It worked OK except for the foam microphone windscreen constantly falling off. Overall great product & amazing sound quality- And using the amplification and aux can be tricky with all the volume knobs etc. El cable es doble, uno corto y otro muy muy largo. I’ve been wearing this waist trainer for 2weeks and I’m already seeing a difference in my waist! The battery life is great, they’ve seamlessly connected to all my devices (laptop, phone, and tablet), and they are pretty clear in playback. One feels like a slipper , the other like a boot . They were washed on cold water delicate, and delicate dry. Would buy from seller again! Great Christmas gift!
