It’s onerous to pen down an inventory of the most effective actually wi-fi earphones out there with out mentioning Sony’s wonderful WF-1000X vary. The corporate’s choices have, for essentially the most half, knocked the competitors right into a cocked hat and for good purpose – in any case, the model’s flagship vary doesn’t simply provide spectacular acoustics, however comes with class-leading adaptive ANC, amongst different issues. That’s partly why I used to be enthralled when the corporate despatched me their flagship WF-1000XM4 for assessment. Launched again in 2021, the earphones have solely simply made their manner over to the Indian shores.

Design and Consolation

I keep in mind auditioning Sony’s WF-1000XM3 again in 2020 on a visit to Taiwan. Proper off the bat, I used to be obsessed on the unit’s ANC chops, in addition to the pair’s immaculate sound high quality. That mentioned, the unit’s match left an amazing deal to be desired and I couldn’t come to phrases with utilizing the chunky earphones day in and time out. Properly, Sony clearly went again to the drafting board because the newer WF-1000XM4 touts a smaller footprint – 10 p.c smaller, to be exact.

Don’t get me improper – the earphones are nonetheless fairly cumbersome and have a tendency to weigh my ears down after I’m figuring out. That’s partly why I didn’t take advantage of the unit’s IPX4 ranking because the earpieces would fall off after I was doing handstands or burpees. Regardless, not like their predecessors, the pair appears to be like extra refined draped round a person’s ears. What’s extra, the corporate has additionally lowered the scale of the charging case by round 40 p.c. Consequently, not like the M3’s, the WF-1000XM4 comes bundled in a extra pocketable case too. 

Sony didn’t simply cut back the general measurement of the earpieces and the case, thoughts you. The form of the earpieces, for one, is sort of completely different too and the newer mannequin conforms to a rounder aesthetic. The corporate has utilised a matte end for the outer shell which when paired with the earphone’s shiny steel accents, imparts a fairly luxurious in-hand really feel. That’s not all, because the pair additionally ships with a brand-new set of noise isolation ear suggestions which have been particularly deployed to mitigate noise higher. A fringe good thing about the identical is that the ear suggestions conform to the form of the person’s ear canal akin to foam suggestions, thereby creating a cushty in-ear seal as nicely. Relaxation assured, you may sit and work with the M4’s in your ears for hours on finish with out feeling any discomfort or listening fatigue. 

As a lagniappe, the WF-1000XM4’s in any other case sizable earpieces provide a beneficiant contact floor, guaranteeing you may toggle numerous system instructions and management the music playback with out having to succeed in on your telephone. What’s extra, you may even customise the actions invoked by tapping on both the left or the correct earpiece. To take action, you’ll want to put in the corporate’s Headphone Join app in your Android or iPhone. As soon as carried out, you may head on over to the ‘system’ sub-head and tweak the inputs for both earpiece. The contact controls have been lots responsive throughout my testing and I by no means discovered myself tapping an earpiece again and again to register my command both, which is nice. 

App, ANC, and different options

As prefaced beforehand, the Sony WF-1000XM4 ships with a companion app dubbed Headphone Join which is offered for each, iOS and Android platforms. Now, the earphones work with out the app too, however the utility permits a slew of options that make utilizing the M4 extra enjoyable. Take the Converse-to-Chat characteristic, for example, which when enabled, routinely pauses the music playback and heightens a person’s sensitivity to ambient sound the second they begin talking. 

The characteristic is extraordinarily intuitive and could be triggered by a lot as a cough. On the flip aspect, in the event you are inclined to sing or hum while listening to music, you would possibly wish to preserve the utility disabled as it can abruptly pause your playback. Fortunately, it’s also possible to use the earphone’s Fast Consideration characteristic, which works similarly, albeit requires an extra step. To wit, customers can toggle the earphone’s Fast Consideration characteristic by long-pressing the left (or the correct) earbud. That’s not all, because the earphones additionally assist ear detection and can conveniently pause a music in the event you take away an earbud. 

Actually, these options are however the tip of the iceberg within the WF-1000XM4’s repository. Working example, the earphone’s adaptive sound management tech, which flips between 4 completely different exercise presets, as per your actions and environment. Notably, the earphones can gauge whether or not you’re sitting idle (staying), strolling, working, or commuting (transport). Every preset could be customised to both allow ANC, or a selected stage of ambient sound. The earphones additionally assist the corporate’s DSEE Excessive enhancement that upscales a comparatively decrease bitrate audio file to high-res high quality. Lest I overlook, the earphones are compliant with Google’s quick pairing protocol and also you’ll discover a immediate pop up in your Android telephone the second you open the lid of the WF-1000XM4’s case. Sadly, I couldn’t fairly get the pair to connect with two gadgets concurrently, which is a bummer. 

The Sony WF-1000XM4 doesn’t disappoint within the ANC division both and the pair can comfortably cancel out the humdrum of an engine, or the chitter-chatter in an workplace area. I, for one, routinely use the earphones each time I’m drafting a product assessment on my PC. You see, I occur to have a mechanical keyboard with significantly loud blue switches and the WF-1000XM4 dampens the noise from the important thing faucets significantly. Relaxation assured, patrons choosing the earphones won’t discover the pair missing within the ANC or software program division. 

Sound High quality and Battery life 

Coming to the crux of the matter, the Sony WF-1000XM4 is backed by a pair of 6mm drivers positioned inside every earpiece. The earphones assist SBC, AAC, and LDAC codecs and might function throughout a frequency vary of 20Hz to 40KHz. Do word that I used Apple Music’s lossless media for the aim of my testing. I had additionally set the earphones to function solely on the high-bitrate LDAC codec. 

Going into the assessment, I anticipated to be wowed by the M4’s audio prowess and positive sufficient, the pair lived as much as my expectations. Now, Sony has a repute for launching stable bass-driven earphones, and the corporate’s flagship TWS isn’t any exception to the rule. To wit, the earphone’s bass output provides numerous weight and punchiness. The beats impression with a satisfying slam and the sound output not often ever feels bloated or muddy. In truth, out of the field, I seen the M4’s laid better emphasis on a monitor’s low-end output. Nonetheless, dialling down the bass manually or by choosing the ‘Brilliant’ preset paves the way in which for a extra refined listening expertise. 

To my ears, the Sony WF-1000XM4 excelled in delivering meaty beats with phenomenal depth and texture. On the similar time, the earphone’s vigour in relaying thunderous bass was by no means a thorn within the aspect of the remainder of the frequency spectrum. Take DDJ’s Moon Strolling Via The Calabasas whereby, the rhythmic beats albeit impactful, don’t take the limelight away from the vocals, or the guitar strums. What’s extra, not like most bass-forward earphones, the M4’s low-end output doesn’t have an effect on the tonality of the devices or the vocals in play. Working example, Wasted Instances by the Weeknd, a monitor that’s chockablock with energetic beats. Be that as it might, I couldn’t assist however faucet my toes and sing alongside to the luxurious, detail-laden, and natural-sounding vocals introduced by the WF-1000XM4s. 

The surroundings remained unchanged after I converted to Motion by Hozier too. The thumping slam from the kick drums initially sounded surreal, although the bass line didn’t take something away from the monitor’s soothing vocals both. It additionally helps that the earphones don’t sound sibilant, so you may even use the pair to hearken to your favorite podcasts. I’d additionally like so as to add that the M4’s provide stellar imaging, so tracks layered with numerous devices and SFX don’t sound muddy or congested. Porter Robinson’s Goodbye To a World is an effective instance of the identical and through the build-up for the primary verse, the soundtrack introduces a handful of devices and sound results. Regardless of that, I might comprehend the intricacies of every instrument with utmost readability. On the flip aspect, the M4’s treble output leaves one thing to be desired. To that word, songs from the rock or steel style don’t sound very energetic. The strums from the electrical guitar in Mr. Brightside, for example, lacked chunk. 

Fortunately, the Sony WF-1000XM4 provides a large battery backup, guaranteeing you may hearken to your favorite songs for every week of Sundays. On common, the earphones lasted me round seven hours off a single cost, and that’s with ANC enabled. The bundled case can recharge the earphones round two-three instances too, which is nice. What’s extra, the docking case helps wi-fi charging as nicely, thereby permitting customers to cost the earphones seamlessly. 


The Sony WF-1000XM4’s pricing isn’t for the faint of coronary heart and the earphones retail for Rs 19,990 in India. With that mentioned, the pair does greater than sufficient to justify its steep value and provides a treasure trove of options, together with cutting-edge adaptive ANC,  a classy, all-day put on design, and surreal audio high quality. Now, do word that Sony isn’t the one vendor invested within the premium TWS earphones area and patrons on the lookout for a pair of top-notch, wire-free buds can be spoilt for selections. To wit, the WF-1000XM4 goes up towards the Samsung Galaxy Buds Professional (assessment) which retails for significantly much less and comes toting class-leading options too. Nonetheless, the M4’s put forth a well-rounded bundle that’s fairly onerous to beat. The Galaxy Buds Professional, for example, doesn’t assist any excessive bitrate audio codecs and consequently, can not relay as a lot data.

Then again, these invested in Apple’s ecosystem will discover lots to love concerning the AirPods Professional too. In truth, not like the M4’s, the AirPods Professional provides seamless connectivity with an iPhone. It additionally helps that the earphones deal with voice calls higher. That mentioned, Sony’s providing sounds a tad higher. All mentioned and carried out, the Sony WF-1000XM4 doesn’t have any inherent shortcomings and consequently, patrons on the lookout for the most effective of the most effective will really feel proper at residence with the earbuds.
