The earbuds on the end are pretty standard, with eartips on one side and a flat back with magnets. When the buds are attached together, they will simply stop playing the audio, which you can resume once you put them back in. The Bullets Wireless Z2 are quite light and can be worn around the neck all day without ever feeling like a burden. The material used is quite skin-friendly and feels quite sturdy as well. It also comes with an IP55 rating.
Pairing the OnePlus Bullets Wireless Z2 is a pretty fuss-free process. All you have to do is press and hold the play/pause button, and the buds will go into pairing mode. You can then look up the buds in the list of Bluetooth pairings on your device and connect the buds. Once connected, the Bullets Z2 will connect to your phone automatically once you put them on.

You get the usual volume buttons on the buds and another button in the middle in terms of controls. Now instead of simply sharing the command load amongst its button comrades, OnePlus has put all the burden on this one button in the middle. Apart from the usual pairing/play/ pause/ call receiving/ call ending functions (which are already a lot for a single button), OnePlus has also made it responsible for changing tracks. You have to press the button twice to skip to the next song and thrice to go back to the last song. It may all sound simple but can actually be chaotic in practice as you have to keep track of how many times you have pressed that tiny button before the command is completed.

The OnePlus Bullets Wireless Z2 comes with the biggest drivers seen on a pair of OnePlus earphones- 12.4mm. The fact that OnePlus is offering such big drivers for under two thousand rupees is a major plus point for the buds. The earbuds support two audio codecs, SBC and AAC.

As for the audio performance, the Bullets Wireless Z2 are pretty loud and come with plenty of bass, something that seems to be every brand’s audio formula in the budget segment. While this kind of signature sound gives the audio some faux body, it actually fails to deliver what the audio is truly supposed to sound like.
If you are someone looking for a pair of earphones that offer balanced sound, then you might not like the sound profile that the Bullets Wireless Z2 offer as they lack balance, majorly.

That said, if you are someone who likes bass-heavy audio output and do not mind if some bass sneaks into your mids, then the OnePlus Bullets Wireless Z2 will definitely be your cup of tea.

The OnePlus Bullets Wireless Z2 were pretty good in terms of call quality. We could hear the speaker clearly, and we heard no complaints whatsoever regarding our audio quality while using the buds. As the buds fit deep into your ear canals, they offer really good passive noise cancellation.

They come with big 12.4 mm drivers, offer really long battery life, have a bass-heavy signature sound, and have a really solid build. But because the earbuds are really bass-heavy, they lack balance, and for those who like to listen to melodious or classical music, these might not be a great option.
The Bullets Wireless Z2 also face some heat from the likes of Oppo Enco M32 and the Realme Buds 2, which are priced in the same vicinity. The OnePlus Bullets Wireless Z2 are actually a great proposition for the price; you only need to have a liking for bass.

Amped-Up Audio:
Bass Bonanza: These earbuds live up to their “bombastic bass” claim. Low-end frequencies thump with gusto, giving your music a powerful punch. Bass lovers will be in sonic heaven.
Balanced Bites: But the Z2s aren’t just bass machines. Mids and highs come through clear and crisp, offering a surprisingly well-rounded soundscape for most genres.
Customization Cravings: While the default tuning is great, audiophiles can tweak the EQ via the OnePlus Buds app. This lets you tailor the sound to your personal preferences.
Charge Champs:
Warp Speed Refueling: The 10-minute charge for 20 hours of playback is no gimmick. This lightning-fast charging is a life-saver for those on-the-go.
Marathon Mojo: The 30-hour battery life is equally impressive. Say goodbye to constant charging anxieties and enjoy music, podcasts, and calls all day long.
Bumpy Bits:
Fit Fiesta (or Fizzle): The neckband design might not be for everyone. While it’s comfortable for some, others might find it bulky or awkward. Finding the right fit for the ear tips can also be tricky.
Mic Mishaps: Call quality can be inconsistent, with muffled audio on the other end at times. This might be a deal-breaker for those who rely heavily on hands-free calls.
App Apathy: The OnePlus Buds app, while offering EQ customization, feels limited compared to competitor apps. More features and functionalities would be welcome.
Verdict:
The OnePlus Bullets Z2 are a potent package of powerful bass, rapid charging, and epic battery life. They’re a great choice for bass-loving music enthusiasts who prioritize convenience and long-lasting playtime. However, the neckband design might not be universally comfortable, and call quality can be hit-or-miss. Consider your priorities and try them out for yourself before diving in.

Remember: Everyone’s experience is different. These are just my impressions based on my usage.
I hope this review helps you decide if the OnePlus Bullets Z2 are the earbuds for you!

Sound quality is ok, lower than Soundmagic E11C. Bass is like always present; it’s like it drowns the other frequencies.

It does not autoswitch to other device. This is a BIG let down.
What I mean is it can connect and store 2 device in it’s memory. But it can not simultaneously keep the connection alive with 2 devices. For example, if you’re watching/listening from laptop, and your phone rings. You need to press the top button twice to connect to the phone & then you can receive the call. Also after switch your laptop playback is not paused. It’s really annoying. Even my 2019 xiaomi wireless can auto switch & do all this play/pause tricks.

Enriches sounds no doubt.👍
