Is Bose all washed up? Bose Soundlink Max Portable Speaker review

Bose is a premium audio brand with a reputation for understated design, unrivalled power and sublime sound quality. It’s also a marque that commands an eye-watering price tag for some of its best speakers at times. So, I really wanted to put the Bose Soundlink Max through its paces as a fully waterproof high end portable speaker.

Spotify Premium, with its higher bitrate, sounded truly exceptional. The Soundlink Max’s speakers are perfectly tuned for a wide and precise soundstage with more bass than the average mini hi-fi. Battery life is typically well over 15 hours, and even the harsh edges of compressed internet radio stations were pleasingly softened by the Bose.

My waterproof testing ranged from spraying it with a garden hose (and the good old British weather) to sitting it on top of cutlery in a full kitchen sink. As for dust, some DIY filling and sanding provided a considerable layer of it. It made its way to every grill hole, every one of the silicone-covered buttons, and even the charging and aux ports. I’m happy to say that both worked fine after a brief puff of air. Most importantly, it still sounds amazing, with more power and range than its looks give it credit for. Find out more about the sound in my review, below.

Bose Soundlink Max Portable Speaker review

When I heard that I’d be testing a Bose speaker I had high expectations. After all, the brand is synonymous with premium quality across the board. But, that doesn’t mean I was about to give it a free pass.

Connecting to my iPhone via Bluetooth was fast and rock-solid – even outside with my phone over 20ft away indoors. I kicked off with an electro-pop playlist and the thunderous bassline of I Can’t Lose You by Confidence Man. The Bose Soundlink Max delivered so much power that, for a split second, I thought my Marshall Stanmore III had powered up by mistake. Bose’s decision to ditch the older Bluetooth version, used on its Soundlink Flex, in favour of Bluetooth 5.3 gives much more bandwidth. Controls are simple, too - with a programmable shortcut button, Bluetooth, playback and volume buttons.

This is one of the best Bluetooth speakers for bass that I’ve heard. It will literally shake the floor if you leave it there and rarely sounds overcooked. The rest of the soundstage is wide and extremely well-balanced. None of the detail became muddied in Bad Seamstress Blues by Cinderella, even at high volumes – probably down to the two 2.5-inch Bose drivers and single 0.79-inch tweeter behind that wide font-facing grill. To my ears, there’s a lot more range here than you might find in much larger active speakers.

Knowing the price of this thing, I hesitantly set about testing the Bose Soundlink Max’s IPX7 rating against dust, water and shock. With a blast of Don’t Fear The Reaper by Blue Öyster Cult to accompany its (potentially) final moments, I sat it in a sinkload of washing up. After that, taking it down to the local park and even sitting it on the roof while I washed the car was worry-free. It’s a real trooper, even after a couple of minor drops.

Verdict: A robust and deservedly premium product that delivers a well-defined soundstage

What’s good?

For me, the words Bose and bass are almost interchangeable now. Underneath that waterproof exterior, the Soundlink Max is up to some top-class audio wizardry. Given how densely packed they are, its two midrange drivers (alongside the tweeter) are capable of decent stereo separation. It won’t replace a quality hi-fi system, but it’s likely to outperform many much larger and similarly-priced portable speakers.

The addition of two-way USB-C charging is a welcome perk, working as a power bank in a pinch. I find it looks a little underwhelming for the money, but there’s no doubt that it's built to travel. I suspect there’s a steel chassis inside as it’s reassuringly weighty, at a hefty 2.2kg. It may be one of the best waterproof speakers around, but I don’t recommend putting it into warm water in a kitchen sink. I thought it was probably up to it – and I’m glad to be proven right.

The integration with the Bose app is excellent, too. It gave me plenty of fine control over equalisation plus checking the remaining charge and setting the shortcut button to play from Spotify. As for the battery, the Bose Soundlink Max kept on playing. It lasted close to 20 hours at medium volumes and took around five hours to fully charge – not lightning fast but fine for me.

What’s okay about the Bose Soundlink Max?

The rope handle is a welcome change of texture from the wall of blue silicone that gives the Soundlink Max its IPX7 protection. I like its bungee-style pattern, too. But, I worry that it might get grubby over time. Thankfully, it is removable, making washing easier.

Although the auxiliary input and USB-C ports are waterproof without a cover, I do think that the annoyance of getting sand or dirt into them would have been worth a protective flap. As it is, Bose recommends that you thoroughly dry the charge port before plugging in or risk damage. That said, it does have moisture detection to let you know if any water has made its way inside - which it did. You can still turn it on, but you’ll need to dry it out to charge it. This is a testament to Bose’s high-end engineering – the convenience of not having to fiddle around with a weatherproof cover will suit most users very well.

I’m a bit perplexed by the addition of a 3.5mm aux input on speakers like this. In practice, anyone who wants to play their favourite tunes not using Bluetooth will probably have a better amplifier and speakers nearby. But, I’m glad it’s there nonetheless. As for battery life, I did notice that playtime would reduce by an average of 30 per cent with higher volumes, which is reasonable.

Any negatives about the Bose Soundlink Max?

Although this fits with the slightly minimalist Bose aesthetic we’re all used to, I do find its looks a little underwhelming. I get that, at its core, it’s a simple device that needs few controls and can withstand being taken out and about. But, in its blue finish, I feel that it stops looking like a speaker worth almost £400 – after all, a budget Bluetooth speaker this certainly is not. But, that’s my personal take – those tired of the whole black-and-grey look for their speakers will love it.

As yet, there’s no ability to link this with another for better stereo separation – but that may be added this year via a future firmware update. Unlike many others, the Soundlink Max doesn’t have an onboard microphone – so you won’t be using this to pick up your incoming calls. I think this is a small oversight, especially on a device of this size and price. However, I do commend Bose for sticking so firmly to its ‘sound quality before extra features’ ethos. In many ways, it’s the gold standard of the no-frills approach to portable speaker design. As such, I think the Bose Soundlink Max should be at the top of anyone’s list of the best outdoor Bluetooth speakers for its sheer power and musicality.

How the product was tested

I tested the Bose Soundlink Max every day for around two weeks. It was used as a kitchen speaker (including playing in the sink while partially submerged), on the driveway while washing the car, and outside in various locations and weather conditions. It was also covered in dust from a DIY project. It was connected to an iPhone for playback, and an iPod Nano was used to test the auxiliary jack input.
