SHIDU Voice Amplifier, Wireless Voice Amplifier 10W Rechargeable Portable PA System Speaker with UHF Wireless Microphone Headset Support MP3 Play for Teachers, Yoga, Tour Guides, Outdoor Trainers

I bought it to help an elderly married couple communicate with one another. She had lost strength in her neck and could no longer hold her head up, but talked softly into her blouse! He had hearing aids that couldn't compensate for her problem. After some experimentation we got used to the system and were pleased with its clarity, volume and performance. He carries the speaker around with him, so she only has to worry about keeping the mike close to her mouth. The microphone arrangement was very comfortable for her, but the battery seemed to run out by mid afternoon if the system had been in constant use. But in our experimentation, I was glad to note that small auxiliary rechargeable batteries could be attached to the units, recharging them even while they were operating, which I hoped might be an acceptable solution for the battery problem. I don't live near them, but the last I heard they were still happy with the system.

...wenn der Raum, der mit der eigenen Stimme 'beschallt' werden soll, nicht zu groß ist. Ansonsten ist die Lautstärke in ausreichendem Maße einzustellen. Was jedoch schön wäre, wenn auch die Tonhöhe einstellbar wäre. Der Lautsprecher hört sich etwas blechern an.Für gelegentliche Nutzungen völlig ausreichend.

I have purchased this product a few times over the years. So I am familiar with its excellent quality. But unfortunately now, the headset size seem too big for my head. I am wondering if we had the option of choosing a size which I had missed?Now using my older Shidu set's headset.
