The OnePlus Buds 4 Zen Green are OnePlus’s flagship noise cancelling earbuds in the lighter of the two official colours. Zen Green is a soft, muted green on both the earbuds and the case, calmer than a bright colour but clearly different from the usual black and white. Underneath it is the full OnePlus Buds 4 package: up to 55dB of adaptive noise cancelling, an 11mm woofer and 6mm tweeter with their own DACs, and tuning tools that let you shape the sound to your ears. This page focuses on those tuning tools and on active use.

The OnePlus Buds 4 Zen Green Colour
Zen Green is a gentle, slightly grey green rather than a loud one. On the OnePlus Buds 4 Zen Green it covers the stems, the buds and the pebble-shaped case, so the set looks coordinated on a desk or in the hand. It pairs well with neutral clothing, sportswear and light-coloured phones, and it is easy to spot in a gym bag.
The lighter shade of the OnePlus Buds 4 Zen Green shows more than a dark one. Dust and skin oils are more visible on the stems and around the lid hinge, so give the case and buds a wipe with a dry, soft cloth every few days, and clean the ear tips separately. Keep the case away from pens and keys in the same pocket to avoid marks.
If you would rather have a darker, low-key finish, the same earbuds are available in Storm Gray.
Tune the Sound: BassWave 2.0, EQ and Golden Sound
The OnePlus Buds 4 Zen Green give you more control over sound than most earbuds. Sound Master EQ has three presets, Balanced, Serenade and Bass Mode, and a customisable six-band EQ for anyone who wants to fine-tune. BassWave 2.0 adds bass enhancement on top, for more impact in hip-hop, electronic music and film soundtracks.
Golden Sound goes further. It runs an ear scan and a short listening test, then builds a personal audio profile for your ears. OnePlus 3D Audio adds a spatial effect that places sound around you. On OnePlus phones with Android 12 or later these are in the Earbuds Function settings; on other Android phones (Android 7.0 or later) and on iPhone they need the HeyMelody app.
The hardware behind it is a dual-driver setup: an 11mm woofer with a 30-layer ceramic-metal diaphragm and a 6mm flat-diaphragm tweeter, each with its own DAC, plus LHDC 5.0 support at up to 24-bit/192kHz on compatible Android phones.
Built for Active Days
The OnePlus Buds 4 Zen Green earbuds are rated IP55 against dust and water, which covers sweat and rain on a run or at the gym. The case is not rated, so keep it in your bag. OnePlus also notes that water and dust resistance can reduce with age and that liquid damage is not covered by its warranty.
For outdoor sessions with the OnePlus Buds 4 Zen Green, Adaptive mode is the useful one: it switches between noise cancelling and Transparency automatically, so you hear cars, bikes and alarms when you need to. For the gym floor, full ANC shuts out the music from the speakers so you can hear your own.
Gaming, Video and Translation
A 47ms low-latency mode keeps audio in step with games and video. It turns on automatically with OnePlus phones and can be enabled in the HeyMelody app with other brands. Dual-device connection lets the earbuds stay paired with a phone and a laptop at the same time.
With select OnePlus phones running OxygenOS 15.0.1 or later, a triple tap starts AI Translation for real-time conversation in dozens of languages. Voice assistant access works on any phone with a built-in assistant once set up.
The Rest, in Brief
Noise cancelling up to 55dB within 5,500Hz (OnePlus lab data). Battery at 50% volume: up to 11 hours from the buds and 45 hours with the case with ANC off (AAC); 6 and 24 hours with ANC on. Ten minutes of charging gives up to 11 hours including the case. Bluetooth 5.4, Google Fast Pair, three microphones per bud, USB-C wired charging.
Who This Is Not For
If you use an iPhone and care most about Hi-Res audio, note that LHDC works only on supporting Android phones. AI Translation and Steady Connect need select OnePlus phones.
If you want wireless charging, OnePlus does not list it. If you want a case that survives rain too, only the earbuds are IP55. And if you know you will not clean your earbuds regularly, Storm Gray hides wear better than Zen Green.
