I recently bought a similar profile pair of ear buds, but those had the original one size fits all rest in your ear design. The arch support is absolutely amazing. The sound quality is even better than my old Skullcandy ear buds. I mainly use it for a daily work bag cus the speakers in my work truck SUX. This is a 5-star product! Compatible with all my devices. Not hard to put together at all. Great price for this rack. These are exactly what i needed, they feel very comfortable and when walking in the street i feel like im walking in slippers at home. I have attempted to use them on 3 separate phones.
