Questions about Sony SRS-XB100

Yes, the Sony SRS-XB100 can be connected to two devices at the same time, but there are some limitations to consider: - The SRS-XB100 supports connection with two Bluetooth devices at the same time, which allows two users to maintain a connection with the speaker. - However, the speaker can only play music with one device at a time. So if you have two smartphones connected, only one of the devices can control the music playback. This allows for flexible use, but music playback can only be controlled by one device at a time.

No audio output. USB is the only socket on this device. I would like to take this opportunity to say that I am very happy with this speaker. Excellent sound quality and super light.

Hello, The SRS-XB100 can be charged via the USB-C port. Please use a commercially available USB power adapter with an output power of 5 V / at least 0.5 A.

Although the Sony SRS-XB100 has a USB-A port, this is not used for playing music from a USB stick, it is only intended for charging the battery via the USB-C cable included in the scope of delivery. Here is a link to an alternative: Technaxx Musicman Ma (4 h, mains operation, battery operation)

This depends more on your phone and it’s configuration than the particular speaker. Most often you hear every sound (incl the ring from the incoming SMS) on the speaker if it is not muted for notifications. In case you have bluetooth headphones or a car, where you can connect your phone, you can test it and the behaviour with this speaker should be comparable.
