I emailed the company about this issue and this is what they said:"Thank you for your email, yes, you are right, we have a earlier version of the black earphone, actually these two version earphone are mostly the same, the only little difference is that the old version earphone size is a little smaller than the new version, we made a little change for the size, because we received many feedback that the size is too small for most of customer, so our engineer changed to a little larger size for the I have now worn them for three workouts and find that they are a solid shoe. So far it works well and keeps the bike mostly in place, I?m a bit paranoid about it since I have had a kayak fall from the top roof of the car when I was driving once. I went to use the headphones and when I placed them on my head one of the two mounting arms that are on either side of the speaker cone snapped in two. I followed the directions exactly and tried many times but it just would not pair with my Bluetooth headset. Not worn constantly as I have 2 other pairs. Color que pedí5. I felt that this is really a waste since it only stayed for 2 days and falls off in the middle of the night while we are sleeping so we thought someone was inside out house. They feel nice and crisp to me. Bear in mind that if you lose even one of the eartips, you have to buy another set from hyperx for £5 which is slightly expensive for 2 bits of rubber.
