How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a work-from-home headset you can wear for a full shift and pair to your laptop and phone at the same time, choose Kinnect Now Edge; if you need pocket-sized earbuds for commuting, workouts and everyday listening, choose Sony WF-C510. Both support Bluetooth multipoint, but they solve completely different problems.
• Kinnect Now Edge — biggest strength: an on-ear design with a patented Featherlite headband, 3.6 oz of weight, 30+ hours of talk time and multipoint over Bluetooth 5.0.
• Kinnect Now Edge — biggest trade-off: it is a headset, not earbuds. It sits on your ears, and it is built around calls and long wear rather than portable music listening.
• Sony WF-C510 — biggest strength: truly wireless in-ear buds with 11 hours per charge (22 with the case), 5-minute quick charging, IPX4 water resistance and multipoint over Bluetooth 5.3.
• Sony WF-C510 — biggest trade-off: battery life per charge is far shorter than the Edge, and there is no active noise cancellation — the spec sheet lists noise control as "None."
• Pick Kinnect Now Edge if you live on calls all day and want one headset for your computer and your phone.
• Pick Sony WF-C510 if you want compact buds for music, movement and life outside the desk.
The Kinnect Now Edge is a Bluetooth 5.0 on-ear headset with a microphone, and everything about it points at the workday. The headline feature is the Featherlite headband, which the specs say distributes weight evenly to cut ear fatigue during long sessions. At 3.6 oz with faux leather and plastic construction, this is a headset designed to sit on your head for hours without you thinking about it. If you have ever pulled off a cheap headset after a three-hour block of meetings, you know why that matters.
Battery is the second pillar. Kinnect Now rates it at 30+ hours of talk time and roughly a one-hour charge time. That is a genuinely full workweek of calls for many people, with no mid-day top-ups. The spec sheet also claims 93% background noise filtering and passive noise cancellation, plus a 40-meter Bluetooth range — a big number that tells you the radio is meant to hold up when you walk away from your desk mid-call. Multipoint lets you stay connected to two devices at once, so a call coming in on your phone can pull you off your laptop without re-pairing anything.
Sony WF-C510: Who It's For
The Sony WF-C510 is a pair of truly wireless in-ear buds, and Sony's spec sheet reads like a checklist for daily life rather than the office. You get up to 11 hours of playback per charge and up to 22 hours with the case, plus quick charging that gives you roughly an hour of playback from a 5-minute top-up. For a commute, a lunch break and a walk home, that rhythm works well — the case lives in your pocket, and the buds themselves are light and compact for an all-day fit.
Multipoint is here too, on Bluetooth 5.3. Sony describes it the way you would actually use it: pair two devices, and when a call comes in, the buds connect to the right one automatically. Around that, the WF-C510 adds features the Edge simply does not have — Ambient Sound Mode to keep you aware of traffic or a colleague walking up, Voice Focus to pull human voices out of the background, an IPX4 water resistance rating so sweat and splashes are not a problem, and DSEE processing to lift compressed music files. There is also EQ control and a touch interface through Sony's companion app.
The trade-offs are equally clear. There is no noise control at all per the spec sheet — you get ambient awareness, not cancellation — and the Bluetooth range is listed at 10 meters versus the Edge's 40. In-ear fit is personal; some people love the seal, others find buds tiring over a long day. Who should buy it: commuters, gym-goers, students and anyone who wants one small pair of buds for music, calls and movement. Who should skip it: anyone who needs a headset for eight hours of back-to-back calls, or who wants maximum time between charges.
Side-by-Side: Which Should You Choose?
• Best for all-day talk time → Kinnect Now Edge. 30+ hours of talk time versus 11 hours per charge on the Sony buds.
• Best for portability → Sony WF-C510. Truly wireless buds with a small cylindrical case, versus an on-ear headset you wear or carry.
• Best for workouts and weather → Sony WF-C510. IPX4 water resistance; the Edge has no water resistance rating in its specs.
• Best for staying aware of your surroundings → Sony WF-C510. Ambient Sound Mode and Voice Focus have no equivalent on the Edge.
• Best for range away from your device → Kinnect Now Edge. 40 meters of Bluetooth range versus 10 meters.
• Best Bluetooth version → Sony WF-C510. Bluetooth 5.3 versus 5.0 — newer, though both handle multipoint.
• Best for music-first listening → Sony WF-C510. DSEE upscaling, EQ via app and a 6 mm dynamic driver tuned for streaming.
If I had to buy one, I would buy the Kinnect Now Edge — but only because my day is mostly calls. Thirty-plus hours of talk time, a headband built to fight ear fatigue, and multipoint across my laptop and phone is the exact combination I want at a desk. If your day looks more like music on the train, a run at lunch and podcasts on the way home, I would point you to the Sony WF-C510 instead — the IPX4 rating, ambient mode and pocketable case make it the better everyday companion. In my opinion, neither is "better" overall; they are built for two different lives. Check the current price on Amazon before you decide, since that is the one variable that can flip this call.
what is multipoint bluetooth headphones
Multipoint Bluetooth is a feature that lets one pair of headphones stay connected to two devices at the same time — for example a laptop and a phone. When a call comes in, the headphones switch to the ringing device automatically instead of you re-pairing anything. Both the Kinnect Now Edge and the Sony WF-C510 support it.
can bluetooth headphones connect to multiple devices
Yes, if they support multipoint — and both of these do. The Kinnect Now Edge pairs with two devices over Bluetooth 5.0, and the Sony WF-C510 pairs with two over Bluetooth 5.3. Without multipoint, you would have to disconnect from one device before connecting to another.
which headphones have bluetooth multipoint
In this comparison, both do. The Kinnect Now Edge lists multipoint connection (2) alongside Bluetooth 5.0, and the Sony WF-C510 lists multipoint connection on Bluetooth 5.3. If multipoint is your must-have feature, both options clear that bar — the real difference is the form factor and battery life.
is the Sony WF-C510 good for work calls
It handles hands-free calling with a built-in mic and wind noise reduction, and multipoint keeps it tied to your phone and computer. But it has no active noise cancellation per its specs, and 11 hours per charge is far less than the Edge's 30+ hours of talk time. For occasional calls, fine; for a full day of meetings, I would take the Edge.
