Could not get rear speakers to work properly despite following instructions step by step. 5 leaves me with plenty of room - I could possibly have even tried the 8 but I like loose shoes. 5, ordered the 8. It seems like the screws that come with them are too long. They can truly take cold feet that have refused to warm up, otherwise, and take you to where you want to be with comfort. Supporting micro SD card can be great for storing songs. Techmaster PEB ? BassgasmChris Stapleton ? TravellerDonovan ? Beat CaféChristian McBride ? Live at TonicPink Floyd ?

This is probably the worst part about them because I always have to re-adjust the volume - THEY ARE SUPER LOUD ABOVE 60! I work from home and wear them everyday but the pairs I?ve purchased elsewhere typically take a full year before the fur/fabric on the slipper insole wears through. The more I type this review, the more my love for this keyboard grows.
