The surprising way Ozlo Sleepbuds helped me sleep so much better

The surprising way Ozlo Sleepbuds helped me sleep so much better

CNN04-03-2025

Sleep is a deeply personal thing. Nearly anyone you ask will have a different pattern, rhythm, feeling or complaint. Unfortunately, I have never been a great snoozer. I'll be the first to admit: I'm fully jealous of anyone who can sleep through the night and wake up feeling refreshed. However, the Ozlo Sleepbuds are a sleep aid I just can't do without.
Ozlo may be a newcomer to the sleep headphones space, but the company has a distinguished pedigree. Taking up the mantle from the excellent yet discontinued Bose Sleepbuds 2, three former Bose employees resurrected this cult sleep favorite by acquiring the Sleepbuds trademark — and created a similarly comfortable product, which levels up with all-night battery life and biometric sensing.
At $300, these sleep headphones are not a bargain. However, since the demise of the Bose Sleepbuds — my previous favorite sleep headphones — I have not found a better, more comfortable or more efficient way to block out nighttime noise.
Ozlo Sleepbuds
The Ozlo Sleepbuds are a game changer when it comes to better sleep, offering unmatched comfort, a secure fit and superior noise masking. Designed for all-night wear, they block out disturbances like my husband's snoring and all types of ambient noise while allowing personal audio streaming that seamlessly transitions to sleep sounds. Secure and comfortable design
The first rule of sleep headphones? They have to be comfortable. I dare you to stick a pair of Apple AirPods or any earbuds crafted from hard plastic in your ears and try to sleep through the night. Ozlo Sleepbuds fit the bill because the ear tips are made of a smooth, squishy silicone, and you can choose from four different sizes — XS, S, M and L — for the perfect fit. After trying on a few, I ended up using the medium-size tips that they came with.
But what I like most about the Ozlo Sleepbuds is how simple they are to put on. Just stick the tip in your ear canal and use the silicone wing to hold them securely in place. There's no fussing or fumbling, an important feature for a product you'll use regularly, and because they're so soft and lightweight, the Sleepbuds feel completely natural, even when I'm sleeping on my side. Also, unlike our previous pick for best tested sleep headphones, the Soundcore by Anker Sleep A10 sleep headphones (once the Bose Sleepbuds bit the dust), I have not once woken up to a lost Ozlo Sleepbud.
So long, snoring
Most folks turn to sleep headphones to mask nighttime noise. For some, it's things like traffic or general city commotion. Others may be trying to tune out noisy roommates or a partner's late-night TV habit. For me, it's snoring. Specifically, my husband's snoring. The poor guy is dealing with a deviated septum, but it's still an utter cacophony once he's dozed off. Because they're so well crafted, the seal on these Ozlo Sleepbuds is outstanding, tuning out all unwanted noise once they're safely in your ears, which means I don't hear a darn thing.
Smart, personalized tech
The beauty of these Sleepbuds is that they can, and do, block that unwanted noise with no extra fanfare. But for $300, you better believe Ozlo added some ingenious tech for more customized rest.
As with most smart personal technology products, you'll need to download the corresponding app and set up your Sleepbuds using your phone, but it won't take long. When you're ready to connect, just slide open the sturdy, rounded charging case and the app will find and pair with the device.
You can choose from a library of 10 noise-masking sounds to play while you sleep, which range from Ocean Tide to Babbling Brook to Fireglow. But unlike the Bose sleep headphones, Ozlo made a distinct upgrade with its Sleepbuds, also allowing you to stream your own Bluetooth audio from any source (think: music, audiobooks, podcasts or even a custom white noise). And to seamlessly combine these two features, built-in sensors will detect when you fall asleep and automatically switch from personal audio to your chosen sleep sound.
I'm also a huge fan of the added personal alarm because, guess what? The Sleepbuds are so good at their job, I can't hear my alarm clock in the morning. You can choose your alert and set it to your preferences via the app. And trust me, you're not sleeping through this.
Battery life lasts all night and beyond
Ozlo chose a medical-grade battery from Varta for the Sleepbuds, which allows for about 10 hours of battery life. They also come in their own charging case, which Ozlo claims will add an additional 32 hours. And don't think I don't throw these in my bag when we travel because, unfortunately, snoring knows no time zones.
The price
Well, yes, there's that price tag. Most folks don't spend $300 lightly. You can nab our previous best tested winner, the Soundcore Sleep A10 sleep headphones, for just $110, though I found them to be significantly less comfortable. However, the Ozlo Sleepbuds are HSA/FSA eligible, which might help justify the cost.
Lack of sleep data
One of the biggest drawbacks of the Sleepbuds' current software is the lack of sleep data. For such a steep price, I expected this feature right out of the gate, especially with the advanced tech built into the headphones.
Ozlo acknowledges this and has promised an upgrade in Q2 of this year. 'Sleep and environmental tracking capabilities (light, temperature and noise) will give users insights into their sleep patterns and how their environment affects rest, including suggestions to address disruptions,' an Ozlo representative confirmed via email.
Look, I get it — $300 is a whole lot of cash to plunk down. But if you, like me, have serious trouble falling or staying asleep, it's a literal investment in your health and mental state. Sure, you can spend less and still block out some noise, but the Ozlo Sleepbuds are the only sleep headphones on the market that feel 100% natural, stay in my ears all night and offer a tight seal against the nightly clamor that is my husband's snoring (oh man, I'm gonna get it when he reads this). Plus, I appreciate the ability to stream my own audio in bed, along with the Sleepbuds' sleep detection and automatic shift to my chosen noise-masking sound.

Sony WH-1000XM6 vs. Bose QuietComfort Ultra: Can Sony Snatch the Noise-Canceling Crown?

Which are the best noise-canceling headphones you can buy in 2025? All products featured on WIRED are independently selected by our editors. However, we may receive compensation from retailers and/or from purchases of products through these links. Every couple of years, Bose and Sony trade blows in an effort to claim the title of the best noise-canceling headphones you can buy. Until recently, Bose's QuietComfort Ultra (9/10, WIRED Recommends) had the edge, offering world-crushing cancellation that bested Sony's still-great WH-1000XM5 (9/10, WIRED Recommends) and other top models from the likes of JBL, Sonos, and Apple. Now, Sony's back with its latest WH-1000 model, the predictably titled WH-1000XM6 (9/10, WIRED Recommends). The new pair offers an almost startling armament of microphones and noise-cancellation tech, along with improved sound, style, and features. So can it claim the title? Let's dive into the details. Look and Feel Starting with aesthetics, neither of these plastic-clad models stands out like Apple's iconic (and heavy) AirPods Max, but both manage to blaze their own trail to match premium pricing with a posh design. Sony's XM6 gets a refreshed plastic matte exterior that feels both grittier and more robust than its predecessor. Along with extra style points, the new design rectifies one of the XM5's biggest detractions with a new hinge point along the arms that once again makes Sony's best wireless headphones foldable for travel. This leads to a more travel-friendly case, including a design refresh that swaps the zipper top for a convenient magnetic flap. As for the all-important fit, the XM6 rely on thick padding and clamping force along the earcups to keep them secure, but the headband pad is surprisingly thin. The headphones are still comfortable for hours of wear, especially once you break them in, but the band tends to wear on my head more over time than the more lavishly appointed QC Ultra and other favorites like the JBL Tour Pro M3. Bose's pair applies more glitz than the understated XM6, highlighted by sleek curves, a more sumptuous protein leather coating along the pads, and speckled metallic armpieces that grip smaller earcups. Like the XM6, the Ultra fold easily for travel, and their smaller size translates to a slightly more compact case. Though you'll miss out on the zipperless lid, when it comes to a more premium look and fit, Bose's pair takes this category. WIRED: Bose QuietComfort Ultra Features and Controls Both pairs are loaded with flagship features, including conveniences like multipoint pairing, auto-pause sensors, and replaceable earpads. Each model includes a loaded app for tinkering and customizing features like adaptive noise canceling and transparency modes, among multiple other parameters, and both opt for analog audio input rather than USB-C playback from their charging ports. Bose has its specialties, including a more accessible and intuitive app layout. Sony's app is more complicated but also provides more ways to explore and adapt, like a multiband EQ that goes well beyond Bose's three-band version. You'll also get Sony stalwarts like the ability to hold the right earcup to temporarily activate exterior sounds. You might even say Sony goes a little overboard on the feature front, but as we've come to expect, the XM6 keep the most important stuff up front, embodied by the best control system on the market. Simply double tap the right earcup for play/pause, swipe up or down to raise or lower volume, and forward or backward for song skip. Dedicated power and ambient audio keys on the left earcup complete the layout for a remarkably intuitive and responsive experience. Bose's QC Ultra pack their own control innovations, including a handy new volume slider pad that's accurate enough to dial in your levels without blasting your ears. The other controls are less convenient due to their reliance on a two-button solution that puts a lot of weight on the multi-key. The main drawback is the need to hold the key down to laboriously cycle through ambient sound modes, compared to Sony's dedicated key that cycles with a quick tap. It's not a massive difference, but Sony's mix of simpler controls and deeper, more granular features gives its pair a leg up in usability. WIRED: Sony WH-1000XM6 Noise Canceling and Transparency Mode Before digging in here, it's important to note that both of these pairs offer noise canceling that bests everything we've ever tested. If you need to kill the noise, either pair will do so to an almost disorienting level. With a total of 12 microphones and an advanced new chipset, Sony claims its latest headphones have the best noise canceling on the market. When A/B testing without music, this was difficult to prove. Both are fantastic at removing low-end sounds like my go-to Airplane drone video, while effectively quelling high-register sounds like keystrokes, vacuums, and vocal chatter. What's immediately obvious is how much faster the XM6 works to kill sound, giving them an edge in some key areas. Sony claims its new QN3 processor is '7X faster' than the previous pair's QN1 chip, which translates to crazy-quick response to your environment. Where Bose's pair slowly squashes noises as it analyzes them over time, the XM6 react almost instantly to everything from passing cars to my electric leaf blower. As Wired editor Parker Hall pointed out, the XM6's faster response time also aids their noise canceling in the way most people listen, with music playing, by adjusting the output in real time with your tunes. In testing with light music playing, Sony's pair did seem to offer a slight advantage over the Ultra, especially with sharper annoyances like my ever-vigilant barking dog. Even so, both pairs are so powerful that a little music puts you in the void from virtually all sounds anyway. Transparency mode, the diametric opposite of noise canceling, is similarly close, but again, Sony's faster response time enhances performance. Both pairs sound quite natural, but Sony's model reacted more effectively in real time to punchy sounds like the slamming of my back door or a loud clap, while Bose's pair takes longer to adapt. Sony's blazingly fast silicon seems to be the real secret to the XM6's incredible ambient audio skills. WIRED: Sony WH-1000XM6 Sound Quality This is the other key area in which Sony holds an advantage, offering some of the best sound in the genre. To their credit, the QC Ultra are the best sounding Bose headphones I've tested, serving up impressive balance, clarity, and vibrancy. You'll find marked sensitivity and precision in the midrange and treble that evoke keen instrumental timbres and tight separation across the stereo image. Bass is mildly boomy by default but is easily tamed in the EQ. For those who enjoy it, Bose's pair holds a slight advantage for spatial audio. Both models offer 3D upmixing for more immersive listening with available head-tracking, which keeps your music centered as though listening to a pair of speakers, but Sony's head-tracking is limited to Android devices only, while Bose's pair works for either device type. For stereo playback, Sony's XM6 provides a warmer overall sound signature that still takes care with the higher frequencies, allowing for more intimacy, breadth, and instrumental textures that burst through the mix. Horns, woodwinds, and percussion are particularly gorgeous, with a lyrical, sometimes flinty brilliance that always steers clear of sharpness. The XM6's bass response is just as impressive. It's taut and poised while still letting loose with some extra thump that blends studio-style precision with some playful buzz and grit. Rolling through the latest Andy Shauf project, Foxwarren 2 , I was wholly enamored with the array of synth and percussion sounds, from the bouncy groove in 'Deadhead' to the sawtoothed grind of 'Havana.' Both models offer sound quality worthy of their price tags, but Sony's deeper dive into the details hooked me in the first few minutes and never let go. WIRED: Sony WH-1000XM6 Call Quality Both pairs fared well across a number of calls between friends and colleagues. It's always hard to judge calling accurately given factors like crappy Zoom calls or dodgy cell connections, but I had no trouble with either pair on my end, and everyone I talked to said they could hear me clearly, even in crowded areas. WIRED: Tie Battery Life Another slight strength for Sony, you'll get a max of around 30 hours of playback with noise canceling, just like the XM5, while Bose's pair offers a max of 24 hours with ambient modes engaged. It's worth noting that plenty of cheaper pairs provide more, but either number is plenty for all applications. WIRED: Sony WH-1000XM6 Which Pair Should I Buy? The answer here may seem obvious, with Sony's WH-1000XM6 taking more categories. For my money, their mix of great usability, improved sound quality, and instantly vaporizing noise cancellation makes them the wireless headphones to beat. Still, there's a good argument for Bose's QC Ultra, particularly for long-haul travelers. With better comfort, great sound, and similarly fabulous noise canceling, they remain top contenders. They also debuted at a lower price (though it's now in line with Sony on Bose's site) and can often be found on sale. Either way, you're getting insanely good noise canceling that bests everything else we've tested. Win-win! Power up with unlimited access to WIRED.

I convinced my dad to buy Bose QuietComfort headphones — now they're $100 off for Father's Day

A few months ago, when my dad asked me to recommend him a pair of the best headphones, I didn't hesitate. "Bose QuietComforts," I said. "They're pricey, but they're worth it." He placed an order that day, and now I look forward to visiting my parents not just to see them (although, that's the primary reason, of course), but also to use my dad's Bose QuietComfort headphones. As outlined in our Bose QuietComfort headphones review, the cans are extremely impressive. On top of ANC so good that no other brand even comes close, the headphones sound excellent in every single genre. And now? You can save a massive $100 on Bose QuietComfort headphones. The QuietComfort headphones are on sale in the following colors: black (pictured), dark blue, lilac, light blue, beige, and white. Green is the only color not on sale, which is a shame because it's actually gorgeous. Price check: $249 @ Best Buy | $249 @ Walmart I've personally used the Bose QuietComfort headphones, and I can admit that $349 is expensive for what you get. However, with $100 off, these headphones are competitively priced. Considering that most excellent Bluetooth headphones hover around $400 these days (what has the world come to?), $249 is about as low as you're going to get for Bose. What makes Bose gear so good is its ANC. My colleague Nikita described Bose's ANC better than anyone else: it's so good you feel lonely. Thankfully, when music sounds this good you can overlook the fact you're the only one listening. The QuietComfort headphones are bass-driven, with loud, groovy thumps across most genres. I'd recommend these headphones for serious bass lovers, or if you listen to genres like rock, hip-hop, or house. While I've never thought the QuietComfort headphones sound anything but fantastic, they genuinely excel with bassy tracks. However, you can also adjust and create custom EQs with the Bose Music app, should you want a little less bass in your listening. The Bose QuietComfort headphones come recommended for a reason, and at just $249, they're an absolute steal. I convinced my dad to buy these and he loves them, but now I wish I'd bought them for Father's Day instead!
