If you want lightweight over-ear comfort, longer listed battery life, and adjustable awareness features, choose SONY WH-CH720N; if you need compact in-ear headphones with sweat and splash resistance for running, choose Sudio N3.
For running, I’d lean toward Sudio’s pocketable earbud design, while Sony makes more sense when stronger noise-control flexibility and long listening time matter more.
• SONY WH-CH720N: Its over-ear design, active noise cancellation, adjustable ambient sound, and up to 35 hours of battery life suit long listening sessions. The trade-off for running is its headband format rather than a compact in-ear build.
• Sudio N3: Its in-ear fit, four silicone tip sizes, and sweat and splash resistance make it the more run-oriented choice. Its listed playtime is up to 30 hours, less than Sony’s.
• Pick Sony if you want over-ear headphones with adjustable awareness features and a longer stated battery life.
• Pick Sudio if you want earbuds that are easier to carry and are explicitly described as sweat and splashproof.
The WH-CH720N is an over-ear Bluetooth headphone built around active noise cancellation. Sony lists its weight at 192 grams and describes a lightweight headband designed for comfort. That combination makes it a sensible fit for long stretches of listening at home, during a commute, or while working. It also gives the headphones more presence than an in-ear pair, which may be welcome if you prefer not to put silicone tips in your ears.
Sony’s listed battery life is up to 35 hours, and a three-minute charge is specified to provide up to an hour of playback. The headphones also offer adjustable Ambient Sound mode with 20 settings, plus Adaptive Sound Control that adjusts to the surrounding environment. Those features give you more ways to choose between reducing surrounding noise and letting some of it through. Multipoint connection allows pairing with two Bluetooth devices, while beamforming microphones support hands-free calls.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
I’d consider Sony for someone who wants a versatile over-ear pair for music, calls, and everyday listening, especially if battery life and noise-control options are priorities. I’d skip it for running if a headband feels cumbersome or you want a product specifically described as sweat and splashproof. Its listed features don’t establish water resistance, so I wouldn’t assume it is intended for sweaty workouts.
The Sudio N3 is an in-ear Bluetooth earbud set with active noise cancellation. Its silicone eartips come in four sizes, giving you options to find a fit that feels secure and comfortable. That matters for running: a well-fitting earbud can be easier to manage than a headband, and the compact case is described as small enough to sit in a pocket. Sudio also specifically describes the N3 as sweat and splashproof.
The N3 lists up to 30 hours of playtime. It also supports multipoint connection, and its design uses 20% recycled plastics. Those details make it a practical option for someone who wants small earbuds for more than one part of the day—not just a workout. Its active noise cancellation may help reduce background noise, but the provided features do not give a noise-cancellation adjustment range comparable to Sony’s 20-level Ambient Sound mode.
I’d choose Sudio for running, portability, and a fit that can be adjusted with different eartip sizes. I’d look elsewhere if you specifically want over-ear headphones, Sony’s stated 35-hour battery life, or clearly described ambient-sound controls. The Sudio listing identifies the product as the N3 Pro, although the model name and supplied color details vary across the product information; the core comparison here is its in-ear design and listed features.
• Best fit for running → Sudio N3. Its in-ear design, four eartip sizes, and stated sweat and splash resistance make it the more practical match for a workout.
• Best for long stretches between charges → SONY WH-CH720N. Sony lists up to 35 hours, compared with Sudio’s up to 30 hours.
• Best for adjustable awareness → SONY WH-CH720N. Its Ambient Sound mode has 20 settings, and Adaptive Sound Control is also listed.
• Best for a pocketable setup → Sudio N3. The earbuds and petite case are designed to be easy to carry, unlike an over-ear headband.
• Best for avoiding silicone eartips → SONY WH-CH720N. Its over-ear format avoids the in-ear fit that some listeners prefer not to use.
• Best for a clearly stated sweat-and-splash-resistant design → Sudio N3. That protection is specifically included in its feature description.
• Best for switching between two paired devices → Both. Sony specifies connection to two Bluetooth devices at once; Sudio also lists multipoint connection.
• Best for hands-free call details → SONY WH-CH720N. Its beamforming microphones and Precise Voice Pickup Technology are described for clearer voice pickup.
The phrase “best open ear headphones for running” gets used loosely, but neither of these is an open-ear model. Sony covers the ear, while Sudio sits inside it. If hearing more of your surroundings is central to your running routine, neither product’s listed design makes it an open-ear choice. Sony’s adjustable Ambient Sound mode is the more explicit option for letting in environmental sound, but it is still an over-ear headphone with active noise cancellation.
Likewise, anyone searching for the “best noise cancelling headphones for running” should separate noise reduction from workout suitability. Both products list active noise cancellation, but only Sudio is described as sweat and splashproof. Sony offers more specific ambient-control features and longer stated battery life. For a run, the fit and resistance details may matter just as much as noise cancellation.
If by “best bluetooth headset for running” you mean something compact that stays in your ears and has stated sweat protection, Sudio is the closer match on paper. If you mean a Bluetooth listening option for calls and daily wear, Sony’s beamforming microphones and over-ear comfort details are relevant. Neither spec sheet establishes how either model will feel during a particular person’s run, so fit preference remains important.
For running, I’d choose Sudio N3. Its in-ear design, four tip sizes, pocketable case, and stated sweat and splash resistance align more directly with a workout than Sony’s over-ear format.
I’d pick the SONY WH-CH720N instead for everyday listening where I value longer listed battery life, adjustable ambient sound, and detailed call features.
My decision comes down to use: Sudio for the run, Sony for a more feature-rich over-ear routine.
Sudio is the more workout-oriented choice based on its in-ear design, four eartip sizes, and stated sweat and splash resistance. Sony is an over-ear headphone, and its listed features do not specify sweat or splash resistance.
Sony lists up to 35 hours of battery life, while Sudio lists up to 30 hours of playtime. Sony also specifies quick charging: a three-minute charge provides up to an hour of playback.
Both list active noise cancellation, but the available specifications do not provide a direct comparison of how much noise each reduces. Sony additionally lists 20 Ambient Sound settings and Adaptive Sound Control; Sudio’s supplied features do not specify comparable adjustment levels.
Sony’s WH-CH720N lists an adjustable Ambient Sound mode with 20 settings. That gives it a clearer stated option for tuning how much surrounding sound comes through, though it remains an over-ear headphone rather than an open-ear design.
