• Bowers & Wilkins Limited — biggest strength: 40mm angled dynamic drivers, 24-bit DSP, aptX Adaptive, and six-mic active noise cancellation for serious listening and clear calls.
• Bowers & Wilkins Limited — biggest trade-off: 30 hours of playback, but a 307g over-ear build and a design clearly aimed at adults — not kids.
• Puro Sound Labs BT2200 — biggest strength: Hard 85dB volume cap, Puro Balanced Response Curve, and interchangeable on-ear/over-ear cups built for young ears.
• Puro Sound Labs BT2200 — biggest trade-off: No noise cancellation, only 20 hours of battery, and audio tuned for safety rather than audiophile detail.
• Bowers & Wilkins Limited is for adults who want noise-cancelling over-ear headphones for commuting, work, and critical listening.
• Puro Sound Labs BT2200 is for parents buying headphones for a child who needs safe volume limits for school, travel, or home use.
The Bowers & Wilkins Px7 S2e Limited Edition is a serious over-ear headphone. Each earcup holds a custom 40mm dynamic driver angled toward the ear, paired with 24-bit DSP and Qualcomm aptX Adaptive over Bluetooth 5.3. On paper that combination is about detail and imaging — the kind of tuning that rewards lossless streaming and well-mastered tracks rather than casual podcast listening. The frequency response spans 10Hz to 20kHz, with 8-ohm impedance and 111dB sensitivity, which tells you these are efficient and easy to drive.
Everyday use is clearly the target. Six microphones handle active noise cancellation and call clarity, so they work as well on a noisy train as they do on a Zoom call. The Bowers & Wilkins music app adds direct streaming and voice assistant support, and the physical package includes a 1.2m USB-C to 3.5mm cable, a 1.2m USB-C to USB-C cable, and a protective hard case in red leather. At 307g with plush foam earpads and metal and leather accents, these are built for long sessions — but they're adult-sized and adult-priced in terms of positioning.
Buy Bowers & Wilkins Limited if you want one pair of over-ear headphones that does noise cancellation, wired and wireless listening, and premium sound for music, calls, and travel. Skip it if you're shopping for a child, need a volume cap, or want the lightest possible pair — this is an adult audiophile product, not a safety product.
The Puro Sound Labs BT2200 Plus is a kids' headphone first and an audio product second, and that's the point. Its defining feature is a hard 85dB volume limit — a ceiling chosen to protect young ears during long listening sessions. On top of that sits the Puro Balanced Response Curve, which aims for clear vocals and deep bass within that safe range, using a dynamic driver with a 20Hz–20,000Hz frequency range.
Flexibility is where it earns its keep. The earcups are interchangeable, so a child can run them on-ear or over-ear depending on fit and comfort, and the vegan leather cushions and comfy headband are designed for all-day wear. Battery life is 20 hours for playback with 200 hours of standby, and when the battery runs down — or when Bluetooth isn't wanted — the included 3.5mm cable turns them into a passive wired headphone with unlimited listening. That covers school tablets, in-flight entertainment screens, and older devices without Bluetooth. The colorway is Purple & Teal, and the package includes the cable.
There's no active noise cancellation here, so these won't block out a plane cabin the way an ANC model does. They also top out at 20 hours, and the tuning is deliberately restrained rather than detailed. Buy the BT2200 Plus if you're a parent who wants hearing-safe, comfortable, versatile headphones for a child. Skip it if you're an adult who wants immersive, noise-cancelling sound for yourself.
• Best for hearing safety → Puro Sound Labs BT2200. The 85dB cap is the entire reason this product exists; the Bowers & Wilkins has no such limit.
• Best for sound quality and detail → Bowers & Wilkins Limited. 40mm angled drivers, 24-bit DSP, and aptX Adaptive point to a far more resolving listening experience.
• Best for noise cancellation → Bowers & Wilkins Limited. Six mics with active noise cancellation versus none on the BT2200.
• Best for battery life → Bowers & Wilkins Limited. 30 hours of playback against 20 hours on the Puro.
• Best for kids, school, and travel → Puro Sound Labs BT2200. Kid age range, interchangeable cups, vegan leather cushions, and a volume ceiling made for young ears.
• Best for wired fallback and device compatibility → Puro Sound Labs BT2200. The 3.5mm cable gives unlimited passive listening; the Bowers & Wilkins also goes wired via its included cables, but its wired use is aimed at adult sources.
• Best for calls and voice assistants → Bowers & Wilkins Limited. Six-mic call handling plus app-based voice assistant support.
• Best for durability on the move → Bowers & Wilkins Limited. Metal and leather construction plus a protective hard case beat a lightweight kids' build for travel abuse.
In my opinion, these two products barely compete for the same buyer — they solve different problems. If I were buying for myself, I'd take the Bowers & Wilkins Limited: the angled 40mm drivers, 24-bit DSP, aptX Adaptive, six-mic ANC, and 30-hour battery make it the more capable headphone for music, calls, and commuting, and the included hard case and cables make it a complete package. If I were buying for a child, I'd take the Puro Sound Labs BT2200 without hesitation — the 85dB cap, interchangeable earcups, 20-hour battery, and wired option are exactly what a kid's headphone should be. Match the product to the listener, not the other way around.
FAQ
No. It's designed for adults, with no volume limit and a heavier 307g build. For a child, the Puro Sound Labs BT2200 and its 85dB cap are the safer choice.
No. Its noise control is listed as none, so it won't actively block background noise. The Bowers & Wilkins Limited does offer active noise cancellation with six microphones.
The Bowers & Wilkins Limited offers 30 hours of playback with quick-charge support. The Puro Sound Labs BT2200 offers 20 hours of playback plus 200 hours of standby, and can be used wired when the battery runs out.
