  • Clear voice, good amplification, good microphone and battery life.
I will say this is a good device and works pretty well BUT it is a bit heavy though. I assume this is because of it's big battery capability. That being said, there is a shoulder strap that it comes with BUT it is kind of thin and does not have pads on it so it makes it a bit uncomfortable to wear for long periods especially with the weight of this device. This is something that you can carry regardless. There is a handle that is a bit more padding but still is annoying to carry for long periods. Regardless the device is quite powerful for amplifying sound especially at events and such. First thing I will say about it is that the microphones are not too bad. They are light weight and connect easily. The microphone does an okay job at wind guarding on the microphone. You are able to avoid excess noise on a windier day. The battery life on this device is not too bad. It last for several hours and you are able to use this while it is charging. It does get a little warm so try not to have it direct sunlight on hot days. You can control the volume and carry it with you as you talk. I think moving around does not hinder the sound quality. It is very loud so great for outdoor events where you do not have access to power for a big microphone. This is not like a concert microphone so be aware of that but it gets the job done. It last for quite sometime which is nice. The actually amplifier is quite sturdy and well built. It is not something I would drop even thought the casing is pretty sturdy. It may actually dent or crack. The front is a kind of metal mesh so it gives good sound and has a bit of durability. You can plug in directly to the amplifier in order to work. The plug is okay and the wire is just your standard USB kind of cable so do not expect anything super sturdy. The sound I could not really measure in decibels but it can be pretty loud and clear. There is no feedback or crackling. In a small amphitheater it actually was able to be head by everyone. Overall this is a good device to have if you are planning to do events and such. It really does a good job projecting your voice while also making sure that no surrounding noise makes it to the amplifier. The color is nice and it is well built. I do wish the cables provided were of better quality but the microphones are not bad. The battery life on these is not bad and it stays connected well. I also wish the shoulder strap had some more padding. The controls are pretty straight forward. It is easy to use and learn. ... show more
