Bose SoundLink Flex (2nd Gen) review

With the release of the Bose SoundLink Flex (2nd Gen), we couldn’t help but notice its striking similarity to the original Bose SoundLink Flex that came out in 2021. Now offering “Big, bold sound” compared to “Clear sound with big bass” in the same durable, outdoor-ready package, we’re curious to discover what is actually new. In this Bose SoundLink Flex (2nd Gen) review, we reveal whether it’s worth the upgrade.

Editor’s note: this is the first version of the article. Updates will follow as the market changes.

What’s it like to use the Bose SoundLink Flex (2nd Gen)?

The Bose SoundLink Flex (2nd Gen) looks very similar to its predecessor. From its identical shape, size, and weight to the same loop attachment, it takes a closer look to see what’s new and improved from the original Bose SoundLink Flex. This new generation is still wrapped in a durable rubberized finish with a metal speaker grill and features an IP67 protection rating, making this speaker both dust and water-resistant; Bose also states it’s still drop-proof and rust-proof. Safe to say, the new SoundLink Flex (2nd Gen) is still ready for your next outdoor adventure or poolside hangout.

Aside from slightly larger feet on the back of the enclosure to help with stability when using the unit as an upward-firing speaker, the most noticeable design difference is an updated and redesigned control strip. In an attempt to make some controls easier to find and operate, the SoundLink Flex (2nd Gen) features a control panel further recessed into its enclosure, with a now isolated, easier-to-find power button. There is also a new dedicated Play/Pause button, and they’ve added a status light above the shortcut button as well.

Still, as with the original, the buttons feel slightly mushy and require a heavy finger to ensure your command has been registered. It’s not quite the instant, satisfying, tactical click you get when controlling the JBL Flip 6, for example. Lastly, the Bose SoundLink Flex (2nd Gen) is available in a few new colors. Our test model spots the Alpine Sage finish, but it’s also available in Sandstone, Blue Dust, and, of course, classic Black.

Should you use the Bose app for the Bose SoundLink Flex (2nd Gen)?

It’s important to note that the new SoundLink Flex (2nd Gen) uses a different app than the original. The original SoundLink Flex uses the Bose Connect app, while the 2nd Gen uses the Bose app.

The Bose app has a few useful features; otherwise, it’s pretty lean. Casual listeners could get away without installing it. It offers minimal EQ options with four rather uninspired presets (Bass reducer/booster and Treble reducer/booster). Luckily, you can tweak the sound via the supplied Bass, Middle, and Treble sliders. Still, while a three-band customizable EQ is certainly better than nothing, considering some other companies offer a ten-band EQ, it would be nice to personalize the sound of the SoundLink Flex (2nd Gen) speaker a little further.

The Bose app also lets you pair a second SoundLink Flex (2nd Gen) speaker for stereo playback. Unfortunately, since the SoundLink Flex (2nd Gen) relies on a different app than the original, this means you cannot pair a 1st Gen SoundLink Flex with a 2nd Gen for stereo performance. Here, you can also customize your shortcut control (choose between Speaker Link, Voice Assistant, and Spotify Tap). I don’t find the shortcut control particularly useful, especially if you only have one speaker. When assigned to Voice Assistant, you still have to push the button to activate it, just as you would on your phone. Perhaps it may be helpful if you find yourself closer to the speaker than your phone, but not so much on day-to-day operation.

Lastly, the app can sync the SoundLink Flex (2nd Gen) with current Bose Smart Speakers or Smart Soundbars. Using the “SimpleSync” feature, you can extend the reach of your home audio system and share the audio between your two speakers, for example.

How does the Bose SoundLink Flex (2nd Gen) connect?

The Bose SoundLink Flex (2nd Gen) offers multipoint connection and connects to your devices via Bluetooth 5.3, a welcome update from the original SoundLink Flex, which connects via Bluetooth 4.2. While it supports the standard SBC and AAC codecs, Android users with the right phone can access higher-quality sound. The SoundLink Flex (2nd Gen) now features Snapdragon Sound and will automatically stream music to a Snapdragon Sound-certified phone using the aptX codec.

How long does the Bose SoundLink Flex (2nd Gen)’s battery last?

We don’t see any battery life improvement with the SoundLink Flex (2nd Gen). Bose advertises a playback time of 12 hours off a single charge, the same playback time stated for the original SoundLink Flex. This is on par with most portable speakers of this size. Of course, battery life depends on a few factors, like your EQ settings and overall playback volume. For example, Bose says you will only achieve 3 hours of playback if your speaker is at maximum volume.

If you want to squeeze as much playback time as possible out of your speaker, you’ll want to keep your volume reasonable and, unfortunately, choose an EQ setting with minimal bass. The harder your speaker has to work, the more battery it will use.

How does the Bose SoundLink Flex (2nd Gen) sound?

Comparing the SoundLink Flex (2nd Gen) side by side with the original SoundLink Flex, without any hardware upgrades to the 2nd Gen, I’m not surprised to discover that it sounds identical to the original. This isn’t necessarily a bad thing. However, both speakers can benefit from some minor EQ tweaks.

In its stock form, the SoundLink Flex (2nd) provides a relatively safe amount of lows, mids, and highs. It isn’t the most exciting-sounding Bluetooth speaker out of the box. Listening to “Subdivisions” by Rush, the odd-time signature synth bass intro is slightly quieter than I’m used to, and I know there is more detail to be heard in Neil Peart’s intricate cymbal work. Fortunately, it’s a quick fix. Diving into the three-band EQ to increase the Bass to +6 and the Treble to +3 makes all the difference. Switching genres, “Tech Noir” by Gunship also benefits from these adjustments. A more satisfying, pulsing low-end from the kick drum, combined with better clarity in the layers of vocals and swirling synths. Overall, a more energizing and detailed listening experience.

While I’m usually the first to complain about a lack of EQ options, let’s remember the SoundLink Flex (2nd Gen) isn’t designed for critical listening. It’s meant to enhance the vibes of your next gathering, whether you’re camping in the woods or simply chilling on the front deck. A quick tweak of the EQ easily provides enough low-end power to keep a small outdoor gathering going, but you won’t be rattling any windows with it. Cranking it up past 80% volume on my phone, the DSP kicks in to reduce its bass frequencies to keep the whole unit from distorting.

Should you buy the Bose SoundLink Flex (2nd Gen)?

The Bose SoundLink Flex (2nd Gen) is a quality outdoor Bluetooth speaker that’s durable, portable and offers decent sound at a reasonable price, just like the original. If you already own an original SoundLink Flex, there’s no need to rush out and buy the 2nd Gen. Without any significant hardware upgrades, or better battery life for that matter, if you’re a casual listener, you could snag an original SoundLink on sale and most likely be happy with it.

Fortunately, it appears Bose recognizes these updates as minor. The SoundLink Flex (2nd Gen) is the same price as the original, $149.

What should you get instead of the Bose SoundLink Flex (2nd Gen)?

For a few dollars less, consider the JBL Flip 6 ($99 at Amazon). This durable, portable speaker is also ready to take on the great outdoors with the same IP67 protection rating and shares quite a few of the same features as the SoundLink Flex (2nd Gen), like a three-band customizable EQ, stereo pairing with a second identical unit, and decent battery life.

Alternatively, you can check out the Anker Soundcore Motion 300 ($79.99 at Amazon) for almost half the price. It offers a very similar design to the SoundLink Flex (2nd Gen), right down to the loop attachment and EQ change when you switch up the speaker’s orientation. While heavier than the Bose unit, it offers stereo playback and LDAC support if you’re keen on Hi-Res audio for your adventures. Lastly, it’s outdoor-ready with an IPX7 protection rating and a drop-proof, durable build.
