If you want active noise cancellation and a bass-forward in-ear fit for children, choose TPVision Philips TAT3519; if you need an open-ear design with multipoint pairing and all-day awareness, choose Sennheiser ACCENTUM Open. That's the short version, and it's the whole ballgame here.
• TPVision Philips TAT3519 biggest strength: Adaptive Noise Cancellation Pro with an Awareness Mode, plus punchy 10 mm dynamic drivers and a genuinely compact in-ear fit.
• TPVision Philips TAT3519 biggest trade-off: In-ear sealing means you're cut off from the room unless you switch to Awareness Mode — and Adaptive ANC isn't for everyone.
• Sennheiser ACCENTUM Open biggest strength: Open-ear design that keeps you aware of your surroundings, with multipoint pairing and up to 28 hours of playback.
• Sennheiser ACCENTUM Open biggest trade-off: Passive noise cancellation only — the open fit lets sound in by design, so it won't block a noisy commute.
• Pick TPVision Philips TAT3519 if you want noise cancelling, dynamic bass and a snug in-ear seal for children.
• Pick Sennheiser ACCENTUM Open if you want an open, breathable fit and multipoint pairing so two devices stay connected at once.
The TAT3519 is a true-wireless in-ear bud built around a 10 mm dynamic driver and a graphene-coated diaphragm, tuned for what Philips calls a "PHILIPS sound signature." Tap the left earbud and Dynamic Bass kicks in, so low-end stays strong even at lower volumes. For a kid listening to music, watching videos or gaming on a tablet, that's an engaging, energetic sound rather than a flat one.
The headline feature is Noise Canceling Pro. It's adaptive, meaning it suppresses outside sound in real time — including wind — and there's an Awareness Mode when you want the room back. That matters for a child using earbuds at home, in the car or on a bus: you can cut the noise or let it in, depending on the environment. Battery is 8 hours in the buds plus another 16 from the case, for 24 hours total, and 15 minutes of charging buys an extra hour. Bluetooth 5.3 keeps the connection stable, and the buds pair with two devices simultaneously — useful if a phone handles music while a smartwatch pushes notifications.
Comfort is where the TAT3519 earns its keep for younger users. The compact, anti-slip, stick-shaped design sits snugly in the ear, and four sizes of silicone tips are included so you can dial in the fit. IPX4 keeps sweat and splashes from ending the session. Controls are touch-based for playback, volume, calls and noise cancelling, and the Philips Headphones app lets you remap what each earbud does and tailor the sound. The model number is TAT3519GY/00 and it ships with a compact cushioned case.
Who should skip it? Anyone who genuinely needs to hear traffic, a coach or a parent calling from across the house while music plays. The in-ear seal is the point — and the limitation.
The ACCENTUM Open takes the opposite approach. It's an open-ear design, so instead of plugging the canal it rests gently on the ear with a breathable shank. Nothing presses, nothing fatigues, and you stay conscious of your surroundings the entire time. Sennheiser's 11 mm dynamic drivers are tuned for clear, balanced sound intended to blend with your environment rather than fight it.
For a child, that open fit is a real safety and sanity argument. A kid on a bike, walking to school or gaming in a shared room can hear what's going on around them. Parents can call across the room and actually be heard. The trade-off is obvious: this is Passive Noise Cancellation only, so a loud bus or a crowded cafeteria will bleed straight through. If you want quiet, this isn't the tool.
Battery is the other headline. Sennheiser rates up to 28 hours of playback with the compact charging case, charged over USB-C, and a full charge takes about an hour. That covers travel, work, long listening sessions and running without a mid-day top-up. IPX4 splash resistance handles sweat and light rain, so workouts and erratic weather aren't a problem.
Then there's the feature that makes this comparison interesting: multipoint pairing. The ACCENTUM Open connects to two devices at once, so a phone can take a call while a tablet or laptop keeps streaming. There's also smart pause, one-earpiece mode for when you only want one side in, and touch controls, with app control available for deeper settings. It's built for the hybrid worker, the traveler and the gamer who needs audio in one ear and the world in the other.
Who should skip it? Anyone who wants to disappear into the music. The open fit is deliberate, and it's the whole personality of the product.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → TPVision Philips TAT3519. Adaptive ANC with Awareness Mode is the reason to pick it.
• Best for bass and impact → TPVision Philips TAT3519. The 10 mm dynamic driver plus a tap-to-activate Dynamic Bass mode.
• Best for long sessions → Sennheiser ACCENTUM Open. Up to 28 hours of playback and a lightweight, pressure-free fit.
• Best for switching between devices → Sennheiser ACCENTUM Open. Multipoint pairing holds two connections at once.
• Best for a secure in-ear fit during activity → TPVision Philips TAT3519. Anti-slip design, four tip sizes and IPX4.
• Best for a child who games or studies near other people → Sennheiser ACCENTUM Open. They hear the room, and you hear them.
• Best for a child who needs to block out noise → TPVision Philips TAT3519. That's precisely what Adaptive ANC is for.
I'd buy the TPVision Philips TAT3519 if the goal is a focused, noise-cancelling listen for a child — gaming, videos and music with real bass, a snug fit and 24 hours of playtime with the case. I'd buy the Sennheiser ACCENTUM Open if awareness and simplicity matter more: an open, breathable fit, up to 28 hours, and multipoint pairing so two devices stay connected. If you're shopping for children and want the safest everyday default, the ACCENTUM Open is my pick; if you want the more immersive one, the TAT3519 wins.
how to pair multiple headphones
Pairing more than one set of headphones isn't done from the earbuds — each pair connects to the source device separately. With the Sennheiser ACCENTUM Open, multipoint pairing lets those earbuds hold two devices at once, while the TPVision Philips TAT3519 also connects to two devices simultaneously for playback and notifications. To use two different pairs at the same time, you'd generally need a source that supports multiple audio outputs.
how to pair multiple headphones iphone
On an iPhone, you pair one Bluetooth audio device at a time through the Bluetooth settings menu. Multipoint works differently: the earbuds themselves remember two devices. Both the TAT3519 and the ACCENTUM Open support connecting to two devices simultaneously, so you can move between a phone and a tablet without re-pairing each time.
how to pair multiple headphones on ipad
An iPad pairs Bluetooth audio the same way as an iPhone — one device at a time from settings. If you want two sets of earbuds live at once, that depends on the iPad model and app rather than the earbuds. What both products here do offer is two-device memory, so switching between an iPad and a phone is quick rather than a fresh pairing every time.
how to pair multiple bluetooth headphones
Bluetooth audio on most phones and tablets allows a single active connection per pair of earbuds. "Multiple" usually means multipoint: one set of earbuds connected to two sources, which both the Sennheiser ACCENTUM Open and the TPVision Philips TAT3519 support. Running two separate pairs simultaneously requires source-side support that isn't universal.
