A pretty good sound quality headphones but the volume and bass a little low on a Sandisk Clip (and Sandisk Zip). This can be arranged with headphones amp (FiiO etc ...) if you like more volume. The bass are also underrepresented. A helmet too 'flat' for my taste but not 'colored' either. The volume button is a little more. Comes with a nice pouch (nothing else). Unpacking is a bit much (be patient!). No other included accessories. Very fast and flawless dispatch by Amazon.
