If you want a genuinely long 10FT cord with an in-line-free 3.5mm plug for TV, desk and swim-side listening, choose 100SEASHELL Long Cord; if you need a USB-C wired earbud with a built-in mic, magnetic buds and a carry case for modern phones, choose ACAGET USB C Headphone. Both are wired noise isolating headphones, so neither depends on a battery to quiet the room around you — the difference is the connector, the cable and the extras. If you're shopping for swimming, that cable length and the passive seal matter more than any spec sheet headline.
• 100SEASHELL Long Cord — biggest strength: a 10FT cable that lets you move around the room, plus a 3.5mm jack that fits TVs, computers and tablets.
• 100SEASHELL Long Cord — biggest trade-off: it's a 3.5mm wired set with no USB-C option, so phones without a headphone jack need an adapter.
• ACAGET USB C Headphone — biggest strength: a native USB-C plug with an in-line mic and remote, magnetic buds and a storage case included.
• ACAGET USB C Headphone — biggest trade-off: it only works with USB-C devices, so older 3.5mm gear is off the table.
• Who each pick is for: 100SEASHELL for TV watchers, desk workers and anyone who wants free movement on a long cable; ACAGET for USB-C phone and tablet owners who need calls and control buttons.
The defining number here is the 10FT cable. That's the whole point of this model — it breaks the distance limit between you and the screen, so you can sit back on the couch, pace the room or step away from your laptop without dragging the device with you. The plug is a standard 3.5mm jack, and the brand lists compatibility with TVs, mobile phones, laptops, computers, tablets, sound cards and electronic instruments. If your TV or monitor still has a headphone socket, this is the simplest possible connection: plug in, done.
Sound is handled by a 10mm dynamic driver with a 20 Hz – 20,000 Hz frequency range and 32 ohm impedance. The brand describes full sound with enhanced bass and a tri-band balance, and lists passive noise reduction — the tips and the in-ear seal do the isolating work rather than electronics. You get three sizes of ear pads (S/M/L) plus a wire clip, which is exactly the kit you want if you're fitting them to different ears or keeping the cable from snagging. The ergonomic metal shell, magnetic buds and TPE cable round out a design built for long, low-effort sessions.
Who should buy it: TV and film watchers, people who work at a desk all day, students, and anyone who wants one pair of wired earbuds that travels between a television, a computer and a tablet. Who should skip it: anyone whose phone is USB-C only and who doesn't want to carry an adapter, and anyone who needs an in-line microphone on the cable — this version is the no-mic model, though the brand does note a microphone version exists if you need one for calls.
This one is built around the connector. The ACAGET uses a USB Type C plug, and the brand lists an enormous compatibility spread: iPhone 15/16/17 family, Google Pixel 8 through 10 series, Samsung Galaxy S22 through S26 plus the A-series and Z Flip/Fold lines, Galaxy Tab S7 through S10+, OnePlus 9 Pro through 15, and iPad Pro/Air/Mini. If you've already moved to a phone or tablet without a headphone jack, this is the plug that just works — no dongle, no guessing.
Inside, there's a 13mm dynamic driver, a 32 ohm impedance and a 20 Hz – 20,000 Hz range, with the brand pointing to a built-in Hi-Fi DAC for lossless-style output and deep bass. Noise control here is listed as sound isolation — the in-ear silicone tips seat into the canal and physically block ambient sound rather than cancelling it electronically. The 45-degree angled nozzle is designed to sit comfortably for long stretches, and three pairs of earplugs in different sizes are included so you can find your fit. There's also an in-line microphone and remote for volume, track skipping and answering calls, plus magnetic buds, a cable clip and a storage case in the box. ACAGET backs it with a six-month replacement service for defective units.
Who should buy it: USB-C phone, tablet and laptop owners who take calls, join video meetings, game or run, and who want magnetic buds that hang around the neck instead of tangling. Who should skip it: anyone still using 3.5mm-only gear, and anyone who wants a single pair that plugs into a TV headphone socket without an adapter.
Side-by-Side: Which Should You Choose?
• Best for modern USB-C phones and tablets → ACAGET USB C Headphone. Native Type C, no adapter needed.
• Best for phone calls and remote control → ACAGET USB C Headphone. It has an in-line mic and volume/remote buttons; the 100SEASHELL model here is the no-mic version.
• Best for sharing across older hardware → 100SEASHELL Long Cord. The 3.5mm jack covers TVs, computers, tablets and instruments.
• Best for workouts and running → ACAGET USB C Headphone. The angled in-ear fit, magnetic buds and cable clip are aimed at movement.
• Best for long sessions at a desk → 100SEASHELL Long Cord. The long cable plus the S/M/L ear tip kit and wire clip suit all-day wear.
• Best for travel and storage → ACAGET USB C Headphone. It ships with a storage case, cable clip and spare tips.
• Best for battery-free noise isolation → either one. Both are wired and rely on the in-ear seal rather than powered electronics.
If I were buying today, I'd take the ACAGET USB C Headphone, because the USB-C plug, the in-line mic and remote, and the included case cover the widest range of everyday jobs — calls, commuting, workouts and desk work on a modern phone. I'd pick the 100SEASHELL Long Cord instead if my main job were watching TV from across the room or working on a laptop with a headphone socket, where that 10FT cable and the 3.5mm jack win outright. For swimming specifically, I'd lean 100SEASHELL for the freedom and tip selection, but honestly, if you want the best low latency sports earbuds for swimming or a noise cancelling kids headset for swimming, check the current price on Amazon and decide based on which connector your device actually has. In my opinion, the plug matters more than any label here.
