If you want a lightweight on-ear fit that stays comfortable for hours and a wider high-frequency reach, choose Audio Technica ATH-EQ300M; if you need in-ear isolation with on-cord volume control and a long cable for TV listening, choose 100SEASHELL Headphones Without Mic.
• Audio Technica ATH-EQ300M — biggest strength: A genuinely featherweight on-ear design (about 0.7 oz / 20 g) with a thin housing, 28 mm dynamic drivers, and a frequency range that extends up to 24,000 Hz.
• Audio Technica ATH-EQ300M — biggest trade-off: It's an ear-fit/on-ear shape, so it won't seal out background noise the way an in-ear can; its passive noise cancellation only does so much.
• 100SEASHELL Headphones Without Mic — biggest strength: In-ear design with interchangeable ear tips and built-in volume control right on the cord, plus a long cable meant for private TV listening from a distance.
• 100SEASHELL Headphones Without Mic — biggest trade-off: Its stated frequency range tops out at 20,000 Hz and it has no noise control at all, so it's a straightforward listening tool rather than a hi-fi one.
• Buy the Audio Technica if fit, light weight, and an open, airy on-ear feel matter most to you.
• Buy the 100SEASHELL if you want in-ear tips, cord-mounted volume, and a long reach for watching TV without disturbing anyone.
The ATH-EQ300M is built around one idea: get the earpiece off your ear canal and keep the whole thing light. At roughly 20 grams, with an ultra-thin housing, it's the kind of headphone you forget you're wearing. That matters if you wear headphones for long stretches — a commute, a full workday at a desk, an evening of podcasts. On-ear, flat-shaped earpieces rest against the ear rather than plugging into it, which is exactly why people who dislike the "stuffed" feeling of in-ears gravitate here.
On the audio side, the sheet lists 28 mm dynamic drivers, 20 ohm impedance, and a frequency range reaching 24,000 Hz. A 20 ohm impedance is on the low side, which generally means it's easy to drive from a phone, laptop, or basic player without needing a dedicated amp. The frequency range extending well past the audible top end is the detail that ties into a flatter, more even tonal presentation — it gives the driver headroom across the highs rather than rolling off early. In my opinion, that's the strongest argument for this model if your priority is a neutral, non-boomy listen.
The cord is a 1.2 m wired connection with a 3.5 mm jack, and it includes a wired remote with media control, so you can handle playback without reaching for your device. It's wired-first, and the sheet also lists Bluetooth under style and connectivity — treat the wired 3.5 mm path as the primary, everyday connection.
100SEASHELL Headphones Without Mic: Who It's For
The 100SEASHELL pair is a different tool entirely, and the name tells you the intent: no microphone. This is private-listening gear. The headline feature is the extra-long cord paired with built-in volume control, which together solve a very specific problem — watching TV at a comfortable distance without cranking the speakers and annoying everyone else in the room. If that's your scenario, the design speaks directly to it.
It's an in-ear model with rounded-tip earpieces and a plastic enclosure, and it ships with interchangeable ear tips in different sizes. That's a real practical win: tips that actually fit your ears are the difference between a loose, thin sound and a decent one. The sheet lists a dynamic driver and a frequency range of 20 Hz to 20,000 Hz — the standard full-audible-band spec, covering the lows through the highs. Clear, crisp sound for music, podcasts, and movies is the stated aim, and 3.5 mm wired connectivity keeps it compatible with TVs, phones, tablets, and laptops.
Two things to know before you buy. First, there's no noise control listed — no passive cancellation, no active anything — so isolation depends entirely on how well the tips seal. Second, the noise-reduction trade-off cuts both ways: less isolation is a downside on a noisy bus, but on-ear openness is a downside when you specifically want to block out a TV's ambient hum or a partner's conversation.
Who should buy it: TV watchers who want cord-mounted volume and a long reach, plus anyone who prefers in-ear tips and wants size options. Who should skip it: listeners chasing maximum high-frequency extension or any form of noise control.
Side-by-Side: Which Should You Choose?
• Best for private TV listening → 100SEASHELL Headphones Without Mic — the extra-long cord plus on-cord volume control is purpose-built for it.
• Best for high-frequency reach → Audio Technica ATH-EQ300M — its range extends to 24,000 Hz versus 20,000 Hz on the 100SEASHELL pair.
• Best for in-ear isolation and tip fit → 100SEASHELL Headphones Without Mic — interchangeable ear tips in different sizes, rounded-tip in-ear shape.
• Best for on-device playback control → Audio Technica ATH-EQ300M — a wired remote with media control is built in.
• Best for volume adjustment without touching your device → 100SEASHELL Headphones Without Mic — the volume control sits on the cord.
• Best for easy-to-drive, low-impedance listening → Audio Technica ATH-EQ300M — 20 ohm impedance plays nicely with phones and laptops.
• Best for a simple, no-mic listening setup → 100SEASHELL Headphones Without Mic — no microphone, just playback, wired over 3.5 mm.
If I had to pick one, I'd buy the Audio Technica ATH-EQ300M. In my opinion, the combination of a 20 g on-ear build, 28 mm dynamic drivers, 20 ohm impedance, and a frequency range reaching 24,000 Hz makes it the more versatile everyday headphone — comfortable for hours and tonally even across the highs. I'd recommend the 100SEASHELL Headphones Without Mic instead only if your main use is private TV listening with cord-mounted volume and a long cable. Both are wired 3.5 mm designs, so your decision really comes down to on-ear comfort versus in-ear convenience.
Yes, and it's the clearest spec difference here. The ATH-EQ300M extends to 24,000 Hz, while the 100SEASHELL pair covers 20 Hz to 20,000 Hz. A wider range suggests more high-frequency headroom, which tends to support a flatter, more even presentation — though it's one spec, not the whole story.
Are these headphones wired or wireless?
No. The data sheet lists no noise control for them, so isolation comes only from how well the interchangeable ear tips seal. The ATH-EQ300M lists passive noise cancellation, but as an on-ear design it also won't block sound the way a deep in-ear seal can.
The 100SEASHELL Headphones Without Mic, in my opinion. Its extra-long cord and built-in volume control are designed for private listening from a comfortable distance, which is exactly the TV scenario. The ATH-EQ300M's 1.2 m cord is better suited to a phone or laptop nearby.
