Listening to music of a portable audio device, etc.

You can use the speaker by connecting a portable audio device, etc., to the speaker using an audio cable (commercially available).


  • Before establishing a connection between the speaker and a portable audio device, turn down the volume of the speaker and the device to avoid any sudden loud sound output from the speaker.
  1. Connect a device to the AUDIO IN jack with an audio cable (commercially available).

    For connection, use an audio cable with a stereo mini plug (no resistance)*1 at both ends.

    *1 If you use an audio cable (with stereo mini plugs) with significant resistance, the sound may be lower. Therefore, make sure you use a cable (with stereo mini plugs) without resistance.

  2. Turn on the speaker. *2

    The(power) indicator lights up in green.

    *2 If a BLUETOOTH device that has previously been connected with the speaker is located nearby, the speaker may be connected automatically with the device. In such a case, the (BLUETOOTH) indicator on the speaker lights up in blue.

  3. Turn on and start playback on the connected device.
  4. Adjust the volume to a moderate level on the connected device.

    If the volume is adjusted by operations on the connected portable audio device, the(power) indicator on the speaker will not flash.

  5. Press the –/+ (volume) buttons to adjust the volume.

    When you press the –/+ (volume) buttons to adjust the volume, the (power) indicator flashes once or 3 times.


  • When you cannot hear the sound, raise the volume on the connected device.

  • If the BLUETOOTH connection is active between the speaker and a mobile phone (smartphone/iPhone) via HFP/HSP, you can use the hands-free function while listening to music of a portable audio device, etc. that is connected to the speaker’s AUDIO IN jack.


  • If you connect an audio cable to the AUDIO IN jack, the output from the device connected to the AUDIO IN jack has priority, and you will not hear the sound from the BLUETOOTH device. The(BLUETOOTH) indicator lights up or flashes in blue to indicate the BLUETOOTH status. Absence of sound from the BLUETOOTH device does not indicate any trouble with the speaker.

  • Even when the audio cable is connected, you can switch to the BLUETOOTH mode on “Sony | Music Center,” and listen to music from the BLUETOOTH device connected via a BLUETOOTH connection.

  • When connecting a portable audio device to the AUDIO IN jack and playing music, you cannot use the buttons on the speaker to perform operations such as pause, skip to the beginning of the next track, and skip to the beginning of the current track.

  • Do not use the AUDIO IN jack in a place where water may splash. The supplied AC adaptor as well as the USB port and the AUDIO IN jack behind the cap are designed neither for waterproof nor for dust proof.

  • Be sure to close the cap completely after disconnecting the audio cable from the speaker.

    The cap plays a very important role in maintenance of the waterproof and dust proof performance.
