I thought they are sending each 5 different colors but only red came, ob my ... Rubber is very harder than I expected. Little bit smaller than formal large sized tips. Quality is good for most of TWS but still narrow to fit in battery case. Most of wired headphones(earphones) suitable for 3.5 to 5mm radial of nozle.
Rather on the small side, ordered L. Quality is good. Sound is good.
Really like the quality. Good fit good sound.
