1 / 7Bose SoundLink Flex Bluetooth Speaker (2nd Gen), Black
Black: The Bose SoundLink Flex (2nd Gen) is a compact Bluetooth speaker for portable listening, with a claimed IP67 rating, up to 12 hours of battery life at typical listening levels, and orientation-aware audio. Battery life and volume experiences vary in customer feedback, so it may suit travel better than buyers who need sustained maximum-volume playback.
At a glance
- The manufacturer claims an IP67 rating for water and dust protection. Its description also says it floats, though that is not a substitute for following care guidance.
- PositionIQ is described as adjusting sound based on speaker orientation, including upright, laid-back, or hanging positions.
- Bluetooth multipoint is claimed for pairing with multiple devices. The speaker connects to the two most recently connected devices when powered on.
- The stated 12-hour battery life is for typical listening levels. The manufacturer states up to 3 hours at maximum volume.
- Linking a second compatible Bose speaker enables Party Mode. Stereo Mode requires a second SoundLink Flex (2nd Gen).

What to know before buying
Listing details to confirm
Battery duration is mode-dependent: the claimed up to 12 hours applies at typical listening levels, while the manufacturer states up to 3 hours at maximum volume. The listing details are inconsistent about mounting, describing a utility loop for clipping or hanging while the technical field says “No Mount.” The package list names a USB Type-C cable, while the title mentions USB-C without specifying the included cable's charging function. The technical details also list one required AA battery, which is unconfirmed and does not align clearly with the battery-powered speaker description. Confirm these listing details before relying on them.
Who is it for?
A good fit for
- Travelers and everyday listeners who prioritize a portable speaker with claimed water and dust protection.
- Buyers who want orientation-aware audio and the option to link another compatible Bose speaker.
- People using Bluetooth phones, tablets, or other listed compatible devices.
Less suited to
- Listeners who need long playback at maximum volume, given the stated up-to-3-hour claim in that mode.
- Anyone expecting standalone two-speaker stereo or a second speaker included in the package.

Customer feedback highlights sound quality, connectivity, and portability, with some describing the speaker as convenient for travel. Battery life and volume receive mixed reports, including comments that it may not play loudly enough or that volume drops very low. These concerns matter if you expect extended playback at high volume. The listing itself gives a shorter battery-life claim for maximum volume than for typical listening, but that specification does not establish the cause of customer reports.
Positive themes
- Customers praise sound quality, connectivity, and portability.
- Some customers appreciate the appearance and consider it worth the money.
Mixed feedback
- Battery life receives mixed feedback, with some customers finding it impressive and others saying it does not last long.
- Volume feedback is mixed. Some customers report it does not get very loud or that volume drops close to zero.
