He installed it quickly and he likes it If you have a similar purpose and you are not expecting some soft cloud of air to walk on, then these may be for you. Each cord also has its own little velcro tie-back attached so you can easily coil it up and velcro it to your preferred length or hold it secure for traveling. The cups fit my bigger ears nicely - but if its really hot you may feel it after a while - but only when its quite hot. Buy these if you need replacement tips. It also has a built in ear pod charging port. 5mm will prevent most stereo jack from entering completely. **This is nothing against the seller** I really wanted these! The earphones have a pleasing aesthetic and look like a quality product. Ive loved the cork sole through the years.
