The Hed Unity headphones — the primary product from Swiss audio firm Hed — are groundbreaking. They’re the primary Bluetooth wi-fi headphones to additionally supply a Wi-Fi connection, which brings two main benefits: completely lossless transmission of audio — even at very excessive resolutions — and primarily limitless wi-fi vary.

Additionally they have a groundbreaking worth of $2,199 — making them the costliest wi-fi headphones we’ve ever reviewed. For that degree of funding, the Hed Unity are going to should examine loads of packing containers past lossless Wi-Fi.

After spending three weeks with them, I’m impressed with what Hed has achieved. However until you’ve got a compulsive have to be on the bleeding edge (and the discretionary money to help that compulsion) you might need to wait earlier than leaping into the world of Wi-Fi headphones.

Hed Unity: why Wi-Fi?

Earlier than we dive in, only a fast 101 on wi-fi audio: Bluetooth is the usual wi-fi expertise that connects headphones, earbuds, and audio system to your cellphone or different appropriate gadget. Its bandwidth (the quantity of information it may transmit per second) is restricted and grows smaller the farther away you might be out of your cellphone. Though there are some particular Bluetooth codecs on the market like LDAC, aptX HD, aptX Adaptive, and others that promise to protect the element present in your music, the fact is that none is ideal, and none is common — particularly if in case you have an iPhone, which doesn’t work with any of them.

Alternatively, Wi-Fi additionally has bandwidth limitations, however they’re nothing in comparison with Bluetooth. Wi-Fi doesn’t want particular codecs to assist protect info, and so long as you’re inside vary of a Wi-Fi entry level, your connection high quality must be superb. These qualities make Wi-Fi good for streaming lossless, hi-res audio. It’s the expertise utilized by the entire finest whole-home wi-fi audio system like Sonos, Bose, Bang & Olufsen, Sony, and lots of others.

However Wi-Fi is power-hungry, which has made it a poor selection for small, private audio merchandise like wi-fi headphones and earbuds. Wi-Fi audio merchandise require additional software program, and, a lot of the time, they can not hook up with a cellphone straight — they want a wi-fi community to behave because the go-between.

Hed Unity: design

Everybody has their very own thought of what luxurious ought to appear to be. For me, it’s all the time appeared like understated simplicity. Prime-notch supplies and construct high quality. Clear strains — no fancy, frilly particulars. Assume Porsche 911, not Ferrari Testarossa. By that customary, the Hed Unity are the epitome of luxurious — darkish gray anodized aluminum earcup shells that mix nearly seamlessly into an identical headband. The detachable reminiscence foam and microfiber-wrapped earcushions appear to be pure extensions of the carbon-reinforced nylon physique.

Apart from the small and tasteful unity emblem and the 4 management buttons on the earcups, nothing interrupts the movement. I feel they appear implausible, and I’m positive it’s no accident that Hed selected an aluminum colour that enhances Apple’s House Grey MacBooks.

In some methods, the Hed Unity is extra aligned with Apple’s design language than Apple’s personal AirPods Max headphones.

If there’s one disadvantage to the Unity’s minimalism, it’s a complete lack of hinges or pivots, which you’d discover on nearly every other set of wi-fi cans. Aside from the adjustable headband sliders, they don’t change form in any respect. This may need implications for consolation and match — which I’ll contact on in a second — however the greatest tradeoff is portability.

Hed ships the Unity with a journey and storage case constituted of a really light-weight but hard-shell materials that gives — in Hed’s phrases — “military-grade safety.” However the Unity’s inflexible design and the case’s building create a bundle that’s greater than twice as thick because the Bose QuietComfort Extremely Headphones — you’ll want loads of house in your carry-on for these cans.

Included with the case is a small round zippered pouch containing a braided USB-A-to-USB-C charging cable, a USB-C-to-USB-A adapter, and a USB-C-to-3.5mm analog enter dongle.

Hed Unity: consolation

At only a snick below 1 pound (14.4 ounces), the Hed Unity are even heavier than the hulking AirPods Max (13.8 ounces), which is saying one thing, particularly when the Sony WH-1000XM5 are simply 8.8 ounces. And but, regardless of their weight and lack of changes, I discovered them extremely snug. That sensation solely elevated as I switched backwards and forwards with a few of the finest wi-fi headphones in the marketplace.

The earcups are roomy and the reminiscence foam earcushions felt like they have been giving my head a smooth but agency hug. Even with some vigorous head actions, they stayed put, however I strongly advocate in opposition to taking them to the fitness center or on runs (they haven’t any sweat or water safety).

These Wi-Fi headphones include some weight to them.

The mass distribution, the scarf width, and the clamping power are all exceptionally well-balanced. There’s no denying you’ll really feel that almost 1-pound weight over time. However even after two hours of uninterrupted put on, I didn’t discover any strain factors.

My solely caveat is for these of you with actually small heads. At their smallest setting, they have been good for me, which means that (regardless of my tiny skull) a few of you might discover them too huge.

Hed Unity: controls and arrange

The Unity’s controls are pretty customary for wi-fi headphones. The appropriate earcup has a triple-button cluster that handles quantity, playback, and calling features, together with a fourth button devoted to lively noise cancellation (ANC) mode. On the left earcup is a single button that handles energy/Bluetooth/Wi-Fi and pairing actions.

Try to be conscious of two notable omissions: there’s at present no option to set off your cellphone’s voice assistant, and no auto-pause/resume characteristic for while you take away the cans.

The controls are intuitive, however the triple-button cluster is hard to make use of. The buttons are fairly small and really shut collectively, and the central multifunction button is barely taller than the flanking quantity buttons, which makes it arduous to find along with your thumb. I obtained used to it, however I by no means obtained snug with it.

The Hed Unity take a whopping 44 seconds besides up with Wi-Fi.

One other factor you’ll have to get used to is the time it takes to energy on the Unity. Most Bluetooth headphones take lower than 5 seconds to energy up and hook up with the final gadget you used. The Unity, nevertheless, take 44 seconds from the time you long-press the ability button till the time you hear the “Unity is prepared” message in your ears. It’s commonplace for Wi-Fi merchandise to take longer besides up than Bluetooth units — however that is lengthy, even for Wi-Fi.

Technically, the headphones reconnect over Bluetooth quicker than that. However for Wi-Fi operation, you want the complete boot-up time.

If you wish to strictly use the Unity as a set of Bluetooth headphones, you are able to do that proper out of the field. Simply energy them on, and so they’ll enter Bluetooth pairing mode. However that will defeat their fundamental promoting level. To get them working with Wi-Fi, you’ll want the Unity app (iOS/Android) and a few endurance.

The app makes the setup course of appear easy sufficient, however I needed to undergo a number of rounds of including and eradicating the headphones from my iPhone’s Bluetooth menu earlier than lastly getting them to be acknowledged by the app. As soon as that occurred, I used to be in a position so as to add the Unity to my Wi-Fi community and configure the choices. Not that you just get many.

The Unity app at present has 4 fundamental features: a battery meter, a Wi-Fi configuration instrument, a option to swap ANC modes, and an equalizer with a wide range of presets.

Initially, the Unity app was going to be a one-stop store for all of your music streaming wants, much like the Sonos or BluOS apps. For those who try Hed’s web site it nonetheless refers to a “multisource music participant” inside the app. However issues haven’t fairly labored out as deliberate.

As a substitute, to stream music over Wi-Fi to the Unity headphones, you’ll want to make use of totally different third-party apps relying on the place you get your tunes. Spotify and Tidal customers may have it straightforward — the Unity headphones are appropriate with the “Join” characteristic in these apps. Merely choose the Unity headphones from the record of obtainable wi-fi audio system inside the app and also you’re good to go.

You may not be capable to use your favourite music service.

Need to use different companies? That is perhaps an issue. There’s at present no option to stream Apple Music, even if in case you have an iPhone. The Unity help Wi-Fi, however not Apple’s AirPlay 2 streaming expertise. It received’t work on Android both as a result of Apple Music solely streams to Wi-Fi units which have Chromecast built-in — which the Unity additionally lack. The identical factor might be stated for Amazon Music, YouTube Music, Pandora, and Deezer.

For those who seize a third-party app like mConnect (iOS/Android) or BubbleUPnP (Android solely) you possibly can entry Qobuz — you’ll get three months of that free, by the way in which — plus your private library of digital music so long as it’s saved on a DLNA-compatible media server or gadget.

Hed didn’t supply a particular timeline for improved entry to music companies, nevertheless it has stated that it plans to embed streaming music functionality straight into its app by April 2024. For now, it’s honest to say that the corporate’s promise of “Your style is advanced and numerous. Now, it may be served by one centralized platform” is extra aspirational than achievable.

Hed Unity: wandering round with Wi-Fi

The Hed Unity’s Bluetooth wi-fi vary is about common for a set of wi-fi headphones. Whereas wandering between flooring of my home, it was typically secure. However the additional I roamed from my cellphone, the extra the audio would begin to break up.

Wi-Fi, nevertheless, by no means faltered. I’ve actually good Wi-Fi protection at residence, and it confirmed. Issues have been nice so long as I used to be inside vary of an entry level.

However they weren’t good. I’ve a Netgear Orbi mesh Wi-Fi system with two entry factors. As I drifted from the sting of 1 AP into the opposite, the Unity handled it like I used to be becoming a member of a brand new Wi-Fi community — every time asserting “Wi-Fi linked.”

I additionally seen that as a result of the headphones keep Bluetooth and Wi-Fi connections concurrently, I’d get a “Bluetooth disconnected/linked” message as I moved out and in of the Bluetooth vary of my cellphone.

You may, I suppose, merely power the Unity to disconnect out of your cellphone’s Bluetooth. However for those who try this, you lose the power to work with the Unity app. For now, given how little the app does, possibly that’s no hardship. It is perhaps a unique story sooner or later.

Hed Unity: sound high quality

Whether or not you’re utilizing them to stream lossless, hi-res audio by way of Wi-Fi, lossy audio by way of Bluetooth, or untouched sign by way of the wired dongle, the Hed Unity sound superb. No, not $2,199 superb — they don’t ship greater than 4 instances the audio high quality of a Sony WH-1000XM5, Apple AirPods Max, or Sennheiser Momentum 4 Wi-fi — however they do sound considerably higher to me than all three of those wonderful wi-fi headphones.

From a sound signature standpoint, they’re kissing cousins with excellent Grasp & Dynamic MW75 — very balanced throughout the frequencies, with simply the slightest trace of bass-forwardness. The Unity app comprises a beneficiant nine-band equalizer with saveable settings, plus a complete host of presets. I’m thrilled that these presets are labeled for what they do to the sound versus music genre-based labels, which have by no means made a lot sense to me. There’s loads of vary right here, however I feel you’ll discover the changes are delicate — simply good little tweaks that will help you get issues dialed in the way in which you want them.

A few of the credit score goes, I feel, to the 40mm titanium-coated drivers: transients are quick and exact, highs are fantastically clear, and the midranges abound with element. One in all my favourite tracks for torture-testing any audio gear is Billy Eilish’s Unhealthy Man. Having the ability to render the punishingly low bass line whereas concurrently letting Eilish’s whispery vocals float weightlessly on prime is not any straightforward feat, but the Unity dealt with it with ease.

Listening to Silver Springs by Matt Beringer — a monitor that makes wonderful use of instrument and vocal spatial positioning — reveals the Unity’s soundstage. It’s not massively large or excessive, nevertheless it’s tightly managed and really exact. This bodes nicely for when Hed updates the headphones with its promised spatial audio compatibility.

However right here’s the actual $2,199 query: does lossless Wi-Fi streaming make a noticeable distinction versus Bluetooth? Completely.

In comparison with the Unity’s Bluetooth connection, Wi-Fi streaming revealed extra element and nuance, let the music chill out, and eradicated probably the most annoying side-effects of compression — the bloating of bass and the sharpening of highs.

However is {that a} honest comparability? In spite of everything, in Bluetooth mode, the Unity solely help SBC and AAC — each lossy and restricted to 16-bit. Not precisely Bluetooth at its finest. In an ideal world, I might have examined aptX HD, aptX Adaptive, or LDAC on these cans, however alas, no cube.

Wi-Fi music sounds higher. Full cease. However 1000’s of {dollars} higher?

So I did the subsequent smartest thing and in contrast them to the Grasp & Dynamic MW75 linked to a Motorola ThinkPhone by way of aptX Adaptive. Utilizing Qobuz lossless tracks with each setups, I might detect solely the tiniest variations intimately. Provided that these headphones are shut — however not an identical — it’s unattainable to say if these variations have been as a result of wi-fi connection or any variety of different bodily and processing variations.

I’m compelled to conclude that whereas Wi-Fi is, on paper, one of the best ways to expertise wi-fi music, you don’t want $2,199 headphones to realize a high quality that’s 99% nearly as good (to my ears at the least). Nonetheless, this doesn’t detract from a key Unity profit: for Bluetooth to measure up, you want codec compatibility and also you want a really robust Bluetooth sign. Sony’s LDAC codec, as an illustration, is infamous for not having the ability to keep its highest bitrate of 990kbps until you’ve obtained almost good circumstances.

The Unity’s Wi-Fi connection enables you to overlook about all of that. Even the weakest Wi-Fi sign is prone to be many instances quicker than the most effective Bluetooth sign, and codec compatibility is irrelevant. For folk who like understanding they’re all the time getting the most effective audio potential, there’s actual worth in Wi-Fi — I’m simply undecided it’s $2,199’s price of worth.

Hed Unity: lively noise cancellation

I’d argue that the mix of the Unity’s passive noise isolation — because of these implausible earcushions — and their spectacular sound high quality is so efficient you in all probability received’t really feel the necessity to interact ANC more often than not.

Nonetheless, it’s a pleasant characteristic to have, and it does do a superb job of neutralizing many lower-to-mid frequencies for a quieter listening setting. It’s not as efficient because the ANC you’ll get from Sony, Bose, or Apple. And for those who’re not listening to any audio, you might discover a really small quantity of hiss.

My solely actual criticism is that Hed hasn’t added a transparency mode but (the corporate says it’s on the way in which), and there’s no option to disable the voice suggestions while you swap ANC on and off — maybe that can be up to date sooner or later, too.

Hed Unity: name high quality

Up till one week earlier than I obtained my analysis mannequin, the Hed Unity didn’t have voice calling over Bluetooth enabled. And primarily based on my expertise, Hed nonetheless has some work to do. The achieve on the mics is just too low, making your voice arduous to listen to, there’s nearly no background noise cancellation, and wind noise is an actual drawback. Issues have been higher indoors, with out background noise, however nowhere close to what we should always count on from a top-flight set of headphones.

In principle, these points must be fixable. In spite of everything, the Hed Unity is provided with an astonishing 12 microphones — 4 of that are devoted to calls. However for now, calling isn’t among the many Unity’s strengths.

Hed Unity: battery life

Let’s simply say it: the Hed Unity’s battery life is dismal. With a most playtime of simply eight hours — and that’s below optimum circumstances with ANC off and solely streaming over Bluetooth — you’d be hard-pressed to discover a set of wi-fi headphones with a shorter lifespan.

Why so quick? The Unity are filled with electronics. There’s a dual-core processor, a Wi-Fi transceiver, 16GB of storage, and a ton of movement sensors. This offers Hed loads of room to make the Unity higher over time, nevertheless it additionally takes a heavy toll on battery life.

On the intense aspect, it doesn’t take lengthy to cost them up: quarter-hour will get you about 90 minutes of additional playtime, and you may absolutely cost them in 1.5 hours.

Hed Unity: untapped potential

Contained in the Hed Unity are two applied sciences which can be at present unavailable to be used: 16GB of onboard storage for music and/or further apps, in addition to a nine-axis movement sensor that’s meant for a future head-tracked spatial audio characteristic.

Being first nearly all the time comes with a premium worth. The primary Tesla, the primary plasma TV, the primary folding cellphone — for those who wished to be the primary amongst your folks to personal these merchandise, you’ll have paid way over the oldsters who purchased them two years later. That’s the way it goes.

So, whereas the Hed Unity’s worth stays distressingly out of attain for many consumers, I have a tendency to consider them as a proof of idea. If those that can afford them purchase them and like them, it received’t be lengthy earlier than the market responds with extra inexpensive options. A few of these options would possibly come as quickly as 2024.

Within the meantime, the corporate’s first prospects are getting fabulous construct high quality, top-notch supplies, luxurious consolation, and sound high quality that has few equals within the wi-fi headphone world.

And naturally, they’ll get the marquee characteristic: Wi-fi connectivity that guarantees bit-perfect transmission of lossless music wherever in your house. Perhaps that’s well worth the worth of admission.
