If you want active noise cancellation, a long 35-hour battery and a Bluetooth 5.4 connection that holds up at range, choose OpenListen NC09; if you need a simple, no-frills pair of noise isolation earbuds and you don't care about ANC, battery figures or codec-era specs, choose Generic Earbuds.
• OpenListen NC09 — biggest trade-off: It's the fussier product. Touch controls, an app-free feature stack, ANC and a charging case all mean more to learn and more to go wrong than a bare-bones pair.
• Generic Earbuds — biggest strength: Stripped-back simplicity. Passive sound isolation, no jack, Bluetooth wireless, and a protective case in the box. Nothing to configure.
• Generic Earbuds — biggest trade-off: The data sheet is thin. No ANC, no stated battery life, no stated Bluetooth version, no stated driver size. You're buying on faith more than spec.
• Who OpenListen NC09 is for: Anyone who commutes, flies, works in an open office, or takes a lot of calls and wants the earbuds to do the noise-blocking work for them.
• Who Generic Earbuds is for: Someone who just wants a pair of in-ear buds that isolate a bit of outside sound and otherwise stays out of the way — a backup pair, a gym spare, a "don't overthink it" purchase.
The NC09 is the more ambitious product of the two, and the spec sheet backs that up. The headline feature is Active Noise Cancellation — the earbuds actively cancel ambient noise rather than just blocking it with a physical seal. That distinction matters in practice. Passive isolation (what the Generic pair offers) only reduces noise by how well the tip plugs your ear canal. Active cancellation goes after the low, droning stuff that a seal alone struggles with: engine hum, air-conditioning, the rumble of a train.
Then there's the battery. OpenListen states an average life of 35 hours and a charge time of about one hour. Whether that 35 hours is per charge or with the case is worth confirming, but either way it's the only concrete battery figure between these two products — the Generic sheet states none at all. For a long-haul flight, a full workday plus a commute, or a weekend away without a charger, that number is the whole argument.
Connectivity is the other differentiator. Bluetooth 5.4 with a stated range of up to 15 metres and automatic pairing when you lift the buds from the case. In my opinion that's the single most underrated spec here: Bluetooth 5.4 generally means a more stable link and lower latency than older versions, which is what you want if you watch video or take calls. Speaking of calls, there are four built-in ENC microphones — environmental noise cancellation aimed at the person on the other end, not you. If you spend your day on Zoom or the phone in a noisy room, that's a real, tangible benefit.
Audio-wise, the sheet lists dual 14.2mm low-distortion composite dynamic drivers, with a 9D stereo framing and a claimed deep-bass, full-midrange, crisp-treble tuning. I'd treat the marketing language with a raised eyebrow, but the 14.2mm driver size is on the larger side for an in-ear bud, which usually translates to more low-end presence. There's also a 13mm driver mentioned in a second bullet — the sheet is inconsistent there, so don't buy it purely on driver specs.
Skip it if: you hate touch controls, you want the absolute simplest possible pair, or you don't actually need ANC and would rather not pay for it. Also skip if you need a wired connection — there's no jack here, same as the Generic pair.
Generic Earbuds: Who It's For
The Generic Earbuds are, frankly, a spec sheet with a lot of blank space. Model T16, pearl white, in-ear bud shape, Bluetooth wireless, no headphone jack, a protective case included, and "Sound Isolation" listed under noise control. That's essentially the whole story.
That's not automatically a bad thing. Sound isolation — passive isolation — is the physical kind: the bud sits in your ear and the tip blocks some outside noise. No batteries to manage for the cancellation, no processing, no modes to toggle. For a lot of people that's exactly enough. Sitting at a desk, walking a dog, lifting weights, watching something on a laptop — passive isolation handles a decent chunk of that, and it never runs out of ANC.
The pearl white finish is a meaningful practical difference from the NC09's black: white shows less fingerprint smudging on glossy plastic but more grime over time, and it's a different look if you care about aesthetics. The included protective case is a small but real plus — it suggests the charging case (or at least a carrying case) is part of the package.
What you can't tell from the sheet is the part that usually decides these purchases: battery life, Bluetooth version, driver size, microphone count, water resistance, weight, and whether "sound isolation" is genuinely passive or marketing shorthand. None of that is stated. That's the honest trade-off. You're buying a simpler, more anonymous product with fewer promises attached.
Buy it if: you want a cheap-feeling-risk, low-commitment pair of in-ears, you're a passive-isolation person rather than an ANC person, or you want a spare pair for a bag or a desk drawer. Skip it if: you need ANC for commuting or flying, you take a lot of calls in noisy places, you need a stated battery figure before you commit, or you want the newer Bluetooth standard for lower latency.
Side-by-Side: Which Should You Choose?
• Best for battery life → OpenListen NC09. 35 hours average life and roughly one hour to charge. The Generic sheet states no battery figure at all.
• Best for calls in noisy environments → OpenListen NC09. Four ENC microphones plus a dedicated call-cancellation bullet. The Generic pair lists no microphone detail.
• Best for connectivity and latency → OpenListen NC09. Bluetooth 5.4 with a stated 15-metre range and automatic pairing. The Generic pair says "Bluetooth" and stops there.
• Best for simplicity → Generic Earbuds. No touch-control layer, no ANC modes, no feature stack to learn. Take them out, they play.
• Best for low-commitment, spare-pair duty → Generic Earbuds. A protective case in pearl white and a passive design make it an easy second pair.
• Best for water resistance → OpenListen NC09, with a caveat. The sheet lists both IPX5 and IP7, so it's protected against sweat and splashes — but confirm the exact rating before you trust it near water.
• Best for sound detail on paper → OpenListen NC09. Larger stated dynamic drivers and a fuller tuning description. The Generic sheet gives you nothing to compare against.
I'd buy the OpenListen NC09. Not because the Generic Earbuds are bad — there's nothing wrong with a simple, passive-isolation in-ear — but because the NC09 is the only one of the two that tells me what I'm getting: ANC, 35 hours, Bluetooth 5.4, four call microphones, touch controls, a stated weight. The Generic sheet leaves too many of the questions I actually care about unanswered for me to recommend it as a primary pair.
If you're on a tight budget or you just want a cheap spare that isolates sound and nothing more, the Generic Earbuds are the reasonable pick — and honestly, they may suit you fine. But for commuting, flying, open-plan offices and calls, I think the NC09 earns its place. Check the current price on Amazon before you decide, since that's the one variable that can flip this call either way.
FAQ
how to noise cancelling earbuds
On the OpenListen NC09, noise cancellation is active — the earbuds use onboard processing to reduce ambient sound, and there's no separate mode switch described in the sheet beyond the listed Active Noise Cancellation control. The Generic Earbuds don't do this; their "sound isolation" is passive, meaning the tip physically blocks some outside noise. Put them in, and that's the full extent of the noise reduction.
how to noise cancelling earbuds work
how to use noise cancelling earbuds
Take the NC09 out of its charging case and they pair with each other automatically, then connect over Bluetooth 5.4 to your phone, tablet or laptop. Use the touch sensors to play, pause, skip tracks, adjust volume, answer calls or activate Siri. The Generic Earbuds are Bluetooth wireless with no jack, so you pair them the same way — but there's no ANC to activate, since they only isolate passively.
how to noise cancelling earbuds apple
Both pairs are Bluetooth wireless and the NC09 sheet explicitly lists compatibility with iOS devices, so an iPhone or iPad will pair normally — and the NC09's touch controls include Siri activation. The Generic Earbuds list no device compatibility details, but as a standard Bluetooth in-ear they should connect to Apple hardware the same way any Bluetooth bud does. Neither product is made by Apple, and neither is affiliated with Apple.
