If you want a simple wired headset for workout use around home or a studio, choose Sony MDR7506; if you need wireless listening, active noise control, and long battery life for workout sessions, choose JBL Live 770NC. I’d pick JBL for most people exercising away from a desk, while Sony makes more sense when a cable and straightforward listening are acceptable. Neither is a dedicated sports design, so fit and workout intensity matter.
Sony MDR7506 vs JBL Live 770NC at a Glance
• Sony MDR7506: A wired, closed-ear design with 40 mm drivers and a foldable build; the long, non-detachable cord can get in the way when moving.
• JBL Live 770NC: Wireless Bluetooth listening, adaptive noise cancelling, Smart Ambient, and up to 65 hours of battery life; it needs charging and weighs more than the Sony.
• Sony is for: People who want a direct wired connection and headphones suited to home audio or professional audio systems.
• JBL is for: People who want wireless convenience, adjustable awareness of surrounding sounds, and battery-powered listening.
• For workouts: JBL’s lack of a permanently attached cable is a practical advantage, but neither product’s listed features establish it as a workout-specific fit.
The Sony MDR7506 is a wired over-ear headphone with 40 mm drivers, a closed-ear design, and a stated frequency range of 10 Hz to 20 kHz. Its strength is straightforwardness: connect it through its cable and listen, without relying on a wireless connection or battery. The closed design is intended to reduce external noise, while the foldable construction and supplied soft case make it easier to put away or carry.

For a workout buyer, I would consider the Sony only if the session is mostly stationary and a cable will not bother you. It does not offer Bluetooth, active noise cancelling, or the convenience of listening without a physical connection. The supplied information describes a rugged construction, but it does not specify a workout-oriented fit or any sweat-resistance feature. If you want a lightweight wireless headset for workout movement, the Sony’s long fixed cord makes it the less natural match.
The JBL Live 770NC is an over-ear Bluetooth headphone built around wireless listening. Its 40 mm drivers support JBL Signature Sound and JBL Spatial Sound, while Bluetooth 5.3 provides the wireless connection. The main practical difference from the Sony is the set of listening controls: True Adaptive Noise Cancelling is designed to reduce surrounding sound, and Smart Ambient lets more of the environment through when you want awareness without taking the headphones off.
That flexibility can make the JBL easier to use across different settings. You can listen without managing a cable, use noise control in a distracting space, or switch toward hearing nearby sounds. It also has automatic play-and-pause behavior when you remove and put on the headphones. Battery life is listed as up to 65 hours, or up to 50 hours with Bluetooth and noise cancelling enabled. A five-minute charge is described as providing up to four hours of music, and a full charge takes about two hours.
For workouts, wireless operation is a meaningful advantage over the Sony’s fixed cord. Still, the JBL is an over-ear headphone, and the available details do not specify a workout-specific retention design or sweat resistance. Its listed weight is 15.68 ounces, so buyers who prioritize a lightweight feel should take that figure into account. It may suit lighter exercise or sessions where over-ear headphones feel comfortable, but I would not assume it is the right choice for every vigorous routine. It also does not provide a built-in wired fallback through a headphone jack; the listed connectivity is Bluetooth.
Side-by-Side: Which Should You Choose?
• Best for avoiding a cable during movement → JBL Live 770NC. Its Bluetooth connection removes the Sony’s permanently attached 9.8-foot cord from the workout equation.
• Best for a direct wired setup → Sony MDR7506. It connects by cable and includes a 1/4-inch adapter, which may be useful with compatible home or professional audio equipment.
• Best for choosing how much outside sound you hear → JBL Live 770NC. Adaptive noise cancelling and Smart Ambient offer different ways to manage the listening environment.
• Best for long listening without a charging routine → Sony MDR7506. It is wired and does not depend on battery life. The JBL offers up to 65 hours, but it must be recharged.
• Best for workouts with a microphone-focused wireless setup → JBL Live 770NC, with a caveat. It is the wireless option, but the provided specifications do not give microphone performance details, so I would not promise call quality or treat it as a purpose-built workout headset.
• Best for packing away after use → Sony MDR7506. It folds for storage and comes with a soft case. JBL includes a carrying pouch, but the Sony’s listed foldable construction is a specific portability feature.
• Best for audio and video on a wireless connection → JBL Live 770NC. Its Video Mode is intended to keep sound and visuals in sync, while the Sony is a wired headphone without that wireless mode.
In my opinion, I would choose the JBL Live 770NC for most people deciding between these two for workout use. Wireless listening, adjustable awareness, and substantial stated battery life fit movement better than the Sony’s long, non-detachable cable. The Sony remains my pick for a stationary wired setup, especially when simple connection matters more than wireless features. For someone searching for the best earphones for workout, I’d still weigh exercise intensity and over-ear comfort carefully: neither product’s listed details establish a sports-specific fit. But between these two, I’d start with the JBL.
