If you want comfortable over-ear listening with long battery life and active noise cancellation, choose Edifier W830NB; if you need compact earbuds for small ears and exercise outside the water, choose Back Bay Audio Mini. For swimming, choose neither: Back Bay specifically says its earbuds are not designed for swimming, and the Edifier specs do not establish that they are water-resistant.
Edifier W830NB vs Back Bay Audio Mini at a Glance
• Edifier W830NB: Over-ear design, hybrid active noise cancellation, and up to 94 hours of playback with ANC off; its larger headphone format is less compact than earbuds.
• Back Bay Audio Mini: Small-profile earbuds with six ear-tip sizes, an IPX7 water-resistance rating, and up to 32 hours including the case; the manufacturer says they are not for swimming.
• Edifier W830NB is for: Listeners who want noise-control options, long playback, and a foldable over-ear headphone.
• Back Bay Audio Mini is for: People who want small earbuds for exercise, rain, or everyday use and value multiple tip sizes.
• For swimming: Neither product is supported by the supplied specifications as a suitable choice.
The W830NB is an over-ear Bluetooth headphone built around 40 mm dynamic drivers. Its main strengths are a broad set of listening features and long stated battery life: up to 94 hours with ANC off, plus a 15-minute charge said to provide up to 10 hours of use. Those figures make it appealing for long stretches of listening, travel, or days when you would rather not keep checking the battery.
Its hybrid ANC offers High and Medium settings, alongside Wind Reduction and Ambient Sound modes. That flexibility is useful if you want to choose between reducing surrounding noise and letting more of it through. LDAC support, spatial audio, multipoint connection, and DNN call-noise reduction add to the feature set. The headphones also fold, have an adjustable headband and soft earpads, and weigh around 265–267 g according to the supplied information.

Back Bay Audio Mini is a compact in-ear set aimed at people who have trouble getting a comfortable fit from standard earbuds. It includes six ear-tip sizes, from extra-small to XXL, giving buyers more options to find a secure-feeling fit. The earbuds offer an extra-bass mode, and their stated eight hours of playback per charge can be extended by another 24 hours from the case, for up to 32 hours in total.
The IPX7 rating and sweatproof positioning make these more relevant than the Edifier for workouts, rainy walks, and other situations involving sweat or splashes. But there is an important boundary: Back Bay says these earbuds are not for swimming. Water resistance for exercise or rain should not be read as a claim that they are suitable for wearing in a pool.
I’d look at the Mini if you want small earbuds with several tip sizes and a charging case, especially for exercise on land. I would skip them if swimming is the main use, or if you want over-ear noise cancellation: the supplied feature information lists sound isolation, not active noise cancellation. Their 32-hour total is also a combined figure that includes the case, rather than one continuous charge.
• Best for extended playback between charges → Edifier W830NB. Its stated maximum is 94 hours with ANC off. The Back Bay set provides up to eight hours per earbud charge, with the case adding 24 hours.
• Best for choosing how much surrounding sound to hear → Edifier W830NB. It has High and Medium ANC, Wind Reduction, and Ambient Sound modes.
• Best for people who need several ear-tip sizes → Back Bay Audio Mini. Six sizes offer more fit options than the over-ear Edifier’s adjustable headband and earpads.
• Best for workouts where sweat or rain is a concern → Back Bay Audio Mini. It is described as sweatproof and rated IPX7, but the manufacturer explicitly excludes swimming.
• Best for folding away in a bag → Edifier W830NB. The headphones fold for portability, though they remain an over-ear design rather than compact buds.
• Best for bass you can switch up → Back Bay Audio Mini. Its extra-bass mode is activated by a button, giving it a specific sound option for workouts or music where you want a stronger bass emphasis.
• Best for spatial audio and LDAC support → Edifier W830NB. Its listed features include both, along with 40 mm dynamic drivers.
• Best for swimming → Neither. Back Bay says the Mini is not designed for swimming, and no water-resistance claim is provided for the Edifier.
The swimming distinction matters more than the general water-related language. An IPX7 rating on the Back Bay product does not override its explicit warning against swimming. And without a stated water-resistance rating for the W830NB, there is no sound basis here to recommend it for pool use either. If you searched for the best true wireless earbuds for swimming, these two products do not meet that brief based on the available product details.
I would choose the Edifier W830NB for everyday listening because its long stated battery life, four noise-control modes, foldable design, and LDAC support make it the more versatile headphone for travel and focused listening. I’d choose Back Bay Audio Mini instead if a small in-ear fit and sweat resistance matter more.
For swimming, though, I recommend neither. Back Bay clearly excludes swimming, and the Edifier information does not establish that it is water-resistant. Neither is a responsible pick among in ear earbuds for swimming or the best wireless earbuds for swimming.
No. They have an IPX7 rating and are described as sweatproof, but Back Bay explicitly says they are not designed for swimming. I would not interpret water resistance as permission to use them in a pool.
I would choose neither product for that use based on the information available.
The Edifier is listed for up to 94 hours of playback with ANC off. Back Bay lists up to 32 hours total, combining eight hours from the earbuds with 24 more hours from the charging case.
Back Bay Audio Mini is the more fitting option to consider: it has six ear-tip sizes and is described as sweatproof and IPX7-rated. That makes it relevant to workouts on land, not swimming.
