• OPPO Enco Air5 — biggest strength: 55dB active noise cancellation across a 5000Hz ultra-wide range, plus Hi-Res Audio with LHDC 5.0 and up to 54 hours of total playback. That is a lot of headphone for one pair.
• OPPO Enco Air5 — biggest trade-off: It is the more feature-loaded, more expensive-feeling option of the two, and its IP55 rating is sweat-and-rain resistant rather than fully submersible. If you want a cheap knockabout pair you can lose in a gym bag, this is more earbud than you need.
• ZZU Earbuds Bass — biggest strength: A 13.2mm dynamic driver tuned for deep bass, IPX7 waterproofing and a dual LED display that shows exactly how much charge is left. Light at 0.13 oz per bud, too.
• ZZU Earbuds Bass — biggest trade-off: Bluetooth 5.3 instead of 6.0, no hi-res codec, and a shorter 48-hour total runtime. It is the simpler tool.
• Who each is for: OPPO Enco Air5 → commuters, call-heavy workers and anyone who wants silence on demand. ZZU Earbuds Bass → runners, lifters and budget-focused buyers who want thump and don't care about codecs.
The OPPO Enco Air5 Pro is built around one idea: shut the world out. Its 55dB active noise cancellation works across a 5000Hz ultra-wide frequency range, and the real-time dynamic ANC adapts to your ear canal and your surroundings. In plain terms, it is aiming at the noises that actually ruin your day — engine drone on a train, air conditioning hum, the low murmur of an open-plan office. The spec sheet specifically calls out human voices and ambient chatter as targets, which is the hardest part of noise cancelling to get right.
Sound-wise, there is a 12mm titanium-coated dynamic driver with a PET titanium-plated diaphragm. Titanium plating is a stiffness trick: a stiffer diaphragm moves faster and settles quicker, which is why the description promises fast transient response and "punchy, authoritative bass" rather than a soft, bloated low end. On top of that you get Hi-Res Audio certification with LHDC 5.0 supporting up to 96kHz sampling and a 1Mbps wireless bitrate — genuinely higher-resolution transmission than standard Bluetooth codecs — plus OPPO Alive Audio for a 360° soundstage and a Sound Master EQ for tuning things your way.
Buy it if you commute, take a lot of calls, or work somewhere noisy and you want the noise to disappear. Skip it if you mainly want a cheap pair for sweaty workouts and you would rather not pay for ANC, hi-res codecs and translation features you will never touch.
ZZU Earbuds Bass: Who It's For
The ZZU Earbuds Bass takes the opposite approach: keep it simple, keep it light, and put the money where you feel it. The headline is a 13.2mm dynamic driver — physically larger than the OPPO's 12mm — delivering what the sheet describes as rich Hi-Fi stereo with deep bass, clear vocals and crisp treble. A bigger driver moving more air is the classic route to that chesty low end people mean when they say "bass." It is not chasing hi-res certification. It is chasing thump.
The rest of the package is built for movement. IPX7 waterproofing is a step above IP55 — that rating means it survives immersion, not just splashes, so sweat, rain and a rinsed-off bud after a run are all fine. Each earbud weighs 0.13 oz, and three sizes of silicone tips are in the box, so long sessions should not turn into ear-ache. Bluetooth 5.3 with a 33-foot range and 60ms latency covers the basics: fast pairing, a stable connection, and audio that stays in sync with video well enough for everyday watching.
Two details stand out for daily life. First, the dual LED digital display on the case, which shows remaining case power and each earbud's charging status — no guessing, no surprise dead bud. Second, the numbers: up to 9 hours on a single charge and up to 48 hours total with the case, recharged over USB-C in about 2 hours. The case itself is compact at roughly 3 x 2.5 x 1.5 inches and about an ounce.
Buy it if you want deep bass, a secure lightweight fit, real waterproofing and a visible battery readout without overthinking it. Skip it if you need strong active noise cancellation, the latest Bluetooth version or high-resolution codecs — those are not what this pair is built for.
• Best for noise cancellation → OPPO Enco Air5. 55dB ANC across a 5000Hz range versus a bass-first tuning on the ZZU.
• Best for pure bass punch → ZZU Earbuds Bass. A 13.2mm driver against the OPPO's 12mm, and bass is literally the product's name.
• Best for battery life → OPPO Enco Air5. Up to 54 hours total versus up to 48 hours, with 9 hours per charge on the ZZU.
• Best for workouts and rain → ZZU Earbuds Bass. IPX7 beats IP55 for sweat, rain and rinsing.
• Best for calls → OPPO Enco Air5. Triple-mic AI clear-call with wind handling up to 25 km/h is a much more serious call setup.
• Best for audio quality and codecs → OPPO Enco Air5. Hi-Res Audio, LHDC 5.0, 96kHz and a 1Mbps bitrate are a different tier.
• Best for connection flexibility → OPPO Enco Air5. Bluetooth 6.0 and Dual Connection across Android, iOS and Windows.
• Best for a lightweight, uncomplicated fit → ZZU Earbuds Bass. 0.13 oz per bud, three tip sizes, LED battery display.
• Best value for casual use → ZZU Earbuds Bass. In my opinion, if you just want bass and waterproofing, the ZZU covers the essentials without extras you won't use.
I would buy the OPPO Enco Air5. In my opinion, the combination of 55dB ANC, a titanium-coated 12mm driver, Hi-Res Audio with LHDC 5.0, Bluetooth 6.0 with Dual Connection and up to 54 hours of playback makes it the more complete pair for most people's actual day — commuting, working and calling. The ZZU Earbuds Bass is a genuinely appealing pick if deep bass and IPX7 waterproofing are your whole checklist, and it wins on simplicity. But if you can only own one, the OPPO does more, and does it across more situations. Check the current price on Amazon before you decide, since that is the one variable that could flip this call for you.
FAQ
how is deep bass earbuds
how to turn up bass on earbuds
First, check for a companion app or an in-app equalizer — the OPPO Enco Air5 includes Sound Master EQ for personalized tuning, so that is your first stop. Then try better ear tips and a tighter seal, because a poor seal leaks bass away. The ZZU ships with three silicone tip sizes precisely so you can find that fit.
what is deep bass earbuds
Deep bass earbuds are in-ear models engineered so the low end extends lower and hits harder than a flat or neutral tuning would allow. Usually that means a larger dynamic driver, a good seal in the ear canal, and sometimes software EQ. The ZZU's 13.2mm driver and the OPPO's 12mm titanium-coated driver are both examples of that design thinking.
is deep bass earbuds good
Yes, if you listen to bass-heavy music, watch action movies or want energy in the gym — a strong low end makes those far more enjoyable. The trade-off is that heavy bass tuning can soften detail in the mids and highs, which is why the OPPO's Hi-Res Audio and LHDC 5.0 support matter if accuracy is also a priority for you.
