so I've had them since last week, and have mainly used them around the house. Being wireless without having to plug in the receiver is so convenient.
I play through a digital modelling amp (Peavey Vypyr VIP 3) and created some mightily f/x heavy sounds, and there is no noticeable latency.
I've A/B'd them with a lead (OBBM) and there is no noticeable loss of signal or volume.
I just used them straight away with the charge they had from the factory, and they finally died at band practice last night. Nothing slow or intermittent about it, one second was fine, the next they were off. Well the transmitter anyway.
Because of it's position under the guitar I could not see what if anything, happened to the power light.
I'm gonna charge them tonight for the first time, and take them to an audition I have tomorrow.
Initial verdict is I'm loving them, but I need to see what they are like at gig volume, and also I want to find out if the power light gives some kind of low power warning.
