I absolutely love the brand, but not this pair. The plug is 1/4 inch, so be aware that you will need an adapter if the headphones are used with a device having a smaller audio connection. However, the V1 is nothing like my previous wide shoe (2E) purchase. They engulf your feet like a fuzzy blanket! On the whole, it seems well made, KMC packed it well, with a card thanking me for purchasing and showing me who to call if I had any problems, which I appreciated. Slip on. Kindly go for this product if u r into sports or gaming The sound quality on the earbuds themselves (the speakers) is good, if not a bit too bassy. My feet are painful, especially first thing in the morning and these slippers are heaven! They are supportive, comfy and durable.
