We have had them for several months, and they have held up well so far (but are only used maybe 1-2 times per month for orchestra). If youre looking for the bluetooth dongle, its in a little velcro pocket inside the carry case. Amazing service with no extra cost to myself. Always remove the head shell and cartridge for transport, you wont regret it. You dont feel it at the top of your head at all (and Im bald). ?AND THATS SAYING SOMETHING! Até o momento, só alegria.

While Bluetooth, they also include an HDMI cord so if it dies you can still listen.
