The construction is on par to an inflatable boat! I ordered it and it came in two days later on Christmas Eve day. The battery life lasts for days. But for walking around the house, they kinda scare me. 5 and it fits her perfect theres few mm extra to grow but since its leather it will strech a little more overtime. I found my favorite bass thumping song and maximized the volume! But these are comfortable and light enough for around the house yet heavy duty enough for wearing outside or around the resort. I do love the extra headband on the headset, as it makes the whole thing feel much lighter on your head. Using an ipod, phone, or anything with a quality internal dac is all you need. Works perfectly with the Yeti X as advertised.
