We’re tempted to call Sennheiser the ‘dark horse’ of wireless headphones.
After all, our best buys have, in more recent times, been stacked to the brim with offerings from the likes of Apple, Bose and, more than any other, Sony, so it has been easy to forget the many qualities that Sennheiser brings to this particular slice of the audio terrain.
Let’s not forget, however, that this is a brand that has been around since 1945, a brand that, when not making the occasional microphone or soundbar, has built its reputation at the sharp end of both wired and wireless headphone production.
Perhaps ‘sleeping giant’ would have been a more apt moniker.
Admittedly, Sennheiser hasn’t quite been as prolific as its esteemed rivals when it comes to the actual volume of products sent to market. And the company’s ongoing search for a buyer since Swiss owner Sonova put its headphone division up for sale has naturally made waters all the choppier. From what we have seen of Sennheiser recently, though, it is still more than capable of taking the fight to the very best in the business.
The sound of success
We wonder if the release of the five-star HDB 630 will end up becoming something of a defining moment for Sennheiser.
Released just a few months before the announcement that the company’s headphone division was going up for sale – with some doom-mongers rather rashly predicting the death of entire brand – the audiophile-tuned HDB 630 now look like a major signal of intent.
We’ve always known that this is a brand capable of excellence in the wired space, though it had been a while since Sennheiser had properly flexed its wireless muscles. The soon to be phased out mid-priced Accentum line, including the Accentum Wireless and Accentum Wireless Plus over-ears, had failed to set the world alight, and it had been almost four years since we’d heard a hint of any addition to the premium Momentum Wireless range.
Rival standards were high, too. The Sony WH-1000XM6 looked unassailable at their £400 / $450 / AU$699 price, while the likes of Bowers & Wilkins, Bose, Apple and Dali were all also vying for the crown. Competition was, is, and probably always will be, incredibly fierce.
Yet the HDB 630 really pulled it out of the bag. Sennheiser’s outstanding cans set a new standard of wireless sound at this level, thanks in part to their clever bundled Bluetooth dongle, with a sonic performance that blew most of their competitors out of the water. Including Sony.
As we say in our review: “Here, precision and analysis go hand in hand with drive and vigour, making for the most informative and entertaining sound we’ve heard from wireless headphones at this price, with or without the use of the dongle.”
The Momentum 5 Wireless have repeated a similar trick, and while they’re not as boundary-pushing as the HDB 630, their aggressive price tag (£330 / $400 / AU$749) and rich, smooth sound make them a very fine alternative to the Sonys and B&Ws of this world.
Two five-star pairs with a strong focus on stellar sound and plenty of features in tow. If that isn't a warning to rivals to sit up and take notice, we don't know what is.
Take a chance on me
God loves a trier, but He also favours those who take a few risks.
It feels as though Sennheiser has recognised a need to innovate in order to get ahead of a crowded pack, and while the temptation to go in for zippy gimmicks and check-box features must have pulled hard, resisting such inclinations has paid dividends.
As has putting efforts into genuinely constructive innovation. We gave significant attention to the bundled Bluetooth dongle when reviewing the Sennheiser HDB 630 last year, and not without reason: it turned out to be the premium over-ears’ small-but-mighty secret weapon.
Essentially, it’s a clever little USB accessory that gives your phone or other audio source the same high-quality Bluetooth codec the headphones themselves support, meaning you have improved codec-support from devices which might not normally (we’re looking at you, iPhone) have supported them.
That’s a big deal, and as we wrote at the time, the “dongle proves a valuable accessory. When connected to an iPhone 16 and old Samsung Galaxy S21, upgrading their respective AAC and aptX connectivity with the headphones to aptX Adaptive, the presentation gains in clarity and solidity.”
The Momentum 5 Wireless have kept up with the times, too. There’s no dongle to be found, but with extensive codec support, wired listening via USB-C and 3.5mm, Dolby Atmos all on board, Sennheiser’s flagships have kept up admirably with the likes of the Sony WH-1000XM6 and the Bowers & Wilkins Px7 S3. 57 hours of battery life with ANC on doesn’t exactly hurt, either.
The new Momentum 5 Wireless don’t necessarily have the most features of any premium pair, but in terms of quality, they’re up there with the best.
A case of re-taken identity
Perhaps ironically, and certainly impressively, Sennheiser seems to have re-found and re-established its identity at a time of not-inconsiderable uncertainty.
While the likes of the Accentum line and the disappointing Sennheiser Momentum Sport earbuds seemed to play it safe with a flat, tonally grey sound, the premium Momentum 5 Wireless and HDB 630 feel like Sennheiser returning to a place where it is the most confident and comfortable.
In fact, when we spoke recently to the German manufacturer about where it saw its future, there was a clear statement that the Momentum Wireless line would be a prospective listeners’ “entry point” into the world of Sennheiser sound.
From there, they could progress to the HDB 630 and beyond into even more premium and high-end wired options. But the message was clear: Sennheiser would be providing audiophile-type performance to proper enthusiasts.
It appears to be a sensible move. Sennheiser does great work when it targets this more audiophile-centric side of the landscape – just see the wired Sennheiser HD 820 for proof – and with so many brands already targeting mass production of cheaper, spec-heavy wireless earbuds and headphones, it make sense to stick to more rarefied territory.
And, from what we’ve heard, it’s what the company seems to rather good at.
Sennheiser’s resurgence feels like a good thing for the wireless headphones industry.
It’s good for customers to have a healthy number of options when picking out a potential product; it’s good for the market not to be strangled for a monopoly; and it’s good for rival companies to compete with one another for supremacy in order to push the needle of quality ever forward.
When working as it’s supposed to, that’s sort of the point of a free market, isn’t it?
Producing two or three excellent pairs of headphones doesn’t suddenly make you the king, especially with the likes of Sony putting out five-star headphones across the cost spectrum, over many successive years. What they do indicate, though, is that Sennheiser feels like a company finding its groove again, and, in the midst of a potentially turbulent time, re-establishing its identity amid a sea of change and challengers.
If a worthy successor to the Momentum True Wireless 4 earbuds also ends up landing later this year, we might end up looking back at 2026 as being the year of Sennheiser.
