Verdict

Axel Grell is no rookie. Notwithstanding, the first production to deport his name is greatly impressive in many respects. More please.

  • Impressive spec, with battery life a highlight
  • Built and finished to a high standard

Cons

  • App could be more comprehensive
  • ANC is ‘good’ rather than ‘slap-up’
  • Level of competition is feral

The Grell Audio TWS/1 are on auction now, and in the Britain are priced at £179. In the Us they sell for $199, while in Australia they cost about AU$299.

This puts the Grell in straight competition with a stack of decent alternatives from very credible brands. In fact, this sort of money volition buy yous truthful wireless winners from Bose, Sennheiser, Sony… and – if you absolutely must – this is Apple tree AirPods Pro territory, too. Information technology’s hard to see how Grell could have made things any harder for itself, really.

    Modulates the earbuds’ ability to block out sounds across the frequency spectrum

  • SoundID

Introduction

Axel Grell is 1 of ‘those’ names when it comes to engineering such as this. Those who know of him are aware of his long and illustrious career as a prime number mover and shaker in the world of headphones (particularly during his lengthy stint at Sennheiser), and venerate him accordingly.

Some of us might vaguely accept heard of him when the biggest headphone hitters are mentioned, and some of u.s. are reading his proper noun for the first time right here.

Which means the launch of the first production by his eponymous brand (stylised ‘grell’, as if he were e eastward cummings or something) will be met with nifty excitement by the starting time grouping, mild excitement past the 2d and, I’d imagine, relative indifference by the tertiary – who might imagine the TWS/1 are ‘merely some other’ pair of truthful wireless in-ear headphones.

And to be fair, the world is far from curt of true wireless headphones at this sort of money – it’s just that most of them are by brands with a little more contour than this. So practise the Grell Audio TWS/one have what it takes to bring the visitor to greater attention?

Pattern

  • Aluminium charging case
  • A variation on the ‘dangly stalk’ design
  • Piece of cake to position comfortably

You only go one chance to make a first impression, so they say, and it’s safe to say the Grell Audio TWS/1 grab information technology. The ‘Space Grey’ aluminium charging case looks and feels skillful, and when you flip up the sturdily hinged hat, the earbuds themselves look pretty decent, as well.

Infinite Gray as far as the buds are concerned means ‘mostly black with some space grey accents’, and the overall package looks and feels nicely premium. The correct earbud fits into the left-manus half of the charging instance and vice-versa, which is mildly weird, simply otherwise we’re off to a very good get-go.

The TWS/i are from the ‘dangly stem’ schoolhouse of true wireless earbud design, but the ‘earbud’ is basically circular when viewed from direct ahead, while the ‘stem’ is much shorter than most. Which makes the TWS/1 look like lilliputian audio frying-pans.

Each earbud weighs 7.3g – which means they’re far from the lightest earbuds around. However, the carefully ergonomic shape of the buds, forth with the wide selection of silicone and foam eartips that Grell Audio provides in the eco-friendly, unbleached paper-thin packaging, means they’re not remotely troublesome to fit and wear comfortably.

Features

  • Bluetooth 5.2 with AAC, LHDC and aptX Adaptive support
  • 10mm dynamic drivers
  • 34 – 45 hours of bombardment life

If you lot had any doubts over Grell Audio’ seriousness, a quick wait at the TWS/ane feature-count will dispel them. These are thoroughly and thoughtfully specified true wireless earbuds.

Wireless connectivity is via Bluetooth 5.2, with codec back up for SBC, AAC, aptX Adaptive and LHDC. The TWS/i use custom-designed 10mm dynamic drivers to evangelize sound, and they tin can do then for a full of 34 hours with active-noise cancellation switched on, or nearly-45 hours with it switched off. The buds hold betwixt 6 and eight hours of power (depending on ANC), while at that place are a minimum of four full charges in the example.

Grell TWS1 charging case

The instance tin can exist charged either via its USB-C socket or whatever Qi-certified wireless charging pad. Grell Sound is claiming reliable wireless connection over a altitude of 50 metres, and the earbuds are IPX4-rated confronting moisture.

Too as active noise-cancellation circuitry, the TWS/1 as well feature a arrangement rather charmingly chosen ‘Dissonance Annoyance Reduction’. NAR functions on the assumption that ANC acts most effectively on lower-frequency sound, which tin have the outcome of accentuating mid- and loftier-frequency sound. NAR scans the frequency spectrum and adapts the ANC to keep noise ‘annoyance’ to a minimum.

Control is available either via vox assistant (the TWS/1 are compatible with Bixby and Cortana, as well every bit the considerably more obvious Alexa, Google Assistant and Siri), or using the capacitive bear upon-surface on each earbud. This mode, play/interruption, volume up/downwards, respond/end/reject call, ANC on/off, NAR on/off, skip forwards/backwards and Transparency on/off are all available. It’s thorough, but in truth it isn’t the most responsive or reliable bear on-control organization I’ve ever encountered.

Grell TWS1 SoundID app

The TWS/1 are compatible with the 3rd-party SoundID app, likewise. It offers quite a degree of EQ aligning, including the opportunity to create a bespoke EQ using a hearing exam. Information technology’s too where you lot’ll be notified of firmware updates and the like. There’s no facility to accommodate the level of noise-cancelling, though – your pick is a binary ‘on’ or ‘off’.

Really, about the only characteristic the Grell Sound could conceivably do good from that they don’t already have is accelerometers – the TWS/1 will blithely continue playing if y’all take them out of your ears. But in every other respect, they’re specified to compete.

Sound Quality

  • Expansive, focused and information-rich sound
  • Plenty of free energy and dynamic headroom
  • Audio consistent with ANC on or off

In an ideal earth, true wireless earbuds audio the same no affair if their active noise-cancelling is switched ‘on’ or ‘off’. And that active noise-cancelling will act effectively and decisively on all external sounds. But this, as is surely obvious to even the almost casual observer, is not an ideal world.

And so while the TWS/ane manage to sound consistent regardless of whether noise-cancelling is engaged or not, the noise-cancelling itself isn’t the last word in, um, noise-cancellation. Oh, the Grell can reduce ambience audio a fair bit – but when compared to the acknowledged leaders in this expanse (Bose and Sony, predominantly), they’re plant slightly wanting. ‘Noise Badgerer Reduction’ is a laudable ambition, but in practice the best it can manage is to modulate ‘annoyance’ to something a bit milder, such every bit ‘vexation’.

As far as sound goes, though, the TWS/1 deserve less criticism. A Tidal stream of Buzzcocks’ Noise Annoys
(run across what I did there?) is delivered in fine and vigorous mode, on a big and well-defined soundstage. Tonally it’s even and convincing, from the impressive depth of the lowest frequencies to the crisply substantial superlative stop – and the mid-range is lavishly informative, and packed with detail and graphic symbol.

The Grell offer real insight into the recording, with each instrumental strand given due prominence and made uncomplicated to follow, even equally the earbuds integrate the dissever elements into a convincing whole. In that location’s plenty of free energy and blitheness to the performance, too as dynamic expressiveness and command.

Grell TWS1 charging case from a different angle

Switching to an MQA-powered ‘Masters’ file of The Good, The Bad & The Queen’southward History Song allows the TWS/1 to demonstrate their ability to generate and control super-deep bass frequencies without sacrificing any rhythmic certainty or bones momentum. The ample weight and punch of the recording doesn’t impact on the action happening in a higher place it, just it underpins the tune like the foundations of a tower block.

It doesn’t really matter what you want to listen to, the TWS/1 will requite yous the full and uncoloured motion-picture show. They’re as muscular or every bit tender every bit the music requires, and always insightful and engaging. Which means that unless your priority is to bargain with external sounds, they’re fully deserving of your consideration.

FAQs

What is NAR?

The TWS/1 blocks out noise in the high mid and high frequency range though its passive design. For dealing with low frequency range at that place is ANC but using dissonance cancellation can upshot in making higher frequencies more audible. The Noise Annoyance Reduction engineering science scans the racket spectrum and controls the ANC to reduce this consequence.
