If you want long battery life and adaptive noise cancellation in over-ear headphones for small ears, choose Sennhesier Sennheiser ACCENTUM Plus; if you need longer stated playtime and distinct ANC, transparency, and standard modes, choose Monster Persona 6th. The ACCENTUM Plus is the more adaptable pick for changing environments, while the Persona offers more listening modes and a longer listed battery life.
• ACCENTUM Plus strength: Adaptive Hybrid ANC responds to changing noise levels; its trade-off is a stated battery life of up to 50 hours, shorter than the Persona’s.
• Monster Persona 6th strength: Up to 60 hours of playtime and three listening modes; its trade-off is that the listed connectivity is wireless Bluetooth, with no headphone jack.
• Both are over-ear wireless headphones with active noise cancellation, but neither product sheet gives dimensions or earcup measurements to confirm fit for small ears.
• Choose ACCENTUM Plus for adaptive noise control, a 3.5 mm jack, and a quick-charge feature that provides five hours of playback after about 10 minutes.
• Choose Persona 6th if you want a stated 60-hour battery life, Bluetooth 6.0, and a transparency mode for hearing more of your surroundings.
The ACCENTUM Plus is a sensible fit for someone who wants over-ear headphones for travel, school, or noisy work settings and values noise cancellation that adjusts to changing surroundings. Its Adaptive Hybrid ANC is described as responding dynamically to noise levels, which makes it a useful feature to consider if your day moves between quieter rooms and crowded places. The product also offers voice customisation to create a listening profile matched to your preference.
Battery life is a clear strength: the stated maximum is 50 hours, and about 10 minutes of charging is said to provide five hours of playback. That quick-charge detail matters when you have a short window to top up before heading out. The listed 3.5 mm jack also gives it a wired connection option, alongside Bluetooth 5 and a listed range of 10 metres. Its audio frequency range is 10 Hz to 22,000 Hz, and the headphones weigh 227 g.

For small ears, the key question is fit, not the battery figure. ACCENTUM Plus is described as over-ear, but no earcup dimensions or small-ear fit details are provided. I would not assume the cups will suit every head or ear shape based on the product information alone. Skip it if a confirmed small-ear fit is essential before you buy, or if you specifically want a transparency mode listed as a separate listening option.
Monster Persona 6th: Who It's For
The Monster Persona 6th is aimed at listeners who want a long stated runtime and straightforward choices between different listening situations. It lists up to 60 hours of playtime, with a quick-charge feature said to provide five hours of playback after a 10-minute charge. That makes its battery specification appealing for long stretches between charging opportunities, such as travel days or a busy workweek.
Its three modes are ANC, transparency, and standard. ANC is for reducing outside noise, while transparency is intended to help you remain more aware of your surroundings; standard mode offers a balanced option for everyday listening. The headphones use Bluetooth 6.0 and have a folding design, adjustable headband, and memory-foam earcups. Those details may appeal if you want wireless listening with a design intended to pack away more easily. The product information does not list a headphone jack.
The Persona is also described as over-ear, but the sheet gives no earcup dimensions or small-ear fit measurements. The adjustable headband and cushioned cups describe design features, not a guarantee that the fit will work for smaller ears. Skip it if you need a wired 3.5 mm connection, or if you want documented dimensions to judge small-ear fit before choosing.
• Best for longer stated battery life → Monster Persona 6th. It lists up to 60 hours, compared with up to 50 hours for ACCENTUM Plus.
• Best for adaptive noise cancellation → ACCENTUM Plus. Its Adaptive Hybrid ANC is described as adjusting to changing noise levels.
• Best for a dedicated transparency mode → Monster Persona 6th. Its listed modes include ANC, transparency, and standard listening.
• Best for a wired option → ACCENTUM Plus. It includes a 3.5 mm headphone jack; the Persona information says there is no jack.
• Best for Bluetooth version by the listed specification → Monster Persona 6th. It specifies Bluetooth 6.0, while ACCENTUM Plus lists Bluetooth 5.
• Best for voice-profile personalisation → ACCENTUM Plus. Its voice customisation function creates a profile based on listening preference.
• Best for a folding design → Monster Persona 6th. Folding is explicitly listed, though the product information does not provide folded dimensions.
• Best for small ears based on confirmed fit data → Neither. Both are described as over-ear, and neither sheet supplies earcup measurements or a small-ear fit claim.
I would choose the ACCENTUM Plus for its adaptive ANC, 3.5 mm jack, and voice customisation, especially if I wanted a flexible over-ear option for commuting and work. Its 50-hour stated battery life and quick-charge feature also make it a strong everyday candidate. For small ears, though, neither product provides enough fit information to promise a comfortable match; I would check the fit details carefully before deciding.
The biggest practical difference is how each model describes noise control. ACCENTUM Plus emphasizes adaptive ANC that responds as surrounding noise changes. Persona 6th makes its options more explicit, listing ANC, transparency, and standard modes. If you often want to hear more of your surroundings without removing your headphones, that transparency mode is a specific feature in the Monster sheet. If your priority is noise cancellation that adjusts to a changing environment, the Sennheiser description is more directly relevant.
The battery figures are useful, but they do not settle every buying question. Persona 6th lists 60 hours, while ACCENTUM Plus lists 50 hours; both also claim five hours of playback from a 10-minute charge. These are the stated specifications, not a promise of identical results in every listening situation. The sheets do not specify how particular settings affect runtime, so I would treat the figures as a comparison point rather than a precise prediction for every use.
Fit deserves extra attention if you are searching for the best open ear headphones for small ears or the best sweat resistant earbuds for small ears. These are over-ear headphones, not open-ear headphones or earbuds, and neither sheet provides sweat-resistance information. The phrase ipx7 waterproof on ear headphones for small ears also does not describe a feature listed for either model: neither product sheet gives an IPX7 rating or waterproof claim. If those qualities are essential, these two options do not have the supporting specifications to confirm them.
Finally, consider how you connect and personalise your listening. ACCENTUM Plus lists a 3.5 mm jack and voice customisation, while Persona 6th lists Bluetooth 6.0 and a folding design. The supplied information does not establish which headphone sounds better in practice, nor does it provide dimensions that would resolve small-ear comfort. Choose based on the features that matter most, and check current product details for any fit or protection information you need before buying.
