How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life and bass-forward sound for long Xbox sessions, choose OnePlus Bullets; if you need a lighter, more flexible neckband with clearer hands-free calls and app-based tuning, choose Sony WI-C100. That's the short version. The long version comes down to how you actually wear these things — because neither of these is a dedicated wireless headset for Xbox, and knowing what each one really does well matters more than picking the "better" brand.
• OnePlus Bullets — biggest strength: Up to 30 hours of playback on a single charge, plus a 10-minute top-up that gets you up to 20 hours. For gaming headphones for Xbox that you'll wear for hours at a time, that's the standout number here.
• OnePlus Bullets — biggest trade-off: No noise control and no companion app, so the sound signature is whatever OnePlus tuned — a bass-heavy one — and you can't adjust it.
• Sony WI-C100 — biggest strength: A flexible neckband, a very light build at under 20 g, and the Sony | Headphones Connect app for fine-tuning your sound.
• Sony WI-C100 — biggest trade-off: Up to 25 hours of playback, and its quick charge gives you up to 60 minutes from 10 minutes — noticeably less headroom than the OnePlus.
• Pick OnePlus Bullets if you want maximum battery and deep bass for long gaming and music sessions.
• Pick Sony WI-C100 if you want the lighter, more flexible fit and clearer calls for everyday use.
The OnePlus Bullets Wireless Z2 is built around two ideas: big bass and big battery. The 12.4 mm dynamic driver is on the large side for an in-ear neckband model, and OnePlus pairs it with a titanium-coated dome and anti-distortion processing to keep things clean when the low end is working hard. In practice, that means this is a set tuned for punch — think kick drums, explosions, and the low rumble in a game's soundtrack. If your idea of a good time is feeling the bass rather than hearing a perfectly neutral mix, this is the personality you're getting.
The battery is the headline. Up to 30 hours on a charge, up to 16 hours of talk time, and 80 hours of standby. The quick-charge claim is genuinely unusual: a 10-minute charge for up to 20 hours of playback. OnePlus notes these figures come from its own test lab and that real-world results vary with charging and environmental conditions, so treat them as best-case — but even discounted, that's a lot of listening per charge. Charging to full takes about 25 minutes.
Build-wise, it's IP55 rated, so sweat and splashes are fine, and the silicone tips come in three sizes with an ergonomically curved shape. It's 27 g, uses touch controls for volume, and runs Bluetooth 5 with a 10-metre range.
Who should buy it: Anyone who wants long battery life with a bass-forward sound and doesn't mind a slightly heavier neckband. Who should skip it: If you want to EQ your sound or need active noise cancellation, there's none here — and there's no app to change anything.
The Sony WI-C100 takes the opposite approach. Instead of chasing big numbers, it leans on flexibility and convenience. The neckband is designed to bend so it slips into a bag easily, and at 19.87 g it's the lighter of the two — a real difference if you wear a set for hours. The earpieces use a rounded-tip shape with silicone plastic housing, and Sony explicitly notes that fit matters: if the tips don't seal your ear canal properly, both sound quality and call performance suffer, so swapping to a snugger tip is part of getting the most out of them.
Sound here is more about restoration than thump. DSEE — Sony's Digital Sound Enhancement Engine — works to rebuild high-frequency detail that gets stripped out when music is compressed, aiming for something closer to the original recording. It's a different philosophy from the OnePlus's bass emphasis, and it's the kind of thing you notice more on acoustic tracks and vocals than on a bass drop.
The other half of the pitch is usability. The physical buttons play, pause, skip tracks, adjust volume and take calls, and Sony redesigned them with a more pronounced shape so they're easier to find and press without looking. The built-in mic is tuned for clear hands-free calling. You also get the Sony | Headphones Connect app for fine-tuning, plus fast pairing with a simple tap on Android. Battery is up to 25 hours, with a 10-minute charge giving up to 60 minutes of playback. It's IPX4 rated — splash- and sweat-proof — and runs Bluetooth 5 with a 10-metre range.
Who should buy it: People who prioritize a light, flexible fit, easy button control and clear calls, and who like the idea of adjusting sound in an app. Who should skip it: If you want the longest possible battery or a strongly bass-led tuning, the OnePlus is the better match.
Side-by-Side: Which Should You Choose?
• Best for bass-heavy listening → OnePlus Bullets. The 12.4 mm driver and bass-first tuning are the point of the design.
• Best for long gaming sessions → OnePlus Bullets. That battery headroom is what makes it a sensible pick as a wireless headset for Xbox for marathon sessions, provided you're connecting over Bluetooth.
• Best for all-day comfort → Sony WI-C100. At under 20 g with a flexible neckband, it's the lighter, more packable option.
• Best for calls → Sony WI-C100. Clear hands-free calling is an explicit design focus, and the reshaped buttons make answering easier.
• Best for sound customization → Sony WI-C100. The Headphones Connect app and DSEE give you levers the OnePlus simply doesn't have.
• Best for water resistance → OnePlus Bullets. IP55 versus IPX4 — a step up in dust and water protection.
• Best for control style → depends. Touch controls (OnePlus) versus physical buttons (Sony). If you like pressing real buttons without looking, Sony wins; if you like taps, OnePlus.
In my opinion, the OnePlus Bullets Wireless Z2 is the one I'd buy for a bass-forward, long-session setup — the 30-hour battery and 10-minute/20-hour quick charge are the specs that would matter most to me, and the IP55 rating adds a bit of durability insurance. For gaming headphones for Xbox use over Bluetooth, that battery life is the deciding factor. That said, if comfort, button controls and app-based tuning rank higher for you than raw battery, I'd point you to the Sony WI-C100 instead. Check the current price on Amazon before you commit, since that's the one thing that can flip this call.
FAQ
Yes, on paper. OnePlus rates it at up to 30 hours with a 10-minute charge giving up to 20 hours, while Sony rates the WI-C100 at up to 25 hours with a 10-minute charge giving up to 60 minutes. OnePlus's figures come from its own lab and will vary in real use.
No. Neither headphone has noise control — the OnePlus lists noise control as none, and the Sony doesn't offer ANC either. Both are passive-isolation in-ears, so fit matters for how much outside sound you block.
Sony makes clear hands-free calling an explicit feature of the WI-C100 with its built-in mic, so if calls are a priority, that's the one I'd lean toward. OnePlus quotes up to 16 hours of talk time, which is a battery figure rather than a call-quality claim.
Both are Bluetooth 5 in-ear headphones with a 10-metre range, so they'll pair with Bluetooth-capable devices. Neither is a dedicated gaming headset, so if you want console-specific features, check your setup's Bluetooth support before buying — and weigh battery life and fit as your main criteria.
