room (capacity about 90 people) and allow everyone to hear me, even when I go into my quiet demonstration voice. I generally wear the provided headset and belt pack, so I never have a problem with the lavalier not picking me up which is common in cheaper 3.5mm connected lavaliers. The handheld also works very well, and being able to use them both at once is very good for situations like Q&A, where you want everyone to hear the question as well as the answer.Battery life is excellent. I generally charge it before leaving home, and I've used it as much as 12 hours in a 3-day period without needing to recharge. The headset and handheld last a good 4-6 hours on a commodity, no-name 9V battery which can be switched out in 30 seconds if needed. Bluetooth works simply, though it always makes a sharp, loud beep when connecting to your phone/tablet which can be annoying to your audience.Weak points: the carrying case is really bad; it's a bag with zero structure and no proper handle. It has side pockets that don't stay closed, that gap enough to let large items (like the handheld mic!) slip out, and still offer nowhere to store the headset. The wireless headset (really the belt pack transmitter, regardless of whether you use the headset or lavalier) is subject to interference -- I got bad static at a hotel conference room whenever I got within a couple of feet of the wall sconce lights -- and you really don't want to walk in front of this unit while it's on and you're wearing or carrying a live mic. That latter part may be true for all wireless systems.Overall, it's working well for me. I would buy another if I needed one, though I might look to see whether there's a version with two belt packs that can be used at the same time. I bought a second wireless headset and plugged its receiver into the 1/4 inch input to support a copresenter.

This has been a lifesaver !!! I officiate track & field and clerking it has saved my vocal cords .. I love the fact that you can use a mic, or headset or the lapel mic.You will be using up a lot of AA batteries but I try to shut the mic off after I have clerked in runners.

It just worked! Easy to set up. We used this for our wedding in a small 20 x 30 room. Everyone could hear clearly and no feedback noise. And having two seperate microphones meant that the officiant could leave the lapel mic on and pass the barrel mic around for other speakers to use.Remember to get the 9-volt batteries for the microphones. The rechargeable battery that it comes with is just for the speaker.

Couple of things... this is a good product, and a totally legit and helpful company that sells it as I had called them to ask questions and they were very helpful. I'm giving this 3 starts only as a heads up for people to not get any false expectations about the product. It works well, as described, the only issue is that it does have a bit of a very low "static" sound when using the microphone and there is no audio going through. That said, it is a low priced solution and serves a purpose if you need a microphone to expand sound. I got the model with bluetooth and that works well, except for the fact that you need to sync it every time you want to use if once you've shut the system down.
