Hello Jumble, In all honesty I'm not 100% sure . My husband has an Experia phone (not the M2) and the speaker works very well with this phone. I would suggest you contact the seller to check comparability but personally I think it will be fine as this speaker will work with any Bluetooth handset.

Hi there. I am not sure, but if your devices have Bluetooth, then they should be able to connect to the speaker. Even if they don't have Bluetooth, you can connect any device with a 3.5mm headphone socket on it to the speaker using a 3.5mm Stereo Jack Plug to 3.5mm Stereo Jack Plug.

The instructions say it can. I haven't tried as it's connected to my iPad. But when it was linked to my phone, when I typed a text you could here it through the speaker.
