Size 37 measures just under 9 inch. Item was double boxed for safety. After putting hair care, skin care, jewelry in pouches and hair dryer, curler etc. I thought this s2 would be better but its not in my opinion. Doesnt take up a lot of room like other 3-way chargers. (De no querer hacerlo permanente, un tape adhesivo doble cara funciona a la perfección)Realmente recomiendo el producto! All is now right with the world. However the strap broke kinda easy. Ive been using this model of headphones for over 8 years and have the say they are simply the best headphones ever created in term of sound quality for price, I personally dont even mind the genuine retro look. Over all still good quality.
