The Sony SRS-BTM8 Portable Bluetooth Speaker (Black) is a wireless stereo sound system that's small and lightweight for portability. It's equipped with dual 50mm drivers for great on-the-go sound. If you're looking for a speaker with a wireless connection option, you won't be disappointed. Pair this speaker with Bluetooth wireless devices and enjoy your tunes from up to 30' away, without the need for any cords. The speaker is also compatible with Near Field Communications technology (NFC). This allows you to align the NFC logo with the logo on another NFC compatible device in order to turn the speaker on, activate Bluetooth, pair the devices and start streaming your music. You can also connect any device with a standard 3.5mm line out to the speaker.
If you get a call on your phone while listening to music, simply hit the speakerphone button for hands-free conversations. The speaker runs on four AA rechargeable batteries, which afford up to 20 hours of playback. Or, you can connect it to AC power using the included adapter when you're using it around the house. One more sure sign of portability is a handle -- and the Sony Portable Bluetooth Speaker has one on the top for easy carrying.
