The Tribits are very lightweight, fit comfortably and snugly in the ear, and do not feel like theyre going to fall out if I shake or tilt my head. So, please, BE CAREFUL with it. I started writing this review in a very positive light. Doesnt stretch much. They don?t offer half sizes so I ordered an 8. However, the hook of the velcro is positioned far lower such that the variable ajustments are not possible. Good quality wood and finish. Ich hatte diese Schuhe für meine Tochter in der Größe 24 bestellt. Scalpy boi Preis-/Leistungsverhältnis für die Soundqualität ist mangelhaft.
