If you want a durable, wired on-ear solution for kids or travelers who prioritize simplicity and tangle-free cords, choose ELECDER i37; if you need modern wireless freedom with active noise cancellation and a massive 70-hour battery for serious jogging, choose TOZO HA1.
• ELECDER i37: Offers a lightweight, foldable design with a tangle-proof cloth cord that is perfect for school and travel, but lacks Bluetooth connectivity or any built-in controls.
• TOZO HA1: Delivers advanced Bluetooth 5.4 performance with active noise cancellation and an impressive 70-hour playtime, though it is heavier and requires charging.
• The Verdict: The ELECDER i37 is the practical choice for stationary listening or young users, while the TOZO HA1 is the superior option for active lifestyles like running.
The ELECDER i37 is designed with a specific set of priorities in mind: durability, simplicity, and portability without the hassle of batteries. This is a wired headphone that relies on a standard 3.5mm jack, which means it works instantly with almost any device that has a headphone port, from older laptops and Chromebooks to tablets and smartphones. There is no setup, no pairing process, and no waiting for a charge. You plug it in, and you are ready to listen. The cable itself is a standout feature; it is constructed from high-quality cloth material, measuring 4.9 feet (1.5 meters) long. This specific design choice makes the cord resistant to tangling, a common frustration for anyone who tosses headphones into a bag.
Its physical construction leans heavily into the "rugged" category. Weighing only 5.6 ounces, it is incredibly light, making it comfortable enough for extended wear without feeling like a burden on the ears. The ear cups are placed on the ear rather than over them, and the headband is adjustable to fit various head shapes, from small children to adults with smaller frames. The folding mechanism allows it to collapse down significantly, fitting easily into a suitcase, backpack, or even a coat pocket. For parents buying for school use, this foldability is a major plus. The sound quality comes from 40-millimeter dynamic drivers capable of reproducing frequencies between 20 Hz and 20,000 Hz, offering stereo bass that is clear enough for classroom videos, music, and casual gaming.

However, this product is not for everyone. It lacks a microphone, remote, or volume control on the headset itself. If you need to answer calls or adjust volume without reaching for your phone, this model will frustrate you. It also does not have wireless capabilities, tethering you to your device. This makes it less ideal for active movement where cables can snag or get in the way. It is best suited for students sitting at a desk, travelers on a plane who want to watch movies without worrying about battery life, or parents looking for a reliable, break-resistant pair of headphones for younger children who might be rough with their gear.
The TOZO HA1 represents a shift toward high-performance wireless audio designed for the modern, active user. At its core is Bluetooth 5.4 technology, which provides a robust connection with a range of up to 20 meters. This ensures that as you move around your home, office, or neighborhood, your audio stream remains stable without dropouts. The headline feature here is the battery life. With an average life of 70 hours, this headphone eliminates the anxiety of frequent charging. Even if you use it daily for long periods, you can go weeks between charges. It charges via USB-C, taking about two hours to reach full capacity, a reasonable trade-off for such a massive runtime.
Where the ELECDER shines in simplicity, the TOZO HA1 excels in customization and isolation. It features Active Noise Cancellation (ANC), a critical feature for anyone trying to focus in noisy environments or block out wind and traffic noise during outdoor activities. The ear placement is "Over Ear," meaning the cushions surround the ear completely rather than resting on it, providing better passive isolation alongside the electronic ANC. The sound profile is highly flexible; users can access 32 custom EQ modes through a dedicated app to tailor the bass and treble to their personal taste. Whether you prefer deep, thumping bass for workout playlists or balanced vocals for podcasts, the TOZO HA1 gives you the tools to shape the audio exactly how you want it.
The build includes a low-latency mode that reduces delay to just 78 milliseconds. This is essential for watching videos or playing games where lip-sync matters, ensuring the audio matches the visual perfectly. The controls are button-based and located on the ear cup, allowing you to manage media playback and calls directly on the headset. While it weighs more at 235 grams compared to the ELECDER, the ergonomic oval design is meant to maximize comfort during long listening sessions. This is the headphone for the commuter, the gym-goer, or the traveler who needs to disconnect from the world but stay connected to their music.
• Best for battery life → TOZO HA1: With 70 hours of continuous playtime, it far outlasts the ELECDER i37, which has no battery but is always ready when plugged in.
• Best for active movement (jogging) → TOZO HA1: The wireless Bluetooth 5.4 connection removes the risk of a cord getting caught on branches or gym equipment, while ANC blocks out ambient noise.
• Best for zero maintenance → ELECDER i37: No charging required, no firmware updates, and no pairing issues; just plug and play.
• Best for noise isolation → TOZO HA1: Active Noise Cancellation combined with over-ear cups creates a quiet bubble that the on-ear, non-isolating ELECDER cannot match.
• Best for durability against tangles → ELECDER i37: The cloth-wrapped, tangle-proof wire is superior for storage in tight spaces compared to coiled wires that can knot.
• Best for call quality → TOZO HA1: Equipped with a microphone and button controls for calls, whereas the ELECDER i37 has no microphone capability.
• Best for small heads/kids → ELECDER i37: Its lighter weight (5.6 oz) and on-ear design make it more suitable for children than the heavier, bulkier over-ear TOZO.
• Best for sound customization → TOZO HA1: The ability to select from 32 different EQ modes offers a level of sonic control the fixed-sound ELECDER cannot provide.
When I look at these two options specifically for someone who wants a headphone for jogging, the choice becomes clear immediately. Running involves movement, sweat, and the need to stay aware of your surroundings while blocking out distractions. The TOZO HA1 is the only logical choice here because the wireless design prevents the cord from swinging or snagging, and the Active Noise Cancellation helps you maintain your rhythm without being overwhelmed by city traffic or wind noise. The 70-hour battery ensures you never have to stop your routine to find a charger. While the ELECDER i37 is a fantastic, sturdy device for a student desk or a car ride, the lack of wireless freedom makes it unsuitable for on ear headphones for jogging. In my opinion, if you are serious about fitness and mobility, the TOZO HA1 is the investment you should make.
The TOZO HA1 is excellent for running due to its secure over-ear fit and wireless Bluetooth 5.4 connection, while the ELECDER i37 is not recommended for jogging because the wired cord can interfere with movement.
No, the TOZO HA1 boasts an impressive 70-hour battery life, meaning you can likely go several weeks of regular use before needing to recharge it via the included USB-C cable.
No, the ELECDER i37 does not include a built-in microphone, remote, or volume controls, so it cannot be used for answering phone calls or adjusting audio settings remotely.
The TOZO HA1 offers 32 custom EQ modes accessible through a mobile app, allowing you to fine-tune the bass and treble, whereas the ELECDER i37 offers a fixed stereo sound profile.
