If you're serious about your music and looking for something to use with your BlackBerry, then the new Loewe Speaker 2 go is well worth a look. I first learned about this at a press event in Italy back in April, and now it's gone on sale here in the UK I've had the pleasure of spending a little time with one. The full review is over on iMore, so I'm not going to duplicate it all here, but it's worth highlighting a few things.
Because the Speaker 2 go has NFC support built in, pairing your BlackBerry 10 device is pretty straight forward. It uses Bluetooth to stream the music, so you can also pair it the old fashioned way if you need to. This isn't an impulse purchase item either. It costs £269, which is a lot, but it also delivers a pretty stunning sound. You can also charge your BlackBerry battery right from the USB port on the back, and use it as a speakerphone when you're on a call, though that experience is less impressive.
The full review has a more detailed look, but I've been using this quite a lot during the past couple of weeks with Easytune on my BlackBerry Z10 and the experience has been faultless. It's a lot of money to spend on a speaker, but I know I want one.
