JBL Go 5 review

For What Hi-Fi? readers at least, playing music directly from your smartphone may be the most cardinal of all cardinal sins. To take your music and subject it to being squeezed through your iPhone’s tinny little speakers is, to some at least, the equivalent of cooking a dry-aged steak in a microwave and then slathering it in a small mountain of ketchup.

This, in part, is why the JBL Go 5 exists. The fifth generation of JBL’s very affordable Bluetooth speaker is built to be almost as portable as your smartphone itself, but with boosted sonic capabilities that won’t leave your music sounding as though it’s been put through the metaphorical microwave.

The first JBL Go came out back in 2018, and since then, JBL has been steadily refining the line by adding more features, tweaking the dinky design and refining that all-important sonic output. The Go 4 was the former high water mark, but 2026’s new model is now on the scene – and, from what we’ve heard, this fifth-generation might be the best Go yet.

Price

You can all breathe a sigh of relief because, while the world’s financial markets may be in turmoil, some things are blessedly immune from inflation. The JBL Go 5 clocks in at the same price as its predecessor, once again costing a wallet-friendly £40 / $50 / AU$59 at the time of writing.

If you want something cheaper, your best bet is probably to plump for a now-discounted JBL Go 4, which can sink as low as £28 / $30.

There are a few comparable speakers knocking around at this near-entry-level price point. The five-star Tribit Stormbox Micro 2 tends to hover around the £45 / $46 mark; and you can now grab its successor, the Stormbox Micro 3 for around £63 / $65, although we haven’t yet tested that particular model.

Build & design

Unlike a former child star losing their chocolate box looks once they hit their troubled adolescence, the Go is just as cute as it has ever been. It’s a tiny bit larger than the fourth-gen Go, but the slight increase in size is perceptible only if you place the two generations next to each other.

Once again, we’re dealing with a very small, square(ish) speaker that is only slightly bigger than a pack of cards or a bar of soap.

Times have changed, however, so there are a few extra aesthetic developments beyond mere size. The Go 5’s front-mounted ‘JBL’ lettering logo has been rather cleverly hollowed out, so there should be less impediment to the sound from the driver reaching your ears.

Plus, JBL has added lighting to the party, which you can customise and switch on/off via the JBL Portable app. Twin strips of white lights run parallel across the top and bottom of the main speaker face, with four stock light themes – ‘Bounce’, ‘Loop’, ‘Switch’ and ‘Freeze’ – from which to choose.

Is it strictly necessary? No, of course not. Is it a fun touch for an ultra-portable speaker aimed at people who don’t want their portable audio taking things too seriously? Yeah, we’d say so.

Elsewhere, it’s much the same as before, and that doesn’t raise many complaints from us. Rubberised edging surrounds practically the entire unit, with large play/pause and volume controls housed at the top of the speaker and the power, Bluetooth pairing and Auracast icons spread vertically down the left hand side, all of which are easy to use and responsive to the touch.

At the bottom, JBL’s signature diagonally slanted ridges have been replaced by a rubberised bulge, but we don’t find that has much of a negative effect on how much the speaker grips to horizontal surfaces.

At the top right of the unit is a handy, non-adjustable carry loop, one that we find remains durable and robust no matter how many times we spin it around on an outstretched finger.

In fact, the entirety of the Go 5 just feels so well made that we’d bet a small chunk of cash that, barring a nuclear apocalypse or the battery running dry, it will last for many years to come. That IP68 rating means that an aggressive outdoor hosing leaves no lasting impression, and as our test sample(s) accompany us from the bottom of a backpack to the end of the garden, they take everything cheerily in their stride.

Features

Considering how small and cheap the Go 5 is, you’re not exactly starved of features. If you have the latest Flip 7 or Charge 6 speakers, many of the same features have been carried over to the fifth-gen Go, and there are even a few new tricks that are exclusive to the smallest member of the portable JBL family.

Check this out for a party piece: the Go 5 is capable of ‘AirTouch’ stereo pairing, and it really is exactly as described. Get two Go speakers together, tap them together end to end and, almost unfailingly, they’ll emit a chime of approval and form a stereo pair. You can also do this in the provided app, but what sort of fun is that?

Stereo pairing is easier than ever to set up and use, and the technology seems to have been improved since we tried it last. Our JBL Go 4 review griped that we would have liked slightly better sound synchronisation between our two speakers when playing in stereo, but we don’t now detect a noticeable delay from one speaker to the other when music is being shared by two speakers.

There’s a lot more packed into the teeny tiny Go 5. Auracast Bluetooth compatibility is back, bringing the Go 5 in line with the current JBL Flip 7, Charge 6 and new Xtreme 5 models and letting you connect multiple compatible JBL speakers together either via the on-unit button or via the JBL Portable app.

Battery life has been bolstered just a little, with the Go 5 squeezing out roughly eight hours of standard playtime, with an additional two hours via Playtime Boost. This is an increase over its predecessor’s seven hours of standard time and maximum of nine with Playtime Boost.

Do be aware that Playtime Boost should be seen as a ‘last resort’ option, as this feature will suck out most of the bass from your speaker’s output and make things sound unbalanced and rather thin. More of a ‘break glass in case of emergency’ kind of a thing if you desperately need to extend your power use.

Sound

JBL’s palm-sized Go 5 promises improved audio with a fuller, deeper bass than its antecedent, thanks in part to its 45mm driver and that hollow-contour logo working in tandem to “level up sound output and performance”.

“Level up” is a rather nice way to put it, and as we flit between the older-generation model and 2026’s fresh-from-the-oven fifth-gen iteration, it’s clear that this is the most sonically capable Go yet.

The Go 4 was a wonderful sonic surprise, but its successor does enough to trump it, treating us to a fuller, meatier reproduction that simply sounds more rich and engaging than its predecessor. There’s unquestionably more depth in the bass, too, though not to the extent that the lower end unnaturally dwarfs the rest of the frequencies and threatens to throw the entire reproduction off balance.

The Go 5 doesn’t try to do too much – instead, it gives us a hearty and surprisingly musical upgrade on anything that our tinny smartphone speakers could hope to muster. Relatively simple tunes, such Muse’s Madness, sound clean, composed and impressively clear through the midrange, while Turnstile’s crunchy rock anthem SLOWDIVE is dispatched with confidence and muscle as we shift things up a gear.

This is a speaker that can fit in the palm of your hand, yet it’s genuinely remarkable just how punchy and effusive the Go 5 is capable of sounding. Ludwig Goransson’s POSTERITY brims with energy when played via the JBL, and while this isn’t a speaker that will grant such a layered composition a huge amount of space, the feeling of rhythmic intent and cinematic drama comes through with real gusto.

Like almost all of the more recent JBL portables we’ve tested, the Go 5 is tuned to have an innate understanding of how your music should sound. Again, nothing here is overdone or overly coloured, but it shares its bigger siblings’ ability to go with the flow as we bounce around tracks and genres.

Is Nick Cave’s Avalanche the most well-organised and cinematic rendition you’ll ever hear? Of course not. Does the Go 5 capture the essential character of what Cave is trying to convey? Absolutely it does. Will bigger speakers offer more textural detail when playing Hans Zimmer’s The Battle? Undoubtedly. Do we ever feel as though the Go 5 is failing to communicate the inherent drama of the piece? No. In all honesty, we don’t.

The good news keeps coming, as the Go 5 steps in line with its latest-gen JBL counterparts by supporting 24-bit/96kHz lossless playback via USB-C. Hold down the speaker’s ‘play’ button as you plug in a USB-C cable and a happy sound will inform you that you’re now in wired playback mode.

We test lossless playback with Tidal playing on a connected iPhone 15, and find that our music sounds a touch clearer, crisper and more detailed when going wired compared with Bluetooth.

Just be aware that JBL doesn't tend to supply an in-box USB-C charging cable any more (as is increasingly standard for most brands, in a bid to minimise electronic waste), but we imagine most users will have a spare one knocking around these days, so that shouldn’t be too much of an issue.

Verdict

Laurel resting doesn’t seem to be JBL’s thing at the moment, especially when it comes to its strong line of portable Bluetooth speakers.

The Go 5 is the best Go yet, thanks to its handsome feature-set, stylish portable design and, for a speaker of its size and price, excellent audio quality. If you’re still playing your music through your phone’s speakers, it may be time to consider upgrading to one of JBL’s pocket-sized dynamos, because the Go 5 really is the real deal.
