How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a featherweight, ultra-discreet pair of earbuds for workouts, small ears, and all-day comfort on a tight budget, choose TOZO A2; if you need serious active noise cancellation, marathon battery life, and over-ear immersion for commuting, flying, or long work sessions, choose Cubitt Tracking Technologies Power Headphones.
• TOZO A2 — biggest strength: At just 3.7 g per earbud with a polished, rounded in-ear shape, it's about as light and unobtrusive as earbuds get, and Bluetooth 5.3 keeps the connection stable.
• TOZO A2 — biggest trade-off: No active noise cancellation (only sound isolation), 5 hours per charge, and a 20-hour total with the case — fine for a day, not for a week.
• Cubitt Power Headphones — biggest strength: Hybrid ANC with three modes plus up to 60 hours of battery life, wrapped in a foldable over-ear design with a stainless steel build.
• Cubitt Power Headphones — biggest trade-off: It's an over-ear headphone, so it's bulkier, and it's wireless-only with no headphone jack.
• Pick TOZO A2 if portability, a barely-there fit, and true wireless freedom matter most.
• Pick Cubitt Power Headphones if noise cancellation and battery endurance are your priorities.
The TOZO A2 is built around one idea: get out of the way. A single earbud weighs 3.7 grams, and TOZO says the in-ear surface and angle were refined to sit flush so the buds don't protrude. In practice, that makes them a natural fit for the gym, running, or any activity where you don't want something tugging at your ears.
Sound comes from a 6 mm dynamic driver with a 20 Hz–20 kHz frequency range, 32 ohm impedance, and 113 dB sensitivity. That's a modest driver, but the tuning aims for punchy bass and lively treble, and TOZO cites latency as low as 60 ms — good news for watching video without noticeable lip-sync lag. Calls run through a built-in mic with noise reduction; the spec sheet lists HSP, HFP, A2DP, and AVRCP support and stereo in-call audio.
Battery is where you need to be realistic. You get about 5 hours per charge and up to 20 hours total with the three extra charges in the case. The case itself recharges in about an hour over USB-C. Touch controls handle volume, track skipping, play/pause, calls, and voice assistant.
Who should buy it: anyone with smaller ears who finds most buds uncomfortable, people who want a light, discreet set for workouts, and shoppers who want a simple true-wireless pair without paying for features they won't use.
Who should skip it: frequent flyers, open-office workers, and anyone who wants to silence a noisy room. There's no ANC here — only passive sound isolation — and 20 hours total means you'll be reaching for the charger regularly.
The Cubitt Power Headphones take the opposite approach: block the world out and keep going for days. They're over-ear headphones with hybrid active noise cancellation and three selectable modes — ANC On, ANC Off, and Transparency — so you can fully mute your surroundings, kill the processing to save battery, or let ambient sound in when you need to hear a gate announcement or a coworker.
Battery life is the headline: up to 60 hours of playtime on a single charge. That's the kind of number that means you can pack them for a week-long trip and realistically not think about the charger. When you do need to top up, fast USB-C charging cuts down the downtime.
The build uses stainless steel in the enclosure, and the design folds for travel. That combination matters if you're tossing them in a bag or a carry-on — a foldable over-ear is far less awkward to pack than a rigid one. Bluetooth 5.4 handles pairing with iOS, Android, laptops, and other wireless sources; there's no headphone jack, so it's wireless-only by design.
For calls, Cubitt uses four microphones with noise-reduction processing, which should help you sound clear in busy or windy environments. The audio is driven by a dynamic driver tuned for powerful bass and crisp treble. Controls are push-button rather than touch — a small but real preference point, since buttons are easier to operate with gloves or when you're not looking. The headphones are listed for ages 12 and up.
Who should buy it: commuters, remote workers, and travelers who want ANC and don't want to think about charging. Also a good fit if you prefer over-ear comfort and physical buttons over touch controls.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → Cubitt Power Headphones. Hybrid ANC with three modes versus passive isolation only on the TOZO A2.
• Best for battery life → Cubitt Power Headphones. Up to 60 hours on one charge versus 20 hours total for the TOZO A2.
• Best for workouts and small ears → TOZO A2. 3.7 g per bud, flush in-ear fit, and a design explicitly aimed at sports and gym use.
• Best for travel packing → Cubitt Power Headphones. The foldable over-ear design packs down; the TOZO case is compact but the headphones themselves fold.
• Best for calls in noisy places → Cubitt Power Headphones. Four microphones with noise reduction versus a single built-in mic on the TOZO A2.
• Best for touch controls → TOZO A2. Touch control for volume, tracks, calls, and voice assistant versus push buttons on the Cubitt.
• Best for discretion → TOZO A2. An in-ear bud that doesn't protrude is far less noticeable than an over-ear headphone.
• Best for low-latency video → TOZO A2. TOZO lists 60 ms latency, which matters for gaming and streaming.
If I had to pick one, I'd buy the Cubitt Tracking Technologies Power Headphones. In my opinion, 60 hours of battery life and real hybrid ANC cover more of the situations where headphones actually earn their keep — flights, commutes, noisy offices, and long trips where charging is a hassle. The foldable stainless-steel build and four-mic call setup round it out nicely.
That said, I'd steer you to the TOZO A2 without hesitation if your priority is a barely-there fit for running, lifting, or wearing for hours without noticing. It's the better pick for small ears and anyone who hates bulky gear. Two different jobs, two different answers — and that's the honest call.

The TOZO A2. At 3.7 g per earbud with a flush, rounded in-ear fit, it's designed for sports and gym use. The Cubitt is an over-ear headphone, which is bulkier and more prone to shifting during intense movement.
