Works with Sony Xperia Andoid 5.1.1 without any problems! Can only recommend the part warmly, sounds brilliant!

I have had the 1st version of the Soundlink for just over three years and was thrilled from the first test, in a large market. My children each have a version II of the device described here and are also completely satisfied.
You should always be able to try out an audio device first!
The Soundlink II can play Bluetooth with the audio codecs SBC Standard, no APTx or AAC. It doesn't have WLAN or NFC either.
I listen to almost 100% MP3 and can't tell the difference between Bluetooth and cable. But I appreciate the handiness of the Soundlink. It's almost always with me, on holiday, at work, in the bathroom, in the kitchen.
Changing the Bluetooth source has become much easier with version II.

works with various devices from different manufacturers without any problems.

I have listened to music with at least 10 different mobile phone models and different operating systems and have had no problems so far.

Runs perfectly with Nexus 6P, Android 7. Super sound. Totally satisfied.

With a Samsung Galaxy Note 4 (Android 5.1) and a Samsung Galaxy S3 (Android 4.4) there were not the slightest problems,
