If you want simple, lightweight wired headphones for a workout, choose Sony ZX Series; if you need wireless listening, active noise cancelling, and longer battery life, choose Focal BATHYS Over Ear. For most workouts, I would choose the Sony when ease and low-fuss portability matter more than isolation; the Focal is the more capable listening companion when its larger over-ear design suits the activity.
• Sony ZX Series: Lightweight on-ear design, folding swivel earpads, and a 3.5 mm wired connection; its main trade-off is having no wireless listening or noise control.
• Focal BATHYS Over Ear: Bluetooth, active noise cancelling, transparency mode, and over 30 hours of battery life; its main trade-off for workouts is a more involved, over-ear design that may be less convenient than a simple on-ear pair.
• Sony is for: Someone who wants straightforward wired headphones for music, travel, or an uncomplicated workout setup.
• Focal is for: Someone who wants wireless freedom and listening controls for commutes and other settings, and who prefers an over-ear headphone format.
• The key difference: Sony keeps the job simple; Focal adds wireless features, multiple connection options, and ways to manage outside sound.
• The name alone can make this comparison look like a contest between two similar headphones. Their designs tell a different story. The Sony MDR-ZX110 is a wired on-ear model; the Focal Bathys is a Bluetooth over-ear headphone with active noise cancelling. For exercise, those differences matter more than a spec-sheet showdown. A cable-free setup and sound modes may help in some routines, while a lightweight, uncomplicated wired pair may be easier to deal with in others.
The Sony ZX Series is the simpler choice. It has 30 mm dynamic drivers, a lightweight on-ear design, and a 3.5 mm connection. Its swivel, folding earpads make it easier to pack away, while the 1.2 m Y-type cable gives you a direct wired connection without needing to manage battery charge or Bluetooth pairing. The cord is described as tangle-resistant, a useful detail when headphones are frequently put in a bag between trips or sessions.
For a workout, its appeal is practical rather than feature-heavy. There is no battery to charge, and the wired connection avoids wireless setup. That can suit a stationary workout or a routine where a cable is not in the way. The 24-ohm impedance is another concrete part of its straightforward wired design, although it does not turn the headphones into a purpose-built sports model. The supplied information describes them as travel-oriented, not as having workout-specific construction or controls.
The trade-off is clear: the Sony has no noise control and no wireless connection. A cable may be inconvenient during movement, and the on-ear format does not offer the same ear coverage as Focal’s over-ear design. There is no stated water-resistance feature, so I would not assume it is meant to handle sweat or wet conditions. For someone searching for the best gaming headset for workout, the Sony’s wired connection may be useful with compatible equipment, but the listed features do not establish it as a gaming headset or identify a microphone.

Who should skip it: Skip the Sony if you want Bluetooth, active noise cancelling, a transparency mode, or a stated long-running battery.
In day-to-day use, this pair makes the most sense when the listening setup is already wired and the priority is keeping the headphones easy to carry. The folding swivel design supports that use, while the 3.5 mm plug gives it a familiar connection option. It is not the more flexible choice for someone who wants to move freely without a cord, switch between quiet and awareness modes, or use one pair across wireless and wired listening.
The Focal Bathys is the feature-rich option. It combines Bluetooth 5.1 with 3.5 mm and USB-C connections, so it is not limited to wireless listening. Its 40 mm aluminum-magnesium drivers are the basis of its audio design, while the listed frequency range extends from 15 Hz to 22 kHz. Those figures describe the hardware and range; they do not, on their own, guarantee how a particular listener will perceive its sound.
For travel and everyday listening, the Bathys brings features the Sony does not have. Active noise cancelling has two listed modes, and a transparency mode is available when you want to interact with your surroundings. The stated battery life is over 30 hours with Bluetooth and active noise cancelling in use. Fast charging is also specified: 15 minutes of charging provides five extra hours of listening. That makes it a strong candidate for anyone looking for the best fast charging on ear headphones for workout, though it is an over-ear design, not an on-ear model.
The Bathys uses a magnesium yoke and aluminum mechanical construction, along with a real-leather and microfiber headband. Its earpads are described as replaceable, which is a practical design point for someone considering longer-term ownership. It also comes with a more elaborate set of listening features than the Sony, including compatible Bluetooth codecs and an app with equalizer and other settings. These are useful options if you want to tailor wireless listening, but they also mean the Bathys is a more complex headphone than a basic wired pair.
Who should skip it: Skip the Bathys if you specifically want a simple, lightweight on-ear headphone with no battery to recharge, or if you need confirmed workout-focused durability; no water-resistance rating is provided.
For exercise, the strongest Bathys argument is freedom from a headphone cable, paired with battery capacity that can cover many listening sessions between charges. Its over-ear format and noise-control features may suit walking or a gym setting where you want to choose between immersion and awareness. But it is not automatically the right workout pick for every routine. The available information does not describe a secure sports fit or sweat protection, and the over-ear design may be less appealing if your workout calls for minimal, compact equipment.
• Best for a no-battery wired setup → Sony ZX Series. Its 3.5 mm connection works without relying on a rechargeable headphone battery.
• Best for wireless movement → Focal BATHYS Over Ear. Bluetooth 5.1 removes the headphone cable from the connection.
• Best for stated battery life → Focal BATHYS Over Ear. It is specified for over 30 hours with Bluetooth and active noise cancelling enabled.
• Best for quick top-ups → Focal BATHYS Over Ear. A 15-minute charge is stated to provide five extra listening hours.
• Best for choosing how much outside sound to hear → Focal BATHYS Over Ear. It offers two noise-cancelling modes and a transparency mode.
• Best for folding portability → Sony ZX Series. Its swivel, folding earpads are designed to make the headphones easier to carry.
• Best for multiple connection options → Focal BATHYS Over Ear. It supports Bluetooth, 3.5 mm, and USB-C connections.
• Best for a simple workout companion → Sony ZX Series, if a cable fits your routine. Choose Focal instead if wireless listening and battery life are more important than a basic design.
Neither headphone is specifically established by the supplied details as a dedicated sports model. That distinction matters. A workout can mean a stationary cycling session, a walk, or a routine with plenty of movement; those situations put different demands on fit and cable management. The Sony’s light, folding design and wired simplicity make a reasonable case for controlled, low-fuss use. The Bathys avoids the cable and adds sound-control options, but the specs do not confirm sweat resistance or a sports-oriented fit.
Buying Considerations
Separate battery convenience from workout suitability. The Bathys has a clear advantage if you want long listening between charges or a quick charging top-up. Its stated over-30-hour battery life and five-hours-from-15-minutes charging detail are meaningful convenience features. They do not establish sweat protection, a secure fit during exercise, or any other sports-specific benefit. Likewise, the Sony’s lack of a battery means no charging routine, not that it is more durable for workouts.
Consider whether isolation or awareness matters more. The Bathys lets you choose active noise cancelling or transparency mode. That flexibility may help when you want to focus on audio in one setting and hear more of your surroundings in another. The Sony has no noise control, which keeps its feature set basic. Neither set of details proves how much sound either headphone blocks in a particular environment.
Account for the way each one packs. The Sony’s swivel, folding earpads are a practical portability feature. The Bathys offers a different sort of versatility through wireless, USB-C, and 3.5 mm connections, plus its listed app settings. If your priority is a pair that folds for a bag, Sony has the more directly relevant design detail. If you want several ways to connect and adjust listening, Focal has the broader feature set.
Be cautious about workout claims. Neither data sheet lists a water-resistance rating. If a workout involves heavy sweating or exposure to rain, do not treat either headphone as protected on the basis of these specifications. For the same reason, shoppers looking for the best long battery life on ear headphones for workout should note that the Bathys is over-ear, while the Sony’s specifications do not list a battery at all. The right choice depends on which trade-off matters more: a cord or a rechargeable wireless design.
If price is part of your decision, check the current price on Amazon before choosing; the feature details alone do not settle which one is better value for your budget. I would make the final call based on how you will wear them and connect them, not on an assumption that either model is built specifically for exercise.
I would choose the Sony ZX Series for a simple, stationary workout where a cable is no problem and I want folding portability without managing battery charge.
I would choose the Focal Bathys for a workout routine where wireless freedom, longer stated battery life, and the choice of noise cancelling or transparency matter more.
My overall pick for someone who wants one more versatile listening setup is the Focal, because it supports Bluetooth, USB-C, and 3.5 mm connections.
For the workout use case, though, neither has stated water resistance, so I would not treat either as a confirmed sweat-ready sports headphone.
The Bathys is wireless and has active noise cancelling and transparency mode, while the Sony is a lightweight, wired on-ear model. Choose based on whether avoiding a cable or keeping the setup simple matters more. Neither product information sheet specifies water resistance.
The Bathys is specified for over 30 hours of use with Bluetooth and active noise cancelling, and a 15-minute charge provides five extra listening hours. The Sony is wired, and no rechargeable battery life is listed for it.
The Sony connects through a 3.5 mm audio plug and is listed as a wired headphone. That means the listed design does not depend on Bluetooth battery life, though the device you connect it to may have its own power needs.
That depends on which features you will use. The Bathys adds Bluetooth, noise-control modes, multiple connection options, and a long stated battery life; the Sony offers a simpler wired setup and folding swivel earpads. Check the current price on Amazon if budget is part of your decision, then weigh those differences against your routine.
