• SoundMAGIC E10C biggest strength: tiny 15 g aluminium in-ear with a twisted anti-tangle cable, HD mic and volume remote — genuinely pocketable.
• SoundMAGIC E10C biggest trade-off: no boom mic, no surround processing, and the 20 Hz–16 kHz range is narrower on paper than the Kraken's.
• Amazon Renewed Razer Kraken Gaming biggest strength: big 50 mm drivers, software-enabled 7.1 surround on Windows 10 64-bit, and a retractable cardioid boom mic for voice chat.
• Amazon Renewed Razer Kraken Gaming biggest trade-off: 322 g on your head, a bulky over-ear frame, and it's a renewed unit with a 90-day limited warranty.
• Pick the E10C for commuting, phone calls, gym time and music-first listening.
• Pick the Kraken if you mostly sit at a desk or couch and talk to teammates while you play.
The E10C is a wired in-ear built around a simple idea: keep it small, keep it sturdy, keep the cable out of your way. The housing is aluminium, which is the part of a cheap earphone that usually fails first — a metal shell survives being shoved into a pocket or a bag compartment far better than plastic does. The 15 g weight is basically nothing, and the rounded-tip in-ear shape with multiple eartip options is meant to seal your canal so outside noise stays out and bass stays in.
On the audio side, SoundMAGIC fits a 16 ohm dynamic driver rated 20 Hz–16 kHz with 100 dB sensitivity. That low impedance matters more than it sounds: 16 ohms is easy to drive, so a phone, a laptop headphone jack or a cheap USB dongle will push it to a usable volume without an amp. The tuning is described as punchy bass with clear treble, and the design details back up the practical side — a twisted-pair cable that resists tangling and RF interference, a gold-plated 3.5 mm plug, plus an inline mic and volume remote for taking calls and skipping tracks.
The box is unusually complete for this class of earphone: three pairs of silicone dome tips, three pairs of flat silicone tips, one pair of double-flange tips, a Skype/VoIP adapter, a smartphone adapter, a cable clamp and a semi-rigid hard case. In my opinion the flat and double-flange tips are the underrated part — getting the right seal is the single biggest upgrade you can make to an in-ear, and most budget sets give you one tip style and call it a day.
Amazon Renewed Razer Kraken Gaming: Who It's For
The Kraken is a completely different animal: an over-ear headset with an aluminium frame, oval cooling-gel cushions, and indents cut into the pads so people who wear glasses don't get pressure points behind their ears. That last detail tells you who Razer designed this for — someone wearing it for hours at a time, not for a twenty-minute train ride.
The headline feature is the audio. Custom-tuned 50 mm dynamic drivers with a claimed 20 Hz–50 kHz range give you far more driver surface than any in-ear can, and the headset supports software-enabled 7.1 surround sound — but only on Windows 10 64-bit. That's a real limitation worth repeating: if you're on a PS4, a Switch, a Mac or a newer Windows build, you're getting stereo, not surround. The mic is a retractable cardioid boom that's designed to reject background and ambient noise, and the in-line controls give you an analog volume wheel plus a mic mute switch — the mute switch being the thing every headset needs and plenty skip.
The trade-offs are physical. 322 g is heavy next to the 15 g E10C, and over-ear headsets trap heat even with gel-infused cushions. It's also an Amazon Renewed unit with a 90-day limited warranty, so your safety net is shorter than a new-in-box purchase would give you. Who should buy it: PC gamers on Windows 10 64-bit who want surround sound and a boom mic, plus console players who just want a comfortable wired headset. Who should skip it: anyone who needs portability, anyone gaming on a platform that can't enable the surround software, and anyone who'd rather not deal with the renewed-unit caveat.
One more thing worth flagging for accuracy: the Kraken's marketing leans on Razer's position as a top-selling gaming peripherals manufacturer, sourced from third-party retail tracking data. That's a statement about the brand's market size, not about this specific renewed unit or how it will perform for you. Judge it on the 50 mm drivers, the cardioid mic and the cushion design.
• Best for portability → SoundMAGIC E10C. 15 g in a semi-rigid hard case versus a 322 g over-ear frame.
• Best for voice chat and streaming → Amazon Renewed Razer Kraken Gaming. Retractable cardioid boom mic plus an inline mute switch; the E10C has a mic but no boom and no mute.
• Best for positional audio in games → Kraken, with the caveat that 7.1 surround only works via software on Windows 10 64-bit.
• Best for long listening sessions → Kraken on comfort design (cooling gel cushions, glasses indents), though its weight and heat build-up are real; the E10C's lightweight fit wins if you want to forget you're wearing anything.
• Best for commuting and phone calls → SoundMAGIC E10C. Low 16 ohm impedance, tangle-resistant twisted cable, inline volume remote.
• Best for durability of the shell → tie on materials, edge to the E10C for daily abuse. Both use aluminium, but a 15 g in-ear in a hard case survives a backpack better than a large over-ear.
• Best for buyers wary of renewed goods → SoundMAGIC E10C, since the Kraken is a renewed unit covered by a 90-day limited warranty.
• Best if you want everything in one box → SoundMAGIC E10C. Seven pairs of tips, two adapters, a cable clamp and a hard case are included.
If I had to pick one, I'd buy the SoundMAGIC E10C. In my opinion it does the most for the widest range of people: it's light enough to carry every day, easy to drive from a phone, built from aluminium, and it comes with a genuinely generous accessory set that lets you dial in the fit. The Kraken is the better tool if gaming and voice chat are your main job — those 50 mm drivers and the retractable cardioid mic are purpose-built for it, and the cooling gel cushions show real thought about long sessions. But it's heavy, it's platform-limited for surround, and it's a renewed unit with a 90-day warranty. For most readers, the E10C is the safer, more versatile call.
It works for casual gaming — it's wired, low impedance and isolates noise well — but it has no surround processing and no boom mic, so it's a music-and-calls earphone first, not a competitive gaming tool.
No. The surround sound is software-enabled and only available on Windows 10 64-bit. On PS4, Switch and other platforms you get standard stereo over the 3.5 mm jack.
Both rely on passive sound isolation, but they do it differently. The E10C seals inside your ear canal with silicone tips; the Kraken covers your whole ear with gel-infused cushions. In-ears generally block more consistent low-level noise, while over-ears block less but feel less intrusive.
It ships as an Amazon Renewed product with a 90-day limited warranty, which is shorter than what you'd typically get on a brand-new headset. That's the main thing to weigh if you're comparing it against the E10C.
