My second set of Sennheiser MX 365 earbuds has now failed. That's the end of that brand for me; having two sets with the same defect (one side losing sound) is unacceptable. Plus I don't want to deal with trying to get an in-warranty replacement again, if they'd even allow a second replacement.
I thought it would be easy to find something this time around since I didn't need a right-angle plug (because the placement of the jack on the AGPTek player is more conducive to the usual straight-in plug), but it looks like the old-style type that don't go into the ear canal are a dying breed.
I ended up ordering
these ; the brand is unfamiliar to me, but the reviews are good.
