SONY WF-1000XM4 Earbuds Deals

How does one improve on arguably the best all-around true wireless earbuds Sony WF-1000XM4 on the market? Sony has gone back to the drafting board and designed a fresh pair that look nothing like their predecessors – and therefore the results, the Sony WF-1000XM4. Is it a brave move? Definitely. Crazy? Quite possibly.

Sony’s WF-1000X range of wireless earbuds has been a dominant force during this category over the previous couple of years, and therefore the last pair to emerge from its stable, the WF-1000XM3, are two-time What Hi-Fi? Award-winners.

But rather than making the odd refinement here and there, Sony’s engineers have gone to town on the WF-1000XM4 with an all-new design, a replacement charging case, and a replacement audio processor. They need even found time to develop a replacement ear tip material, which here is appearing on a pair of Sony earbuds for the primary time. What could possibly go wrong?

Luckily for Sony, little or no does. In fact, the WF-1000XM4 is one of the foremost feature-packed, user-friendly, and sonically gifted pairs of wireless earbuds we’ve tested.

Sony WF-1000XM4: Design

 Your initial contact with the WF-1000XM4 may be a surprising one. Sony has ditched the standard glossy box for recycled packaging made up of a special blend of paper. This makes for a more compact box (34 percent smaller than the WF-1000XM3’s), and one that’s plastic-free. That’s excellent information for the environment, even though it doesn’t truly supply off the vibe that you’ve simply sold a couple of top-class noise-canceling headphones.

Once you’ve liberated the WF-1000XM4 from their packaging, you’re greeted with the aid of using a little, black charging case. It’s smaller than the case that incorporates the Bose Quiet Comfort Earbuds and undoubtedly tiny (forty percent smaller) in comparison with the charging case that incorporates their predecessors.

Sony WF-1000XM4: Specs

Bluetooth version: 5.2
Noise-canceling: Yes
Battery life: 8 hours (BT + ANC), 24 hours (total)
Voice control: Google Assistant, Amazon Alexa Finishes x2
Weight: 7.3g (x2)

The case charges via USB-C and also introduces wireless charging to the WF-1000X range for the primary time – all you would like is a compatible Qi charging pad. you’ll even battery share with compatible smartphones and piggyback off their power supply, too.

You shouldn’t need to worry an excessive amount about the battery life. Sony’s new buds might accompany a smaller case, but the XM4’s battery life is really up compared with the XM3. You now get eight hours of play from the earbuds with noise-canceling and Bluetooth turned on, and Sony claims the case can supply an extra 16 hours of charge. That places their battery life from one charge in particular major rivals.

Compare with others

The AirPods Pro can only manage five hours, the Sennheiser Momentum True Wireless seven hours, and therefore the Bose QuietComfort Earbuds six hours. close up noise-canceling and therefore the Sony’s life is extended to 12 hours from one charge and 24 hours with the case. A five-minute quick charge is sweet for one hour of playtime, too.

You can see the life remaining in both the buds and therefore the case through Sony’s Headphones Connect app. Which can also offer you a reminder when the case drops below 30 percent charge.

As with all wireless earbuds, battery life can vary thanks to a variety of various factors. As the standard of files, you’re taking note of, how hard the interior processor is functioning. And therefore the volume you’re taking note of. During our testing, we found the battery life consistently ok to urge us through each day of mixed-use.

Sony WF-1000XM4: Features

The circular outer surface of each earbud is a touchpad, and the Headphones Connect app lets you customize the functionality of each earbud. You can control volume and playback, or switch between noise cancellation and ambient noise with the usual combination of touches. , long tap and tap, and the headphones respond quickly to those actions. Switch between sound modes, change the volume, and enable and disable features like Quick Attention (which lowers the volume of listening so you can have a conversation quickly without taking your headphones out of your ears) with minimal effort. 

The Sony WF-1000XM4 borrows the speak-to-chat feature that debuted on the WH-1000XM4 wireless headphones. This feature allows you to speak to someone while the headset is still on and activates when you start speaking. It works well, although, like headphones. It only activates for about a second after you start speaking. This delay can be frustrating, as can the tendency for the feature to kick in with a cough or an impromptu karaoke session while you are at your desk.

You can decrease the sensitivity of the feature or turn it off completely and use quick attention, or remove a headset entirely (which will automatically pause playback). There’s a lot of new technology inside the XM4. The headphones have an improved DAC and an analog amplifier and are powered by a new onboard V1. Sony claims that it offers clearer sound and better noise cancellation than its predecessor. The new model also features Sony’s DSEE Extreme audio processor with Edge-AI. Which we have already experimented with on the WH-1000XM4 over-ear headphones. And which are designed to improve the quality of music files at low rates to high resolution. 

Improve sound quality and reduce noise, especially at certain low frequencies. AptX HD support is not on board, but the XM4 supports the LDAC file format from Sony. Which, transmitted via Bluetooth from a compatible source, enables the transmission of high-resolution audio files up to 24 bit / 96 kHz with data rates of up to 990 kbit / s enables. New features including beamforming and the use of a bone conduction sensor that prevents microphones from picking up the distracting environment while speaking. Sony aims to provide clearer call quality. There’s even an automatic wind noise reduction mode that tries to block the swirling noise. Which gets into your ears through the ear cup.

iOS users don’t get these pairing benefits. But all you have to do is open the case and take out the earbuds to start pairing. It is a shame that Sony has not implemented the activated “Multipoint” function on the WH-1000XM4 headphones. 

You connect the headphones to two different Bluetooth devices at the same time. This can be useful when you’re working on a laptop but still want to be connected to your phone. We hope it can be added at a later date. , we used an Apple iPhone 1 2 and a Macbook for most of our tests and found that the connection was rock solid without interruptions even in more urban areas.

Sony WF-1000XM4: Comfort

Open the magnetic case and you will see the new headphone design for the WF-1000XM4. Based on a combination of customer feedback on the XM3 and research on the human ear. Sony opted for a rounder case that sits farther inside. 

The matte finish of each earbud gives the earbuds a premium feel. While the small details around the microphone and sensor holes add a little pop of color. Speaking of color, the XM4s are available in black or silver.

 If you want your XM4 to work as a sport or running headset. You’ll be pleased to know that it has an IPX4 rating, making it resistant to “splashes from any angle,” a huge improvement over the previous model.

 In addition to the new headphones, the XM4 also has new olives. Made from polyurethane. Which feels like a mix of silicone and foam, Sony claims they help create a tighter, more stable fit. It is also said to help reduce and dissipate noise.

The only downside to this is that you only have one set of small, medium, and large tips to choose from. Sony says that with a pair you can get years of use, and of course more. Tips should be available when you need them.

We don’t have much of a problem pushing in and twisting the pads. If you’re struggling to seal, you can squeeze the tips together and slide them into your ear canal until they expand. We found that they sit comfortably in the ear opening but are comfortable during long listening sessions.


To make sure you have the perfect fit, Sony has introduced a new leak test that you can access through the Headphones Connect app. The application will emit a test tone and let you know whether or not you need to make adjustments. Especially if you feel like the sound lacks bass or there is some external noise.

In fact, we recommend that you install the Headphones Connect app the first time you connect the XM4. It gives you direct access to all important functions and functions of the headphones, so you can choose which ones to activate and deactivate. It also helps you listen to Sony 360 Reality Audio format music from compatible streaming services like Tidal and Deezer.

Sony WF-1000XM4: Audio Performance 

Carrying the WF-1000XM4 comfortably takes a little longer than it should. We found the insertion a little fiddly and found they should fit deeper in the ear than the case. But when that’s done you can configure the touch controls. EQ levels and countless other options to suit your needs. Is everything ready? Well. Time to put on some music. 

We started our testing with a Burner Tidal Masters file from Ross From Friends and the WF-1000XM4 impressed immediately. They do not give any undue significance to any part of the frequency range. They do not leave any detail unnoticed, and they do not let any rhythms or tempos hang. Its presentation is energetic and enthusiastic, but it is tempered by undeniable control. 

Bass Sounds

At the lower end, the headphones deliver bass sounds with substance, texture, and an absolute wealth of detail. There is momentum and momentum to be saved here. But the WF-1000XM4s never lose the race alone – there is the same balance that comes with it. The input and output of bass notes are clean and well defined. Which prevents the lower end from smearing in the mid-range.

Sony WF-1000XM4

The midrange itself is equally rich in information – listening to Kate Bush’s Lake Tahoe. The WF-1000XM4’s ability to pick up the smallest details or the most fleeting transients and incorporate them into a much larger picture was evident. Word when it comes to a person’s singing voice. But it’s absolutely appropriate here: if they’re anything, the WF-1000XM4 are communicative. 

The crossover from the mids to the highs is smooth and naturalistic. And the high notes themselves have a lot of sheens and bite without it. Both Kate Bush and Ross From Friends like to pack high-frequency information. But the WF-1000XM4 la controls just as neatly as the rest of the frequency range.

EQ Setting

 An unchanged EQ setting is assumed, which we should pay attention to. Sony is a bit unusual in allowing the end-user to play endlessly with the sound of their headphones. But the most natural and compelling sound comes from the WF-1000XM4 when its EQ is flat.

There is also little to complain about dynamically. The WF-1000XM4s are able to switch from “deafening” to “almost silent” and vice versa in no time, and even the most subtle harmonic dynamics of Bush’s piano playing are brought to full advantage. When it comes to rhythmic confidence and expression. Their combination of control and attack ensures they, like James Brown, are always on the right foot. All of this is endlessly supported by a compelling and natural timing and drive of the presentation. 

Active noise cancellation is a hit of the more qualified kind. The problem with all other ANC true wireless headphones is that the Bose QuietComfort headphones have shown that. It is possible to completely suppress external noise without leaving counter signals. And without affecting the quality of the music you are listening to. 

Sony WF-1000XM4

The WF-1000XM4 cannot do the same trick, but it definitely minimizes the impact of ambient noise on your listening experience. We are the market leader when it comes to noise cancellation. But for most people, we are extremely knowledgeable for the most part.

Battery Life

If you’re disquieted regarding battery, don’t be. The Sony WF-1000XM4 will last about seven hours and forty-three minutes per charge, and also the case can charge. The buds a minimum of 2 additional times for a complete of a hair underneath twenty-four hours. You’ll probably solely have to be compelled to charge. Your case on weekends though you’re an everyday commuter. Sure, it isn’t the most effective battery life. We’ve ever recorded for actually wireless earphones, however, there’s a great deal happening under the hood here.

How to dose Connect on your Phone

Unlike most headphones, the Sony WF-1000XM4 can be connected to your phone via Bluetooth 5.2, which might sound a bit boring. I assure you it is not. If you have a smartphone with a processor that supports this version of Bluetooth. You should see better battery life, and it’s also possible that these headphones could support. All of the mandatory codecs in the 5.2 stack, including LE audio. We asked Sony about this, but are currently waiting for an answer.

Like the Sony WH-1000XM4, the Sony WF-1000XM4 can use SBC, AAC, and LDAC codecs. If you want the high bit rate of LDAC, you need to enable the developer options in your settings window on Android. Scroll down to Bluetooth Audio LDAC Codec Selection – Playback Quality and select from the list. We believe your best results are at 660 kbps, but your results may vary.


We’re quite taken by the Sony WF-1000XM4. Given all the planning changes and new options in these wireless earbuds. It should be a true challenge to induce them right. However, Sony has completely nailed it. The headphones deliver a satisfying user experience, class-leading battery life. A number of the best noise-canceling we’ve detected during this category. Absolutely beautiful sound quality, Place simply, this is often a brand new benchmark for premium true wireless earbuds.
