This has to the be the find of the decade! The device beats all the portable mic/amplifiers I have purchased over the years. The device is well made and was easy to pair. The headset and microphone is adequate for my use. Could be a little smaller. However, not too cumbersome. The volume is very loud for audio playback and speech. As a straight MP3 player it doesn’t reproduce enough bass. The belt clip, micro SD card slot and the echo dial put this device over the top. Excellent overall item. I’m tempted to buy another one just for keep sake. Excellent overall??I finally received this beautiful voice amplifier. It's my first ever amplifier. At first I received a wrong version but SJS-us responded professionally and send me the right one 2 days after they contacted me. Kudos to SJS! This beauty is very loud and clear for its small size! I will use this more as my portable karaoke machine! It has 6 modes to choose from so there's no dull moment as far as functionality is concern. The wireless headset mic that comes with it blows me away, so easy to pair in no time and sounds loud and amazingly clear. I highly recommend this to everyone for professional or personal use.The unit works well but the sound quality is not the best. It is a little too tinny, could do with a tone adjuster.The speaker is decent and the sound quality is pretty good too. The mic is well designed comparing with the price. The only drawback I feel is that when you recording the bluetooth is disconnected and you have to use another mic to capture the background music with your own voice.Overall, a nice box for casual users.This is my first time buying a Bluetooth Speaker. It is really amazing, it works well, connected to Bluetooth real fast and the sound is great. I can even connect one more microphone to it and enjoy singing karaoke. Highly recommended!!Perfect for work home or beach, blue tooth to your phone and jamMy grand children really like it
