• MEDca Device Headphones Pair — biggest strength: Long battery life of up to 50 hours, and the batteries are standard, easily replaceable ones. It also ships as a complete package in a gift box with a carry bag.
• MEDca Device Headphones Pair — biggest trade-off: It uses a 3.5mm audio output connection, and it has no noise control at all. So it is tied to devices with a headphone jack, and it will not isolate you from background sound.
• Zopsc Type C — biggest strength: Open-ear ear-hook design with a 14mm dynamic driver and a built-in noise canceling microphone. It stays put during hard workouts and keeps you aware of your surroundings.
• Zopsc Type C — biggest trade-off: It is wired with a Type C connection, so it is useless with devices that only have a 3.5mm jack, and there is no battery to fall back on.
• Who each pick is for: MEDca suits someone who wants a simple, long-running listening device for everyday use and sports, plus a gift-ready package. Zopsc suits someone who wants a wired, open-ear set for running, cycling or commuting while staying alert.
The MEDca Device Headphones Pair is an in-ear model in red, built from plastic and silicone, and it weighs barely anything at 9.07 grams. The design brief here is simplicity plus stamina rather than audiophile ambition. You get different mode settings and volume control, so you can dial in a combination that suits what you are listening to, and the brand notes the MZ-38 delivers powerful, clear performance. There is no noise control on board, which is worth being honest about: this is not a set that shuts the world out.
Where it really separates itself is the battery. MEDca rates it for up to 50 hours of use, and when it eventually runs down you swap in commercial, easy-to-find batteries rather than hunting for a charging cable. That matters for anyone who has been burned by a sealed battery dying at the wrong moment. It arrives with three LR44 batteries included, all accessories packed in a gift box, and a portable carry bag. The instruction manual is written to be straightforward, and the brand backs it with a satisfaction guarantee.
In my opinion, this is the pick for someone who wants a dependable pair of in-ear headphones for everyday sports and outdoor use, a long trip, or as a gift — especially if their device still has a 3.5mm audio output. You should skip it if you need a USB-C connection, if you want active noise cancellation, or if you want a microphone for calls, since the data sheet lists none of those.
The Zopsc Type C takes the opposite approach. It is a wired ear-hook headphone in black, and it hooks over your ear instead of sealing into the canal. That open-ear shape is the whole point. Because nothing plugs your ear, ambient sound stays audible — traffic, announcements, a training partner talking to you. The product is explicitly aimed at running, cycling and commuting for exactly that reason, and it is described as safe for driving and exercising too.
On the audio side, Zopsc uses air conduction with a 14mm dynamic driver, which the brand says delivers clear vocals and deep bass. There is also a built-in noise canceling microphone, so calls should come through crisply even in a noisy environment. The ergonomic ear hooks are meant to hold firm during high-strength workouts — the brand describes them as lightweight and barely noticeable, with a stable fit across ear shapes and no slipping.
Two things to weigh before buying. First, the connection is Type C, so you need a device with a USB-C port; there is no 3.5mm option and no battery to keep it running when the cable is out. Second, it is a plug-and-play wired earbud in a plastic shell, and it comes with a 90-day manufacturer warranty. In my opinion, this is the right choice for a runner or cyclist who wants music and calls without blocking out the world, and the wrong choice for anyone who wants a wireless, long-battery everyday set.
• Best for battery life → MEDca Device Headphones Pair. Up to 50 hours, and you can replace the batteries with ordinary commercial ones instead of recharging.
• Best for staying aware of traffic and surroundings → Zopsc Type C. The open-ear ear-hook design keeps ambient sound audible while you listen.
• Best for calls → Zopsc Type C. It has a built-in noise canceling microphone. The MEDca data sheet lists no microphone.
• Best for gift-giving → MEDca Device Headphones Pair. It comes with all accessories in a gift box and a portable carry bag.
• Best for high-intensity workouts → Zopsc Type C. The ergonomic ear hooks are designed to stay in place without slipping.
• Best for older devices and headphone jacks → MEDca Device Headphones Pair. It connects over a 3.5mm audio output; the Zopsc is Type C only.
• Best for deep bass and clear vocals → Zopsc Type C. The 14mm dynamic driver is the larger, more audio-focused piece of hardware here.
• Best for a hearing-improvement use case → MEDca Device Headphones Pair. That is the recommended use listed for it, and the mode settings and volume control support it.
If I had to pick one, I would buy the MEDca Device Headphones Pair. In my opinion the 50-hour battery, the replaceable standard batteries, the 3.5mm compatibility and the complete gift-box package make it the more flexible everyday purchase — it works with more devices, runs far longer, and never leaves you hunting for a charger. I would only switch to the Zopsc Type C if my priority were running, cycling or commuting with an open-ear fit, a microphone for calls, and full awareness of what is going on around me. Those are two genuinely different jobs. Pick the one that matches yours, and check the current price on Amazon before you commit.
No. It connects through a 3.5mm audio output, so it needs a device with a headphone jack. It runs on three included LR44 batteries, which you can replace with commercially available ones.
No. It is a Type C wired headphone, so your device needs a USB-C port. The data sheet lists no 3.5mm option and no battery, so it only works while plugged in.
The Zopsc Type C does. It has a built-in noise canceling microphone for crisp calls in noisy places. The MEDca Device Headphones Pair has button controls and volume control, but no microphone is listed.
In my opinion, the Zopsc Type C. Its ear-hook design is made to stay secure during high-strength workouts and the open-ear shape keeps you aware of traffic. The MEDca is fine for everyday sports and outdoor use, but it has no noise control and seals into the ear.
