If you want a compact in-ear headset for calls and study, choose Plantronics Voyager 5200; if you need over-ear headphones with noise cancellation and long listening time, choose Philips H6509. For study, I’d pick the Philips for focused listening and flexible, all-day use, while the Voyager is the more specialized option for voice calls.
• Plantronics Voyager 5200: Its compact in-ear design, call-oriented controls, and moisture resistance suit hands-free conversations. Its seven-hour battery life and single-ear headset format are less suited to long stretches of music or immersive study listening.
• Philips H6509: Over-ear cushions, active noise cancellation, ambient mode, and up to 70 hours of battery life make it the more versatile listening choice. It is an adult over-ear headphone, not a compact call headset.
• Choose the Voyager 5200 if you mainly need a wireless headset for calls and want a small in-ear design.
• Choose the Philips H6509 if you want noise-canceling headphones for study, music, or other extended listening.
The Voyager 5200 is a Bluetooth in-ear headset built around a different priority from conventional headphones: staying connected for calls. It has push-button volume control, smart sensors, a dynamic mute alert, and a listed Bluetooth range of 30 meters. Moisture resistance is another practical feature for someone who may wear it while moving through a busy day.
Its seven-hour average battery life and 90-minute charge time are useful figures to weigh if you expect to use it for calls throughout the day. The product also comes with a car charger bundle, which may appeal to someone who regularly travels by car. These details make it a plausible choice for adults who need hands-free communication more than a large, enveloping sound experience.

Philips H6509: Who It's For
The Philips H6509 is an over-ear Bluetooth headphone with active noise cancellation and an ambient mode. That combination gives it two distinct approaches to the environment: reduce external noise when you want to concentrate, or let more of your surroundings through when you need awareness or conversation. For someone looking for headphones for study, that flexibility is more directly useful than a call-focused headset design.
Philips lists up to 70 hours of playtime, or up to 45 hours with ANC, along with fast charging that can provide three extra hours of use after five minutes of charging. It also supports connecting to two devices at once, and it includes a cable connection for continued use when the battery runs out. Memory foam cushions and a foldable design point toward longer listening sessions and easier carrying.
The trade-off is size and purpose. These are adult over-ear headphones, not a small in-ear option for someone who wants a discreet headset mainly for calls. If your priorities are compactness and voice communication, the Voyager 5200 is the more focused tool. If you want one pair for studying, music, and switching between devices, the H6509 offers more relevant features.
• Best for study listening → Philips H6509. Over-ear cushions and active noise cancellation are a more natural fit for settling in with reading, lectures, or other audio.
• Best for hands-free calls → Plantronics Voyager 5200. It is an in-ear Bluetooth headset with push-button volume control, smart sensors, and a dynamic mute alert.
• Best for a long gap between charges → Philips H6509. Its listed battery life reaches up to 70 hours without ANC and up to 45 hours with ANC; the Voyager is listed at seven hours.
• Best for hearing more of your surroundings when needed → Philips H6509. Its ambient mode is intended to let surrounding sound through, unlike a listening setup focused only on reducing noise.
• Best for a compact in-ear format → Plantronics Voyager 5200. It is the one to consider if over-ear headphones feel like the wrong form factor.
• Best for switching between two connected devices → Philips H6509. It supports simultaneous connection to two devices.
• Best for moisture resistance → Plantronics Voyager 5200. That listed feature gives it an edge for someone who wants a headset suited to varied day-to-day conditions.
• Best for wired listening as a fallback → Philips H6509. It includes an audio cable connection for use when the battery runs out.
“Open ear earbuds for study” may sound like a useful search, but neither product is described as open-ear earbuds. The Voyager is an in-ear headset, while the Philips is an over-ear headphone with active noise cancellation and ambient mode. If you specifically want an open-ear design, these two do not match that description.
Parents looking for the “best kids headphones for study” should also note that both products are described for adults. The Philips has over-ear cushions and noise cancellation that may suit focused listening, but the available details do not identify either model as a kids’ product. I would not assume a child fit from these specifications alone.
My Verdict
In my opinion, I’d choose the Philips H6509 for study because its over-ear design, ANC, ambient mode, and much longer listed battery life suit extended listening better. It also offers a cable fallback and simultaneous connection to two devices.
I’d choose the Voyager 5200 instead if hands-free calls, a compact in-ear format, and moisture resistance matter more than listening comfort or long sessions. For a study-first purchase, Philips is my clear pick.
The Philips H6509 is the more study-oriented choice based on its over-ear design, active noise cancellation, ambient mode, and listed battery life. The Voyager 5200 is primarily a compact in-ear headset with call-focused features.
The Philips H6509 is listed for up to 70 hours of playtime, or up to 45 hours with ANC. The Plantronics Voyager 5200 is listed with an average battery life of seven hours.
Is the Voyager 5200 better for calls than the Philips H6509?
That depends on which features you’ll use. The Voyager prioritizes a compact in-ear form and call controls, while the Philips adds ANC, ambient mode, long battery life, multipoint connectivity, and a cable option. Check the current price on Amazon before deciding, then compare it with the features you actually need.
