The straps feel tight right out of the box, but they loosened up within hours of wear. Perfect for travel or gym or anything else fits lots of clothes can fit some shoes . These run a tad we big I?m a size 8 and ordered a medium about an inch to big Also the seller has free shipping and free returns Other sellers do not offer that another reason I bought from here! Have used this product on my Birkinstocks for decades and it does truly prolong the life of these shoes. (Makers like Sennheiser ,AKG, and yes Beyerdynamic) Headphones competing of àt this level this could set you back twice as much as the T90. Definitely worth getting if your kid has moved away from training wheels! Its just what I wanted Overall they are good earbuds but like I said the battery life on these are not to the point that it does not last 5 hours before it says batter low. I use these to listen to audiobooks and music.
