MeeAudio do a bunch of cheap earphones, plus some not quite so cheap, like the Pinnacle P1’s, which have the big advantage of using MMCX fittings, meaning you can have them wired, using a 3.5mm Jack, or buy aftermarket cables with either a Lightning plug or a USB-C, or MeeAudio’s own Bluetooth cable that connects both earpieces with a cable going around the back of your neck with the battery on one side, and the remote on the other, to balance them.
They also come with a wide range of eartips including my favourites the triple-flange ones, which once you become accustomed to fitting them give pretty good passive noise reduction, great sound, and they do not fall out!
I’ve got two pairs of Pinnacles, one pair has a cable with a Lightning connector, the other pair the BT fitting; to be honest, I prefer the wired connection, you get proper Lossless playback, (if you download tracks), whereas BT just cannot handle the bandwidth necessary.
But at least there’s a bunch of options available with one basic earphone design. I’ve been using them for a few years, and they’ve always been reliable and they sound superb.
