Are they totally perfect headphones ? No. They hold all kinds of different bottles and theres plenty of room between them you can easily identify whats where. TOTAL FAIL! I have almost lost my buds on 2 occasions from it being on my Keychain and just it opening while Im walking. So cute I love it 😍 see well balanced. I take a size 5 in women, and my feet are on the wider side. Now I need to wait a whole week to start training and again it hasnt even shipped yet. Excellent quality as always from fitflop. I also know that chicken wire material can often be cheap and fall apart or bend easily.
