I ordered the size 10 womens because all the reviews said to order up so I wear 9 1/2 so I got tens. The metal pieces have some tiny imperfections and some of the small metal grates on the shelves are not welded very well, look weak and one of them is broken a little. The micro portion is just a tad bit too large to fit into the headphones. I really cant find any weaknesses. La pecca di questo modello e la cattiva ventilazione dovuta al mancata traspirazione del materiale impiegato. Not the best quality of sound, but perfect for a mostly sound cancelling cheap headphone for school. 🤞🏽😍 I had 2 in my last house installed on inside of cabinets. Very confused at this time. This can also tune in AM/FM as well as connect to a device via bluetooth.
