If you want featherlight true-wireless earbuds with active noise-cancelling microphones for calls and workouts, choose CCA ND Pulsar True; if you need a foldable over-ear headphone that can stay connected to two devices at once for long desk and commute sessions, choose SENECESLI Over Ear Headphones.
• CCA ND Pulsar True — biggest strength: a genuinely small, light in-ear design (4.9 g per bud, 45° ergonomic angle, four ear tip sizes) with Bluetooth 5.4, a 13 mm dynamic driver and a four-microphone call system rated to cut up to 83% of background noise.
• CCA ND Pulsar True — biggest trade-off: it's an in-ear bud, so it relies on a snug tip seal, and its 5-hour-per-charge figure means you'll be reaching for the case on longer days.
• SENECESLI Over Ear Headphones — biggest strength: a foldable, adjustable over-ear build with a high-elastic headband, breathable protein-leather cushions, Bluetooth 6.0 and dual-device connectivity in a 220 g package.
• SENECESLI Over Ear Headphones — biggest trade-off: the spec sheet doesn't state a driver size, codec list or an hour rating, so you're buying comfort, portability and dual pairing rather than a documented audio or battery number.
• Pick CCA ND Pulsar True if you want something you forget you're wearing and you take a lot of calls on the move.
• Pick SENECESLI Over Ear Headphones if you want one headset parked on your head all day, flipping between a laptop and a phone.
The Pulsar True is built around a single idea: get the hardware out of your way. Each earbud weighs 4.9 g, which is about as close to "nothing" as an in-ear gets, and the 45° angled nozzle plus four ear tip sizes is the kind of detail that matters more than any spec sheet number — a bad seal kills bass and lets the outside world in, so having four sizes to choose from is a real practical advantage.
Inside, you get a 13 mm bio-composite dynamic driver, a frequency range of 20 Hz to 20,000 Hz, and tuning that CCA describes as bass-forward with crisp highs and balanced mids. There's also a spatial audio layer in the feature list. I'd read that as: this is a fun-sounding bud aimed at playlists, games and movies rather than flat studio monitoring. The Bluetooth 5.4 chip handles pairing and reconnection, and the range is a standard 10 metres.
The part that separates it from most cheap buds is the microphone array. Four mics with noise cancellation, quoted at blocking up to 83% of background noise and reducing wind interference by 32 dB, is a serious claim for a bud this small. If you take calls while walking a busy street, riding a train or moving through a gym, that's the feature you're actually paying for. Battery-wise you get around 5 hours per charge and up to 36 hours with the case, and a 30-minute Type-C top-up gives you hours back.
Buy it if you want an in-ear you can wear for hours without noticing, you care about call clarity in noisy places, or you train and commute with a phone in your pocket. Skip it if you hate things inside your ear canal, you want a headband-style fit, or you need a documented all-day single-charge runtime — five hours is five hours.
The SENECESLI is the opposite philosophy. It's an over-ear, 220 g headphone in black, with ABS/PC shells and protein-leather cushions. On paper that's a light over-ear — plenty of full-size cans sit well above that — and SENECESLI leans hard into that in the marketing: a "soft, skin-friendly wrap-around feel," a high-elastic headband that adjusts without pressure, and breathable ear cushions. For anyone who's worn a tight headband for three hours and felt it, those details are the whole pitch.
The connectivity story is the standout. It runs Bluetooth 6.0 with roughly 10 metres of range and support for A2DP, AVRCP, HFP and HSP — the standard protocol set that covers music playback, track and volume control, hands-free calls and headset operation. More interesting is dual-device connectivity: it holds two connections at once, so you can be on a laptop call and have your phone ring without repairing anything. If you bounce between a work machine and a personal phone all day, that's a genuinely useful feature that earbuds in this class rarely offer.
It folds. The earcups collapse so it travels flat in a bag, and the box includes a USB cable and a user manual. Battery is a 200 mAh lithium-ion cell that SENECESLI describes as lasting through a day of commute, travel, office or home listening — note that no hour figure is published, so treat that as a design intent rather than a number. There's also a 90-day manufacturer warranty.
Buy it if you want one headset for desk work, calls and commuting, you value a foldable over-ear that won't clamp your head, or you need two devices connected simultaneously. Skip it if you need earbuds for the gym, you want published battery and driver figures, or you prefer an in-ear seal for blocking noise.
• Best for call clarity in noise → CCA ND Pulsar True. Four mics, up to 83% background noise reduction and 32 dB wind handling is the most specific audio claim in either sheet.
• Best for all-day wear comfort → SENECESLI Over Ear Headphones. 220 g, adjustable high-elastic headband and breathable cushions are designed for long sessions without pressure.
• Best for workouts and running → CCA ND Pulsar True. 4.9 g per bud, a 45° ergonomic angle and four tip sizes make a secure fit far more likely than a 220 g headband.
• Best for switching between laptop and phone → SENECESLI Over Ear Headphones. Dual-device connectivity is simply not something the Pulsar offers.
• Best documented battery numbers → CCA ND Pulsar True. 5 hours per charge, 36 hours with the case, 30-minute fast charge. SENECESLI publishes only a 200 mAh cell.
• Best for travel packing → SENECESLI Over Ear Headphones. It folds flat; the Pulsar's case is pocket-sized but still a case.
• Best for sound hardware detail → CCA ND Pulsar True. A named 13 mm bio-composite driver with a stated 20 Hz–20 kHz range versus no published driver size.
• Best for a single do-everything headset → SENECESLI Over Ear Headphones, as long as you don't need it in the gym.
In my opinion, most people shopping this pair should buy the CCA ND Pulsar True. It publishes more of what actually matters — driver size, frequency range, microphone performance, real battery figures — and its 4.9 g in-ear design makes it the one you'll actually wear at the gym, on a call and on the walk home. I'd only steer you to the SENECESLI if your day is built around a desk, a laptop and a phone, because dual-device pairing plus a foldable 220 g over-ear is a combination the Pulsar simply can't match. Check the current price on Amazon before deciding, since value is the one thing neither spec sheet can tell you.
FAQ
Yes — dual-device connectivity is listed as a core feature, and it runs Bluetooth 6.0 with A2DP, AVRCP, HFP and HSP support. That means you can stay paired to a laptop and a phone and switch between calls and music without repairing.
CCA states over 5 hours of playtime per charge and up to 36 hours total with the charging case, with a 30-minute Type-C charge giving hours of playback. The SENECESLI sheet lists a 200 mAh battery but no hour rating, so the Pulsar is the more transparent of the two here.
That comes down to price, which changes constantly — check the current price on Amazon for both. On features alone, the Pulsar gives you documented driver, microphone and battery specs, while the SENECESLI gives you dual-device pairing, a foldable over-ear build and a 90-day warranty.
