It’s changing into a repeated chorus so far as Trusted Evaluations is worried with the true wi-fi market – there’s simply so many choices from which to decide on.

Each model is getting in on the motion, attempting to enchantment to a variety of shoppers. When Technics final launched a real wi-fi pair, the AZ70W, it was pre-pandemic. Occasions have modified and Technics has tweaked its strategy, specializing in name high quality and luxury at a time when on-line video calls have turn into a daily fixture.

And at £129, the EAH-AZ40 bounce ear-tip first right into a aggressive space of the wi-fi headphone market. With Beats, Sennheiser, Cleer, and Urbanista all vying for consideration, the Technics are totally different in that they don’t include noise cancellation. Nonetheless, the AZ40 put ahead a assured case that you just needn’t essentially have it at this worth.


  • Compact and light-weight design
  • Comfy to put on
  • Wonderful noise isolation

The EAH-AZ40 can be found in vary of subdued colors, from Technics’ conventional silver look, to black and Rose Gold. I fairly just like the silver of this overview pattern, however the Rose Gold is hanging too. These earphones land on the extra inexpensive aspect of the spectrum, however this doesn’t imply they’ve traded for something lower than a classy look. Plugged into the ears they appear good, and with their IPX4 score they may double up for exercise use.

At 5g per earphone, theEAH-AZ40 are super-light within the hand – and the form of the housing is, for my part, excellent. They slot simply into the ears, the safety of the match and seal they create blocks a powerful degree of ambient noise, which isn’t in a too dissimilar trend to Sennheisers’ CX True Wi-fi vary. Contemplating the variety of earphones on the AZ40’s worth level which have jumped on the ANC prepare, the Technics make the case that noise cancellation isn’t the must-have function individuals consider it to be.

4 ear-tips sizes could be discovered within the field, from additional small to giant, and as talked about the earphones are rated to IPX4, which protects them from water or sweat. Notice that the case doesn’t have an IP score – however it’s as dainty because the earphones, and its brushed aluminium look is, once more, somewhat trendy.


  • Stable Transparency mode
  • Respectable battery life
  • Properly-featured app

In contrast to the Sennheiser CX Plus or Beats Studio Buds, theEAH-AZ40 don’t provide energetic noise cancellation to scale back the impression of ambient sounds. And, arguably, they don’t want it, their noise-isolating design is nice sufficient to blot out most sounds with ease.

You do get a Pure Ambient mode, nevertheless, and its efficiency right here is healthier than the one I sampled on the Panasonic RZ-S300W. These wi-fi earphones had been affected by an inconsistent and synthetic sound, however the Technics earphones are a lot clearer.

I ought to add that the Transparency mode right here isn’t probably the most detailed or incisive. Strolling in the direction of London Victoria, I used to be met with a broad sense of what was round me – however whether or not it was a small automobile, 4×4 or truck, all of them tended to sound the identical as they whooshed previous. You don’t get the identical degree of nuance the Studio Buds can provide, however it’s a nit-pick in what’s a stable go at providing extra consciousness.

Consideration mode focuses on voices and is finest used for listening to bulletins or partaking another person in a dialog. Its efficiency is nice, a transparent distinction between it and the Transparency mode because it locks onto individuals’s voices and tannoy bulletins.

Battery life is pretty lengthy at 7.5 hours per earbud and 25 hours in complete. Fast maths will inform you that 25 isn’t precisely divisible by 7.5, so that you get two-and a-bit prices from the case. Even so, utilizing them over the course of a number of days, the cost held up nicely; the variety of occasions I wanted to cost them has been comparatively few and much between. Plus, a fast cost of quarter-hour is nice sufficient for an additional 90 minutes of play.

I just like the Technics Audio Join app, particularly its sparse and clear look in comparison with the extra basic-looking Panasonic Audio app. There’s a component of sophistication about its look that matches the Technics model, and when it comes to operation it’s swift and frictionless.

Technics Control App settings

The codec wherein the headphones are taking part in is proven on the high proper, adopted by the identify (which you’ll edit), the battery life of every earbud, adopted by the Ambient Sound modes (click on by and you may select between the 2 modes). Unusually, the Ambient Sound part is replicated twice extra elsewhere within the app, which is a bit a lot.

That’s adopted by sound modes and the equalizer with its 4 modes (Bass, Vocal, Treble, Dynamic), and a customized possibility with a five-band EQ that may be adjusted from +10dB to -10dB frequencies. Or you possibly can have the sound with out enhancement. I’d recommend a mess around with what’s on provide.

Technics Control App customisations

Discover My Headphones is strictly what it appears like, with a couple of choices to find the earphones in case you’ve misplaced them. JustMyVoice has been added with on-line video calls in thoughts and works by isolating and amplifying what you’re saying whereas decreasing ambient sounds.

In my expertise, theEAH-AZ40’s name high quality is above common. The six particular person microphones suppress noise well-enough, the one points coming in very busy visitors areas. I used to be instructed by the individual on the opposite finish of the road that my voice got here by clearly and wasn’t preventing in opposition to the noise to be heard. On a aspect be aware, wi-fi connectivity has been robust, displaying no break-ups in areas similar to Waterloo and Victoria.

Shortcuts for Ambient and Sound settings could be discovered on the backside, alongside House and Settings. The latter affords extra customisation similar to contact controls, Bluetooth sign power (SBC or AAC) and the voice assistant you need to use (Alexa comes built-in anyway). As well as, there’s a upkeep part that provides tips about how finest to wash and keep the earphones.

Sound High quality

  • Not probably the most dynamic sound out of the field
  • Good element, spacious supply
  • Enjoyable sound that’s straightforward on the ears

The TechnicsEAH-AZ40 provide a genuinely satisfying sound, as a lot enjoyable as I’ve had listening to a pair of earbuds round this worth for some time. They’re not excellent, missing definition and a presentation that’s a bit tender, however they’re additionally very straightforward on the ears.

Low frequencies don’t have the explosiveness I’d like, and that’s a trait that (for me, no less than) is constant throughout Technics headphones. The underbelly is softer than some when it comes to punch, however in comparison with the Lypertek PurePlay Z5 ANC, for instance, there’s no less than extra vitality to their low-frequency efficiency.

It’s a spacious and large supply, too, clear sufficient to get an excellent sense of element; however the area round devices – these defining edges – isn’t fairly as clear-cut. Whereas I can hear the place numerous devices are positioned inside the soundfield, they don’t exist as components on their very own, extra like a soundstage that’s broadly outlined.

Nonetheless, the now Oscar-winning Dune soundtrack by Hans Zimmer is handled with an expansiveness the album warrants, with the bass in Dream of Arrakis displaying a heat to its expression that makes for a {smooth} hear. Excessive frequencies are high quality, if not fairly dropped at the fore with the headphone’s default EQ. Swap the EQ mode and there’s extra sharpness and refinement to be discovered.

Dynamism is first rate, however theTechnicsEAH-AZ40 don’t chew into these ups and downs with as a lot zeal because the Beats Studio Buds. It’s solely when taking part in round with the EQ and selecting the Dynamic mode do I get a extra pronounced sense of the peaks and troughs in a monitor. In truth, my most well-liked mode of listening with the EAH-AZ40 is with the Dynamic EQ on. This doesn’t simply provide some extra presence throughout the frequency vary (Ali Shaheed Muhammad and Adrian Younge’s Sumaré features extra thrust and punchiness), there’s a greater sense of movement and rhythmic capacity.

Technics EAH-AZ40 earbuds side by side

The Technics convey voices of Zara McFarlane in The whole lot is Related, for instance, or Chris Cornell in Soundgarden’s Black Gap Solar, easily sufficient – though there’s a crispness to Cornell’s vocals that does tread on the toes of sibilance when he enunciates “solar” and “wash”.

In any case, it’s a high quality rendition and listening to I’m Drained by Labrinth from the Euphoria soundtrack with the Vocal EQ on provides a delicate enhancement by nudging vocals into larger focus with out overemphasising or distorting vocals. I an enormous fan of those Technics earphones; they’re not probably the most fidelious, however they’re very satisfying.
