Can I use my speaker with other manufacturer's devices?

Yes. You can use the speaker with any device that supports Bluetooth v.2.1 + EDR, Handsfree Profile 1.5, Headset Profile 1.0, Advanced Audio Distribution Profile (A2DP) and Audio/Video Remote Control Profile (AVRCP). You can also use the speaker with devices without Bluetooth, if they support audio output connection with a standard 3.5 mm audio connector.
