The electronic side is okay, about what youd expect for this price range. I think its micro switch has broken and I am sad about it. Sure its a bit wider than my G502 but just doesnt feel right, the hump is maybe set too far forward and not actually in the palm area where it should be. Lovely quality, nice and cosy. Just got these , so far , I love the packaging and they work great, BUT my experience has been with other products , one headphone will fail or low battery is common , so I?m hoping these work snd last! Im pretty impressed over all for their wear and comfort after all the "running" I put them through chasing 1st graders. So, I have one of those Peloton Bikes and extremely happy. Daughter needed this to charge her calculator and has been using it from day one of purchase. Certainly feel the extra sweat and work on the belly during workouts. As some reviews said they run large, which is perfect if you are a half size like myself.
