Re: Why bother with the BT?
I upgraded to the BT wireless speaker when my trusty XMI X-Mini vacuum-capsule speaker - with 3.5mm jack plug - recently completely refused to do anything. Doesn't charge, doesn't light, doesn't emit sound. It is just outside the 1 year refund window. On Amazon the mini wired-amps get 4K positive reviews and several hundred "it just stopped working" with XMI not interested in the seeming 5% failure rate.
I'm sure I could shame my BT wireless speaker manufacturer into some sort of repair, should it also fail, and the cost/quality ratio impresses me more than the XMI.
