The construction is entirely plastic - but as long as you dont throw your headphones around or in your bag, they should be sturdy enough. Really run big as,most feedbacks said. The rubber life ring works great for putting it on their wrist so they dont loose it. Molto belle e ben fatte. Unless one is using their app on the handset, the sound quality of these is actually mediocre. Snug and comfortable , wish it was wider in the back but it covers the ears ok. Budget gear is sexy. Super light weight and very comfortable! I was happy to find a pair with dark soles so that I can wear them outside and they still look good! Everything feels quality with these booty slippers, and I feel like these would last many years.
