And it is not really rising the volume anymore.We just got this about a year.Update:I found out that the battery of the headset is too weak. So that it is not working anyway I opened it in the hope to replace the battery. This is not possible.Shortly after the loudspeaker itself died. Used it a bit for my laptop to get a better sound.Really sad. Spent so much money and it did not even last a year. Stay away from it. ### ⭐⭐⭐⭐ Useful but necessarily handy. *by O***A on Reviewed in Canada on 3 November 2020* I bought this in the hope it would be useful to converse with others without putting too much strain on my voice. So far it has proven satisfactory under the right conditions. I have only used it as a voice amplifier and cannot speak to any of its other uses. The speaker itself seems rugged enough and has survived its share of tumbles from table tops and car dashes.My greatest complaint us the headset battery goes dead fairly quick and takes too long to recharge to be considered handy. Although it may be good for a forty minute presentation, it will not hold up for what I need it for. I may look around for a clip-on mike that is longer- lasting and a little less conspicuous.It would also be handy if it came with a carrying case to hold the various pieces. In these days of multiple rechargeable devices it's easy to get them mixed up when you're in a hurry. ### ⭐ EDITED REVIEW - FIRST CLASS SELLER *by E***E on Reviewed in Canada on 8 May 2019* I bought this to use at a couple speaking engagements to group of about 50 people. It would be indoors, and I simply wanted to have enough volume so my video camera would pick up my voice clearly. When I had fully charged the system and started using it, my son said that he heard me better without the device. Also test on video also indicated my own voice without amplification was better recorded. THEN THE MICROPHONE QUIT WORKING AFTER MAYBE FIFTEEN MINUTES. EDIT: Based upon my review, the seller contacted me and sent a replacement for free! Now That is better than any warranty!!!!
