I've heard a lot of premium wireless headphones in the past few months. No, seriously, when I say a lot, I mean a lot.
The Sony WH-1000XM6, the Sennheiser Momentum 5 Wireless, the Apple AirPods Max 2, the Sony 1000X The Collexion, the Bose QuietComfort Ultra Headphones (2nd Gen), the Bowers & Wilkins Px8 S2; the list just goes on and on.
And yet, this Amazon Prime Day, I would pick one pair above all others. Those aforementioned headphones are all excellent, sometimes spectacular, in their own respective ways, but one pair stands head and shoulders above the rest: the Sennheiser HDB 630.
At £400 / $500 / AU$1000, they're not cheap, and discounts aren't exactly common, but if you see a drop this Prime Day, across any of the major retailers, I would urge you wholeheartedly to snap it up while you can.
In fact, even if they don't budge an inch, I'd still be urging you to get hold of the best wireless headphones Sennheiser has ever made.
It's going to be a crazy twist of fate if some of the best wireless headphones you can currently buy this Prime Day aren't currently available on Amazon. Well, it's their loss.
In truth, forget Prime Day and Amazon altogether. Forget discounts and price cuts, and even brand loyalty. Just remember one key fact: if you want the best premium noise-cancelling wireless headphones, you want the Sennheiser HDB 630. It's that simple.
Why? Well, mainly because these are sound-first headphones that have pushed the needle for how good Bluetooth over-ears can sound at this sort of price. The HDB 630 are exceptionally smooth and natural-sounding headphones, with a beautifully realised bass reproduction, a sweet, immersive mid-range and a crisp, sharply defined treble.
They're fun, dynamically adept and musically expressive, walking that tricky tightrope between analysis and entertainment with sure-footed precision.
Part of that quality comes from the Sennheiser's super-clever BTD 700 USB-C dongle that you simply plug into your device’s USB-C port to give it aptX Adaptive superpowers.
That means that any source device, including your iPhone, gains aptX Adaptive hi-res streaming up to 24bit/96kHz, even if it wouldn't natively support it. That is, quite simply, an absolute game-changer, and it works terrifically.
Plus, you get wired listening via 3.5mm and USB-C-ended cables, around 60 hours of battery life with ANC switched on, very solid noise cancelling, a luxuriously comfortable fit and very solid voice calls, all of which combine to make an exceptional all-around package.
We get that Prime Day should be all about Amazon and, of course, all about deals, but the HDB 630 are so exceptional that all sort of goes out of the window.
Discounts don't really matter (although they're great to see). Retailers don't matter. What matters is that, if you can, you pick up a pair of some of the best-sounding premium wireless headphones we've ever heard.
