Bose Speaker Audio Cutting Out — Fix Guide

What Does This Error Mean?

Move your phone closer to the speaker — most Bose audio cutouts are caused by Bluetooth signal loss from distance or interference. If the phone is already close, try disabling Wi-Fi on the phone temporarily, as 2.4 GHz Wi-Fi can interfere with Bluetooth.

Affected Models

Bose SoundLink Flex
Bose SoundLink Max
Bose SoundLink Color II / III
Bose SoundLink Revolve / Revolve+
Bose Portable Smart Speaker

Common Causes

Bluetooth signal interrupted by distance, walls, or obstacles
2.4 GHz Wi-Fi router interfering with Bluetooth
Multiple Bluetooth devices competing for connection
Phone moving in and out of range in a pocket or bag
Outdated firmware causing audio buffer issues

How to Fix It

Move the phone within 1–2 metres of the speaker.

Bluetooth has a maximum range of about 10 metres in open space, but walls and other 2.4 GHz devices dramatically reduce usable range. Start at close range to eliminate distance as a cause.
Turn off Wi-Fi on your phone temporarily.

Wi-Fi (especially 2.4 GHz band) and Bluetooth share overlapping frequency ranges. If audio stabilises with Wi-Fi off, switch your router to 5 GHz band to avoid the conflict.
Move other Bluetooth devices away.

Multiple Bluetooth devices nearby compete for the same radio spectrum. Turn off Bluetooth on devices you are not using to reduce interference.
Update the speaker firmware.

Open the Bose Music app → your speaker → Settings → Software Updates. Firmware updates often include Bluetooth stability and buffering fixes.
Forget and re-pair the speaker.

On your phone, go to Bluetooth settings → forget the Bose speaker → re-pair from scratch. This clears any corrupted connection profile that may cause intermittent dropouts.

When to Call a Professional

If audio cuts out consistently within 1 metre with no interference nearby, the Bluetooth antenna may be damaged. Contact Bose support.

Frequently Asked Questions

Bose speaker cuts out every 30 seconds exactly — what causes that?

A regular interval cutout is almost always a power-saving feature putting the source device's Bluetooth to sleep. Check your phone's battery optimisation settings and exclude the Bose app from any auto-sleep rules.

Audio cuts out only in one room — is the speaker broken?

No — this is interference, not a speaker fault. That room likely has a Wi-Fi router, microwave, or baby monitor running at 2.4 GHz. Move the speaker or switch your router to 5 GHz.
