They don?t cost much and the sound reflects that. 5 but the 8 fits perfectly! Incompetence and laziness. I then ordered size 5 out of desperation and somehow they fit me perfectly. I get so many compliments! With the memory foam tips on the Life P2 are not chargeable as they dont fit in the charging case but without the memory foam tips the sound was thin, unimpressive and the earphones are no where near as secure in your lugoles. I loved it it?s durable however I could not get the top part of the avocado to stay on. I soon got used to them, and I now find them very comfortable. By the comments someone said these were Too big! These are super warm, almost too warm.
