Bose SoundLink Flex (2nd Gen)

Scored on 112 verified owner verdicts, from 821 comments read across 2 communities
TL;DR
Opinion on the SoundLink Flex 2nd Gen turns on a firmware update. It added a loud startup and shutdown chime that cannot be muted or turned down, startling owners and waking people at night, and it removed things owners relied on: voice battery announcements, cycling Bluetooth sources from the button, and stable stereo pairing. Longer-standing complaints sit underneath, with batteries draining while the speaker is off and degrading inside a year or two, bass thinning above about three quarters volume, and sound arriving lopsided from one side. The reason owners bought it still holds: warm, punchy bass and clear highs for the size, better again with two paired in stereo, and strong value at sale prices.

43% of 112 verified owners recommend the Bose SoundLink Flex (2nd Gen), based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

The headline score reflects owners (Reddit, enthusiast forums), independent lab tests, blogs with no affiliate links, and YouTube owner-comments when they line up with owners. YouTube is shown for perspective but kept out here — hover the i for why.

What owners like
  • Surprisingly punchy, warm bass and full-bodied sound for such a compact, portable size · 9 · 8%
  • Paired in stereo mode, two units deliver noticeably better separation and fuller sound than a single speaker · 7 · 6%
  • Strong value at typical sale prices ($25-$100), often called a steal for the sound quality delivered · 6 · 5%
  • Battery reliably lasts all day (10+ hours) for owners who use it regularly outdoors or at work · 6 · 5%
  • In-app EQ adjustment is praised as a genuine upgrade that lets owners tune bass, mids, and highs to taste · 5 · 4%
What owners flag
  • A firmware update added a jarring, loud startup/shutdown chime with no way to disable or lower its volume, repeatedly startling owners and waking people at night · 20 · 18%
  • Recent firmware updates stripped away features many relied on, including voice battery announcements, cycling Bluetooth sources via the button, and stable stereo pairing/connections · 10 · 9%
  • Battery drains even while powered off and degrades within 1-2 years, sometimes failing to hold a charge at all · 8 · 7%
  • Bass is noticeably weak or 'petering out' at higher volumes (above ~75-85%), especially compared to rivals like the SoundLink Mini II or Tribit · 6 · 5%
  • Sound comes lopsided from only one side of the unit, a build issue several owners independently noticed · 4 · 4%
Who it's for
A great fit if
  • Buyers wanting a small, portable speaker with surprisingly punchy bass for its size
  • People who'll pair two units for stereo sound, widely praised as excellent
  • Casual listening at the gym, terrace, hotel room, or camping trips
  • Budget shoppers grabbing sale or refurb units, seen as a great deal at $50-100
Look elsewhere if
  • Anyone sensitive to loud, unmutable startup/shutdown chimes, a widespread firmware complaint
  • Heavy daily users worried about battery longevity, with recurring reports of fast drain or early failure
  • Speakerphone or party-volume use, where call volume and high-volume sound quality disappoint

Common problems & things to know

Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.

Redditⓘ good to know

“Updates are coming model by model, and the country is also important. Wait a few more days, maybe the update will arrive. Bose said they would bring it to all Soundlink devices by the end of March.”

Redditⓘ good to know

“This is a friendly reminder that the SE is different from a regular sound like Flex. It doesn’t have a microphone to talk to, but the sound levels are all the same, which is why this one is cheaper.”

Redditⓘ good to know

“The source device needs to be Snapdragon Sound certified in order for any aptX codecs to work with Bose products. It sucks this isn’t clearly outlined.”

Redditⓘ good to know

“I have two soundlinks both are manufactured on may 2025, still one is updated and for the other one, there's no update showing, now i can't pair them.”

Redditⓘ good to know

“That's the update, apparently. One minor inconvenience is that I can no longer get the speaker to tell battery percentage by holding power button.”

Redditⓘ good to know

“I called Bose. That annoying sound is there apparently so that the user knows the speaker is turned on. Despite the flashy lights, and the voice prompt giving you the battery level, Bose thinks that annoying sound is what tells us the speaker is turned on.”

Redditⓘ good to know

“Today I updated to version 8.2.16, some things improved, some things got worse. The startup sound is still different, but it's followed by a hissing sound, so it's only slightly weaker. The Bluetooth connection sound, however, is fine, not the classic BOOM.”

Redditⓘ good to know

“In the app you can fine tune bass/ trebel and got a parametric EQ”
