The in-ears are well made (as would be expected at Monster) and provide as promised a very good sound (especially in the category Bass, I think). The design is adapted to the Lumia 800; therefore fits together perfectly. The function keys volume, track selection and taking calls or start voice recognition poses few problems with Windows Phones. For other Nokia devices only does answer calls with the supplied adapter; generally should also work with non-Nokia devices, but is not guaranteed by the manufacturer. The in-ear wearing well, and do not fall out (there are six different sizes ear pads for plugging in). All in all I am very satisfied!
