We've always been a bit skeptical of portable DAPs like the Sirius S50
and Samsung neXus
that promise to let you listen to sat radio content on-the-go, because since neither device includes a built-in satellite receiver, you're stuck with the programming you've recorded while the player was docked at home. PC Mag seems to agree that this class of gadgets offers rather limited functionality, and their review of the neXus isn't very promising for potential customers: unless you buy the $70 car kit for listening to live feeds in your ride, you're basically spending either $219 or $269, respectively, for either a 512MB or 1GB MP3 player that delivers neither great sound quality nor an acceptable battery life. What's more, you have to make sure that you keep the unit docked for at least eight hours a month so that XM can properly authenticate your subscription to keep your recorded tunes from disappearing. Ultimately, unless you're a on a tight budget and absolutely need some XM swag in your pocket at all times, PC Mag suggests -- and we tend to agree -- that you're better off shelling out a few more bucks for the Pioneer Inno
or Samsung Helix
, which both allow you to pick up and record live feeds right out of the box, no dock necessary.
