• 100SEASHELL Long Cord — biggest strength: a 10 FT cable, so you can walk across the room, sit back on the sofa or keep the buds in while you work, plus a 3.5 mm plug that fits TVs, computers and tablets.
• 100SEASHELL Long Cord — biggest trade-off: it is offered with or without a microphone, and the version that ships without one is the one meant for TV watching — so don't expect hands-free calls.
• ACANDYA USB C Earbuds — biggest strength: USB Type-C connectivity with an inline microphone and remote, a DAC chip for stereo playback, and a storage case for carrying.
• ACANDYA USB C Earbuds — biggest trade-off: it only works with USB-C devices that have no 3.5 mm jack — no adapters, no legacy gear.
• Pick 100SEASHELL if your listening happens at a distance from a TV, desktop or tablet with a headphone socket.
• Pick ACANDYA if your listening happens on a phone or tablet that dropped the headphone jack and you want to take calls.
The 100SEASHELL Long Cord is all about reach. Its defining feature is a 10 FT (roughly 3 m) cable, which is a very different proposition from the short cables bundled with most in-ear buds. That length is the whole point: you plug into a TV, a desktop computer, a tablet or a sound card and then actually move around the room without yanking the buds out of your ears. For someone who watches TV late at night with the volume up and the room quiet, that's a genuinely useful design decision rather than a marketing line.
Inside, there's a 10 mm dynamic driver with a 32 ohm impedance and a 20 Hz – 20,000 Hz frequency range, which is a standard full-range spec for wired in-ear audio. The listing describes enhanced bass, clear treble and a tri-band balance, and passive noise reduction is claimed through the fit rather than electronics. The hardware backs up the comfort story too: a metal shell with an ergonomic angle, three sets of ear tips (S/M/L), and a wire clip for keeping the cable out of the way. The magnetic buds snap together for tangle-free storage. The cable itself is TPE, which is the flexible, rubbery jacket that tends to survive pockets and couch cushions better than stiff plastic.
Who should buy it? Anyone whose audio source still has a 3.5 mm jack and who is tired of a short cord. TV watchers, students at a desk, office workers, people on a treadmill, and anyone who wants to keep their phone across the room while listening. The brand even notes the buds are "suitable for watching TV and working," and that matches the design.
ACANDYA USB C Earbuds: Who It's For
The ACANDYA USB C Earbuds solve the opposite problem. Modern phones and tablets keep deleting the 3.5 mm socket, and this set plugs straight into a USB Type-C port — no dongle, no adapter, no fuss. The compatibility list is unusually long: iPhone 15/16/17 family, Samsung Galaxy S21 through S26 including the Ultra models, Note 20, Galaxy Tab S-series tablets, Google Pixel 5 through 10, OnePlus 6T through 11, iPad 10th gen, iPad Air, iPad Pro and iPad Mini 6th, plus Motorola Edge and Razr models. The catch is written right into the listing: it's for USB-C port devices without a 3.5 mm jack. If your device still has a round headphone hole, this isn't aimed at you.
The feature set is built around convenience. There's an inline microphone and a remote, so you can take hands-free calls, switch songs and adjust volume without unlocking your phone — the control method is a physical button on the remote, which many people prefer over touch controls because you can find it by feel. A DAC chip handles the digital-to-analog conversion inside the buds themselves, which is what allows USB-C audio to work at all, and the listing pairs it with "powerful bass" and HiFi stereo claims. The cable runs 1.2 m, a conventional pocket-and-desk length rather than the long-reach design of the 100SEASHELL set.
Comfort and carry are handled well for the category: an in-ear design with three ear tip sizes (medium pre-installed), sound isolation through the seal, and a protective storage case included in the box. The housing is aluminum, the color is white, and the listed weight is 0.08 kg — light enough to forget you're carrying them.
Who should buy it? Phone-first listeners. Commuters, students, call-takers, gamers on a laptop or tablet with USB-C, and anyone who wants one set that handles music and calls without an adapter dangling off the charging port. The age range is listed as adult and youth, so it's fine as a family spare too.
Who should skip it? Anyone with only 3.5 mm gear, anyone who needs a long cable, and anyone who wants a no-mic set. And if you own a mix of old and new devices, remember you can't adapt this one backwards with a simple plug.
• Best for TV watching from a distance → 100SEASHELL Long Cord. The 10 FT cable is the deciding spec here.
• Best for phones and tablets without a headphone jack → ACANDYA USB C Earbuds. USB-C straight in, no adapter.
• Best for hands-free calls → ACANDYA USB C Earbuds. Inline mic and remote with physical buttons.
• Best for devices with an old-school 3.5 mm socket → 100SEASHELL Long Cord. TVs, desktops, sound cards, electronic instruments.
• Best for cable length and freedom of movement → 100SEASHELL Long Cord. 10 FT versus 1.2 m is not a close race.
• Best for carrying around → ACANDYA USB C Earbuds. The included storage case makes a real difference in a bag or pocket.
• Best for fuss-free volume and track control while walking → ACANDYA USB C Earbuds. The remote is right on the wire.
• Best for a quiet-fit, no-electronics listening setup → 100SEASHELL Long Cord. Passive noise reduction plus three tip sizes and a wire clip.
• Best all-rounder for a modern Android or iPhone 15-and-later owner → ACANDYA USB C Earbuds. It matches the ports you actually own.
If I had to choose one for myself, I'd buy the ACANDYA USB C Earbuds — but only because my daily listening happens on a phone with no headphone jack, and the inline mic, volume remote and storage case cover music, calls and travel in one purchase. That said, I'd recommend the 100SEASHELL Long Cord without hesitation to anyone whose main listening is a TV or desktop, because a 10 FT cable plus a 3.5 mm plug is exactly what that setup wants and nothing in the ACANDYA set replaces it. In my opinion, this isn't a "which is better" question at all — it's a "which port and which cable length do you actually live with" question. Check your device's port first, then buy accordingly. If price matters to you, use the button on this page to check the current price on Amazon rather than relying on any number you've seen elsewhere.
Yes, in my opinion, if your TV or streaming device has a 3.5 mm output. The 10 FT cable is the feature you're paying for — it lets you sit back and move around instead of perching next to the screen.
They work with USB-C iPhone models — the 15, 16 and 17 families — plus iPads with a USB-C port. Older iPhones with a Lightning port are not on the compatibility list, so they won't work.
Only if you pick the version with a microphone. The listing offers both mic and no-mic variants, and the no-mic version is the one intended for TV watching and work listening.
Both use a 32 ohm dynamic driver with a 20 Hz – 20,000 Hz range, so on paper they're in the same class. The ACANDYA set adds a DAC chip and its listing emphasizes bass and stereo imaging; the 100SEASHELL set leans on a 10 mm driver and passive noise reduction. The bigger real-world difference is your source device, not the buds.
Only if that phone uses USB-C. The list covers Galaxy S21 through S26 and Pixel 5 through 10, all USB-C models. Anything with a 3.5 mm jack needs the 100SEASHELL set instead.
