How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want over-ear active noise cancellation with marathon battery life and a wired fallback, choose Srhythm NC25; if you need tiny in-ear buds built for small ears, sweat, and workouts, choose Back Bay Audio Mini.
• Srhythm NC25 — biggest strength: Active Noise Cancellation with dual 40 mm drivers, 50+ hours of playtime, and a 3.5 mm wired mode when the battery runs dry.
• Srhythm NC25 — biggest trade-off: It's a full over-ear headphone at 190 g, so it's bulkier than buds and needs a bag or a case to carry around.
• Back Bay Audio Mini — biggest strength: Six ear-tip sizes in a tiny metal case, IPX7 sweat and water resistance, and a tap-to-boost bass mode.
• Back Bay Audio Mini — biggest trade-off: No active noise cancellation — it relies on sound isolation from the ear tips — and there's no wired jack at all.
• Who each pick is for: Srhythm NC25 suits commuters, flyers, and desk workers who want silence and long sessions. Back Bay Audio Mini suits runners, gym-goers, and anyone whose ears have never fit "one size fits most" buds.
The NC25 is a classic over-ear ANC headphone, and the spec sheet reads like one. Dual 40 mm dynamic drivers, 360° omnidirectional active noise cancellation, 32 ohm impedance, 99 dB sensitivity, and a 20 Hz–20 kHz frequency response. The ANC works in both wireless and wired mode, which is the detail I care about most here — plenty of budget ANC headphones quietly disable noise cancelling the moment you plug in a cable. This one doesn't.
Battery is the headline number: a 1000 mAh cell rated for 50 hours of playtime and a 2.5-hour charge. That's roughly a week of commuting on a single charge, and if you do run it flat, the included 3.5 mm cable (100 cm) keeps the music going. Bluetooth 5.3 with a 15-meter range and multi-point connection means you can stay paired to a laptop and a phone at once and switch between them without repairing.
For gaming and video, there's a low-latency game mode you trigger with a triple-press of the multi-function button — the listed audio latency is 50 ms. Watching TV or taking video calls, that's the difference between audio that feels attached to the picture and audio that feels slightly behind it.
Who should buy it: frequent flyers, train and bus commuters, open-office workers, and anyone who wants one pair for long listening sessions at a desk. The 100° inward rotation and 120° folding ear cups plus the 0.4 lb (190 g) weight make it genuinely packable for travel, and the protein ear pads are built for long wear. The replaceable ear pads are a nice touch for longevity.
Who should skip it: if you hate anything on your head, or you want buds that vanish into a pocket. This is a circumaural headphone — it sits around your ears, and no amount of folding changes that.
The Back Bay Audio Mini (model name Back Bay Tempo 30) attacks a different problem entirely: fit. Six ear-tip sizes, from extra-small to XXL, in a small in-ear bud. If you've ever had buds slowly work their way loose, or felt pressure and ache after twenty minutes, that range of tip sizes is the whole point of this product.
The rest of the package is built for movement. IPX7 water resistance means sweat and rain are fine — though the brand is explicit that these are not swimming earbuds. An 8 mm dynamic driver with 16 ohm impedance, 110 dB sensitivity, and a 20 kHz frequency response keeps them easy to drive from a phone. There's a Bass Boost mode you toggle with a tap on the right bud, and a movie mode for lag-free watching; the listed audio latency is 40 ms, slightly lower than the NC25's.
Battery is 8 hours in the buds plus 24 more in the aluminum charging case for 32 hours total, recharged over USB-C in about 2 hours. The case itself is small — roughly 2.43 x 1.29 x 1 inches and 36 g — and the buds weigh 45 g combined, so this disappears into a pocket. Bluetooth 5 connects to any Bluetooth device, with a 30-foot range, and two microphones handle calls with environmental noise cancellation.
Who should buy it: runners, gym regulars, cyclists, and small-eared listeners who've given up on one-size buds. Also good if you want bass you can feel without dragging a headphone case around.
Who should skip it: if you fly a lot or work somewhere loud and want silence on demand. Sound isolation from a good tip seal is not the same as active noise cancellation, and there's no 3.5 mm jack as a backup.
• Best for noise cancellation → Srhythm NC25. Active ANC with omnidirectional coverage, working in wired and wireless modes.
• Best for battery life → Srhythm NC25. 50 hours versus 32 hours total on the Mini (8 in the buds plus 24 in the case).
• Best for workouts and sweat → Back Bay Audio Mini. IPX7 water resistance and a secure in-ear fit; the NC25 has no water-resistance rating listed.
• Best for small ears → Back Bay Audio Mini. Six tip sizes from extra-small to XXL is the entire design premise.
• Best for long desk or travel sessions → Srhythm NC25. Over-ear pads, a multi-level adjustable headband, and folding ear cups.
• Best for gaming and video → a near-tie, leaning Back Bay Audio Mini. 40 ms latency versus 50 ms, but the NC25 adds a dedicated game mode and works wired if you want zero wireless delay.
• Best for portability → Back Bay Audio Mini. A 36 g metal case in your pocket beats a folded 190 g headphone in a bag.
• Best for wired backup → Srhythm NC25. It's the only one of the two with a 3.5 mm jack.
In my opinion, the Srhythm NC25 is the better buy for most people, because active noise cancellation plus 50 hours of battery plus a wired fallback covers more situations than any single feature on the Mini. That said, I'd steer you to the Back Bay Audio Mini without hesitation if your ears have never gotten along with buds, or if your listening happens while you're moving and sweating. The honest split is this: one is a quiet-room headphone, the other is a go-anywhere earbud. Pick the problem you actually have. Whichever you land on, check the current price on Amazon before deciding, since that's the one thing specs can't tell you.
Yes. The NC25 has active noise cancellation that works in both wired and wireless mode. The Mini relies on sound isolation from the ear-tip seal, which helps with droning background noise but won't match powered ANC on a plane or train.
They're designed for it. IPX7 water resistance covers sweat and rain, and six ear-tip sizes help you find a seal that stays put. Just note the brand says they are not for swimming.
The NC25, at 50 hours on a single 2.5-hour charge. The Mini gives you 8 hours per charge in the buds plus 24 hours in the case, for 32 hours total, recharging in about 2 hours via USB-C.
Yes. Bluetooth 5 connects to any Bluetooth-enabled phone or computer, and the brand lists iPhone and iPad compatibility. The NC25 does the same with Bluetooth 5.3 and adds multi-point pairing for two devices at once.
