• Sennheiser Accentum — biggest strength: up to 50 hours of battery life with Bluetooth and ANC running, plus Hybrid Noise Cancellation and a 5-band EQ you control from an app.
• Sennheiser Accentum — biggest trade-off: it's adult-focused and wireless-only. No 3.5 mm jack, so there's no cable option when the battery eventually runs down.
• Puro Sound Labs BT2200 — biggest strength: volume-limiting technology capped at 85 dB, designed specifically to protect young ears, with a 3.5 mm cable included for unlimited wired listening.
• Puro Sound Labs BT2200 — biggest trade-off: no noise cancelling and a 20-hour battery — a fraction of the Sennheiser's runtime.
• Who each is for: the Accentum is for an adult who wants one set of over-ears for commuting, work and travel. The BT2200 Plus is for a parent buying for a kid.
The Accentum is what happens when a headphone brand decides battery life is the headline feature. Sennheiser quotes up to 50 hours on a single charge with Bluetooth and Hybrid ANC both switched on. Read that again, because it's the number that reframes everything else on this page: two full work weeks of commuting on one charge, or a long-haul trip there and back without ever hunting for a USB-C cable. And when you do need to charge, it's USB-C with fast charging, and a full charge takes about 3 hours.
Around that battery sits a genuinely full-featured package. Hybrid ANC handles the low rumble of trains, planes and open-plan offices. Clear Mode lets you hear what's going on around you with a single touch instead of pulling the headphones off. And the sound isn't locked in place — predefined modes cover Bass Boost and Podcast, and there's a built-in 5-band equalizer, all driven from an app. That's a meaningful difference for anyone who listens to a mix of music, spoken word and video calls in a day and wants each to sound right.
The physical design is aimed squarely at long sessions. It's over-ear, weighs 222 g, and uses a soft-touch silicone headband with deep ear pads. Drivers are 37 mm dynamic, with a 20 Hz–20,000 Hz range, 60 ohm impedance, 106 dB sensitivity, and Bluetooth 5.2 with roughly 10 m of range. A faux leather carrying case is included, which tells you Sennheiser expects this to travel.
Who should buy it: an adult who wants one do-everything wireless headphone with class-leading stamina, real ANC, and sound they can shape themselves. Who should skip it: anyone shopping for a child, and anyone who wants a wired option — there's no headphone jack here at all. If you're the kind of person who keeps a cable in your bag as a safety net, this isn't that headphone.
The BT2200 Plus is built around one non-negotiable idea: a child's ears shouldn't be able to receive more than 85 dB. That's the volume-limiting technology at the core of the product, and it's the reason this headphone exists. Everything else — the Puro Balanced Response Curve, the interchangeable ear cups, the color options — is arranged around protecting hearing while still sounding like something a kid actually wants to wear.
That last part matters more than parents expect. A headphone that sounds thin or muffled gets abandoned, and an abandoned headphone protects nobody. Puro's answer is its Balanced Response Curve, which aims for clear vocals and deep bass within the safe 85 dB ceiling. So the limit is the ceiling, not the whole experience. The drivers are dynamic, with a 20 Hz–20,000 Hz frequency range, so the fundamentals are in line with what you'd expect from an over-ear design.
Flexibility is the other half of the story. Battery life is up to 20 hours of playback with 200 hours of standby — genuinely fine for a school week, though nowhere near the Sennheiser's 50. More importantly, when the battery does run low, or when a teacher or flight-mode rule says no Bluetooth, you plug in the included 3.5 mm cable and keep going indefinitely. That wired fallback is a real advantage for kids, and it's the exact feature the Accentum lacks. The ear cups are also interchangeable between on-ear and over-ear, so you can tune the fit as your child grows or simply prefers one feel over the other, and the cushions are vegan leather with a comfy headband.
Who should buy it: a parent who wants volume-limited headphones for a child, with a wired option for school, travel and long trips. Who should skip it: an adult who wants noise cancelling, app-based EQ or marathon battery life — the BT2200 has none of those. It's also worth noting it's labeled for kids, so the fit and tuning are aimed at younger heads. Puro backs it with a one-year coverage and a 30-day return guarantee.
Side-by-Side: Which Should You Choose?
• Best for battery life → Sennheiser Accentum. Up to 50 hours with Bluetooth and ANC on versus up to 20 hours on the BT2200.
• Best for noise cancelling → Sennheiser Accentum. Hybrid ANC and Clear Mode; the BT2200 has no noise control at all.
• Best for sound customization → Sennheiser Accentum. Predefined modes, Bass Boost, Podcast mode and a 5-band EQ via app.
• Best for wired listening → Puro Sound Labs BT2200. A 3.5 mm jack and included cable; the Accentum has no jack.
• Best for travel and commuting → Sennheiser Accentum. ANC, a carrying case and 50 hours of runtime.
• Best for kids, school and shared devices → Puro Sound Labs BT2200. Volume-limited, kid-labeled, with interchangeable ear cups.
• Best for a growing child's fit → Puro Sound Labs BT2200. Switch between on-ear and over-ear cushions as needed.
For myself, I'd buy the Sennheiser Accentum. In my opinion, the combination of up to 50 hours of battery with ANC running, Hybrid Noise Cancellation, Clear Mode and app-based EQ makes it the more capable headphone by a wide margin — and the lack of a headphone jack is a trade-off I'd accept for that runtime.
But I wouldn't frame this as one product beating the other, because they're solving different problems. If I were buying for a child, I'd pick the Puro Sound Labs BT2200 without hesitation: the 85 dB limit, the wired fallback and the interchangeable ear cups are exactly what a kid's headphone should have. Buy the Accentum for yourself, the BT2200 for your kid.
Not universally — they're aimed at different users. The Accentum has far longer battery life, active noise cancelling and app-based EQ, while the BT2200 is built around an 85 dB volume limit for children's hearing. For an adult, I'd lean Accentum; for a child, BT2200.
They'll work, but they're designed and labeled for kids, with a volume ceiling that many adults will find restrictive and no noise cancelling. If you're an adult wanting ANC and a customizable sound profile, the Sennheiser Accentum fits that brief better.
No. The Accentum is wireless-only via Bluetooth 5.2 and has no headphone jack, so it depends entirely on its battery. If you want a cable fallback, the Puro Sound Labs BT2200 includes a 3.5 mm audio cable for unlimited wired listening.
