Compatibility - It has a cable adapter so you can plug into a computer or into a phone. But if its worth the price difference is up to you. It fits great and is very secure. They are wide and they are so lightweight. When I opened the package of my Comply Professional Noise Isolating Earphone Tips my heart sank. Great new style and excellent quality. Other than that, this has been money well spent. From setting up the bluetooth to explaining basic use, the manual (1 page) was clear and extremely simple. Very comfortable and durable. Der Bass wird nie megapräzise sein aber er reicht tiefer runter, als ich ihm zugetraut hätte, wenn man seine schiere Menge etwas zurückgefahren hat.
