Put them on and I picked the right size for me. Good product prompt delivery No more Tevas for me. Please for your own sake look for a different set of boxes So while I worry about losing these, I dont really worry about breaking them. A bit of tugging and rearranging with thumbs and you?ll get it into the right place. The sound and microphone quality is excellent and far better than what I was expecting for headphones in this low price range. More so than Samsungs but it doesnt allow wireless charging, they are not as well built and they lack other niceties but for many it would probably be all the wireless headphone they need at a quarter of the cost. Entrega rápida y puntual. The aircraft noise almost completely disappears.
