OnePlus Bullets Wireless Z3 review: Budget neckband with big bass, bigger battery

The sub- ₹2,000 wireless audio segment in India is fiercely competitive, with dozens of brands offering flashy features and bargain prices. But the OnePlus Bullets Wireless Z3, launched at ₹1,699, makes a bold case for itself, not just on specs, but with a fine-tuned balance of performance, comfort and battery life. With features like BassWave tech, 3D Spatial Audio, and fast charging that defies logic, the Z3 shows that budget doesn't have to mean basic.
After using the Bullets Wireless Z3 for over a week across workouts, travel and long Zoom calls, here's our verdict on whether this neckband deserves your attention, and your money.
OnePlus has stuck to a tried-and-tested neckband design for the Bullets Wireless Z3, but with some nice touches. The finish is smooth and skin-friendly, the neckband flexes easily, and the magnetic earbuds snap together to pause audio or power off, a small but thoughtful detail.
At just under 30 grams, the Z3 is lightweight enough for all-day wear, and the IP55 water and dust resistance gives you peace of mind during sweaty workouts or unexpected rain. It's available in two colours, Mambo Midnight (black) for the minimalists and Samba Sunset (red) for those who want a bit more flair.
The Z3 doesn't shy away from bass. Its 12.4mm drivers and BassWave algorithm deliver a thumpy, energetic sound that's perfect for bass-heavy genres like EDM or hip-hop. What's impressive is that even with the strong low-end, the vocals remain clear and highs are crisp enough for podcasts or acoustic tracks.

What really elevates the experience is Sound Master EQ. The four presets, Balanced, Serenade, Bass, and Bold, cater to different tastes and situations. Whether you want subtle background tunes while working or heart-thumping beats for a run, you'll find a profile that fits.
It's not audiophile-grade by any means, but for under ₹2,000, this is easily among the best sounding Bluetooth neckbands you can buy.
OnePlus is going beyond just sound with the Z3. One of the headline features is 3D Spatial Audio, which gives you a wider, more immersive soundstage when watching videos or playing games. It's a noticeable upgrade from basic stereo, especially when used with supported apps or formats.
Then there's AI Call Noise Cancellation, which genuinely works. During our tests in traffic-heavy areas and crowded cafes, the person on the other end could hear us clearly, with most background noise filtered out.
Add to that a Voice Assistant Shortcut, activated via the in-line remote, and you've got a device that feels smarter than its price tag suggests.
If there's one area where the Bullets Wireless Z3 truly shines, it's battery life. OnePlus claims 36 hours of playback on a full charge, and we consistently got over 32–34 hours with mixed use (including calls and moderate volume music).
But here's the kicker: just 10 minutes of charging gives you up to 27 hours of playback. That's not a typo. In real-world use, even a short top-up before heading out can keep you going for days.
Call time is equally impressive at up to 21 hours, making the Z3 a genuine all-day, every-day neckband for work or travel.
With Bluetooth 5.4, Google Fast Pair, and support for quick auto-connect when separating the magnetic buds, connectivity on the Z3 is snappy and reliable. Pairing took mere seconds, and we experienced zero dropouts even while switching between devices.
Controls are via a traditional in-line remote with physical buttons for volume, playback, and calls. They're tactile and easy to find by touch, which is great if you don't want to fiddle around during a jog or while commuting.
At ₹1,699, the OnePlus Bullets Wireless Z3 is nothing short of a steal. It's rare to see this level of polish, sound quality, and battery life at this price point. Whether you're a student, a commuter, or someone who just prefers the classic neckband format over true wireless earbuds, the Z3 is an absolute no-brainer.
Sure, there's no ANC and the sound may not be detailed enough for hardcore audiophiles, but for the vast majority of users, these are more than good enough.
If you're looking for a dependable, feature-packed neckband under ₹2,000, this might be the best one yet.

Best True Wireless (TWS) Earbuds under Rs 12,000 in India on World Music Day 2025

From OnePlus Buds Pro 3 to Sony Linkbuds S, here are the best earphones under USD 150 in India at the moment read more On this World Music Day, we bring you a list of TWS earphones priced up to Rs 12,000 in India that offer not just excellent sound quality but a great feature set too. All these earbuds from notable brands offer features like ANC (active noise cancellation), multi-point connectivity, wear detection and useful companion apps to explore their full potential. And the price cuts on some of these generally more expensive models will be music to your ears. So let's begin. STORY CONTINUES BELOW THIS AD Best TWS earbuds under Rs 12,000 in India Price: Rs 10,999 What's good about it: Excellent sound quality with good balance and detail Customisable sound and controls through the app Combination of pinch and slide controls works well Wear detection sensors, volume control on the buds Comfortable fit, elegant design Support for LHDC 5.0 codec and Google Spacial Audio Very good battery backup, supports wireless and fast charging Good call quality, multipoint support What's not: OnePlus Buds Pro 3 No ingress protection for the charging case this time No support for more popular LDAC or aptX codecs After two mixed attempts, OnePlus got their act in order with its current flagship Buds Pro 3. Despite its 10K+ price tag, we believe it is the best value-for-money product in the semi-premium category of TWS earbuds that can take on anything priced under 15K at the moment. There is a marked improvement in performance as compared to its predecessor. Be it sound quality, call quality, ANC, battery life or user experience, the OnePlus Buds Pro 3 is better on all counts. It supports wireless charging too. The dual-driver setup and Dynaudio's tuning is a great combination that handles the three major frequency ranges quite well and produces tight and punchy bass, detailed midrange and sharp highs. There are ample sound tweaks available though the companion app to fine-tune it further. The slide gestures in addition to pinch controls on the earbuds give great control over its various functions. Add to that a robust battery backup of up to 30 hours, very good call quality and we have an excellent all-round product that's hard to beat in this budget. Price: Rs 11,999 What's good about it: Balanced and detailed sound output Good codec support Attractive design, comfortable in the ears Buds and case are both splash resistant Lots of sound tweaks in the companion app Good call quality, dual pairing support Good battery backup with support for fast charging and wireless charging What's not: Average active noise cancellation and transparency STORY CONTINUES BELOW THIS AD Battery backup with ANC on could have been better Nothing Ear The Nothing Ear which is the successor to Nothing Ear (2) – don't bother with the numbering system – is another great option in this segment for its trademark transparent design, sound quality and feature set. Though it looks exactly like its predecessor, there are a bunch of minor enhancements and a major one - support for the more popular LDAC codec in addition to LHDC for higher throughput. The sound quality is quite impressive with tight and punchy bass, good midrange response, crisp vocals and perfectly tempered highs that retain ample sparkle without sounding sibilant. There is a good amount of detail in the audio, and the fairly broad soundstage enhances the overall experience. And you also get a ton of sound tweaks in the companion app – in fact, the most we have seen across brands – that let you adjust minute details in the audio. STORY CONTINUES BELOW THIS AD There are improvements across the board, be it sound quality, codec support, battery backup or ANC. The Nothing Ear supports wireless charging as well as fast wired charging. There's ChatGPT integration too, and one can use their voice to access it after setting it up through the Nothing X app. With such a stacked feature set and impressive sound quality, one may not mind paying a bit of a premium for the Nothing Ear. Best TWS earbuds under Rs 10,000 in India Price: Rs 9,990 What's good about it: Good sound quality Compact design, comfortable in-ear fit Impressive ANC and ambient mode Wear detection, multipoint support Support for LDAC codecs even when paired with two devices Useful companion app Good battery backup with ANC on What's not: Touch controls configuration could have been smarter Average call quality Sony LinkBuds S WF-LS900N The Sony Linkbuds S WF-LS900N was priced at Rs 16,990 at launch where some of its shortcomings were amplified. But under 10K, it is an excellent option. Not only do these earbuds sound good but also offer the best ANC in this segment and an equally impressive transparency mode. You can use the LDAC codec even if you pair these buds with two devices simultaneously. The fit and comfort at top class and you also get wear detection sensors. STORY CONTINUES BELOW THIS AD The Sony Linkbuds S does sound very good out of the box but you can fine tune the output further to your liking using the Sony Headphones app that offers a handful of more tweaks. The battery backup may not be as high as some of the other buds in this list but you get 20 hours with ANC switched on all the time, which is commendable. With all the key boxes ticked, excellent sound and ANC and a price drop, the Sony Linkbuds S WF-LS900N is a straightforward recommendation. Price: Rs 7,299 What's good about it: Enjoyable sound output across various genres of music Support for LDAC, aptX Adaptive/ Lossless codecs and more Hi-Res Audio and Snapdragon Sound certified Loads of sound and ANC customisations Improved active noise cancellation and transparency Comfortable in-ear fit, good passive noise isolation Wear detection sensors, Auracast, dual pairing support Impressive battery backup, supports wireless charging 18 months warranty What's not: Touch sensitivity can be dodgy at times STORY CONTINUES BELOW THIS AD Noise suppression in calls needs improvement EarFun Air Pro 4 When it comes to feature-rich products, the lesser known EarFun Air Pro 4 is right up there with the very best at a much more competitive price. It also packs a punch when it comes to performance. These earbuds are Hi-Res Audio and Snapdragon Sound certified and support LDAC as well as aptX Lossless and aptX Adaptive codecs. The sound quality is very good for the segment, and if you do not like the default sound, the companion app lets you tweak it further using a multi-band equaliser or a bunch of presets. Even better, the company shares the EQ config of its audio presets, and you can make minor adjustments to a preset that you like using the equaliser, rather than starting from scratch and indulging in guesswork to recreate a similar sound profile, as is the case with most audio products. The company has also added wear detection sensors that were missing on its previous products. ANC and call quality see a significant improvement too. STORY CONTINUES BELOW THIS AD The overall battery backup is commendable, ranging between 30 to 45 hours with and without ANC respectively. This product also supports wireless charging, dual pairing and Auracast. All of the above make the Earfun Air Pro 4 the most feature-rich product even in a segment or two higher, and with a solid all-round performance and sound quality, an easy recommendation if you have a budget of Rs 7,500. Price: Rs 5,999 What's good about it: Impressive sound quality courtesy of Bose Configurable sound and controls through companion app Comfortable in-ear fit, wear detection sensors IP54 ingress protection for the buds, IPX4 for the case Good call quality, dual pairing support Good battery backup with ANC off Supports wireless charging and fast charging What's not: Minor bugs that also include a moody Transparency mode No LHDC codec support on most phones Moto Buds+ Just like the Sony Linkbuds S, the Moto Buds+ has also seen a big price drop. At its current selling price of Rs 5,999, these tuned-by-Bose earbuds are a great buy even with its minor quirks for those looking for excellent sound quality under 6K. While these earbuds support LHDC codec, you may have to make do with AAC on most phones. But that doesn't stop them from sounding good, and the companion app offers you more tweaks. STORY CONTINUES BELOW THIS AD You get an overall battery backup of 22 hours with ANC on and 34 hours without it. To sum it up, the Moto Buds+ is a highly enjoyable pair of TWS earbuds with an elegant design, impressive feature list and sound quality, very good call quality, competent battery backup and support for dual pairing and wear detection. And let's not forget the 'Sound by Bose' branding that one can flaunt at a fraction of the cost of most Bose TWS earbuds. If you do not wish to spend as much and are yet looking for high quality wireless earphones around Rs 5,000, you should check this out .

OnePlus To Launch Gaming Smartphone With Shoulder Triggers

The upcoming model will compete with gaming phones like the Asus ROG Phone 9 Pro, Red Magic 10 Pro and Red Magic 10 Pro+ in the Chinese market. OnePlus is preparing to launch two new phones in India – the Nord 5 and Nord CE 5 – on July 8.
