Audeze iSINE 10 In‑Ear Planar Magnetic Headphones (Black)

Big, open‑back sound—now in a pocketable in‑ear

If you’ve ever loved the scale and realism of full‑size planars but wished you could take that experience everywhere, the Audeze iSINE 10 delivers. Its 30 mm planar magnetic drivers—paired with Fluxor magnets, Uniforce diaphragms, and Fazor waveguides—unlock an airy, speaker‑like stage, ultra‑low distortion, and bass that reaches confidently into the sub‑bass, all from a lightweight in‑ear form factor. This is the portable, open‑back listening experience audiophiles have been waiting for.

Why Audiophiles Choose This Product

• The sound: expansive, articulate, and alive
  The iSINE 10 projects a remarkably open, holographic stage uncommon in IEMs, with incisive detail through the mids and treble and bass that stays tight and textured. Reviewers consistently highlight its “wonderful spatiality” and convincing imaging that extends beyond the ear.

• The engineering: true planar tech in an in‑ear
  Audeze fits a full 30 mm planar magnetic driver into each earpiece, driven by powerful Fluxor magnets and a ultra‑thin Uniforce diaphragm, guided by Fazor waveguides for smoother phase behavior—technology distilled from Audeze’s reference LCD series. Result: wide bandwidth (10 Hz–50 kHz) and <0.1% THD at 100 dB.

• The practicality: lightweight comfort for long listens
  At just 20 g per pair, the semi‑open shells rest lightly with included ear hooks and tips. You get the breathability and ease of an open‑back design—ideal for extended sessions—while keeping your setup pocket‑friendly. Note: as a semi‑open in‑ear, it leaks some sound and doesn’t isolate like sealed IEMs.

• The compatibility: simple analog, smart digital
  Plug the included 3.5 mm cable into virtually any device, or add Audeze’s optional Cipher Lightning cable for iPhone/iPad to gain a built‑in DAC/amp plus a 10‑band EQ in the Audeze app that stores two presets in the cable. It’s a powerful way to personalize tonality while retaining the iSINE’s technical strengths.

• The difference: a pioneering planar in‑ear
  When the iSINE series debuted, it helped establish the category of full‑range, planar‑magnetic in‑ears—bringing big‑driver dynamics and scale to a mobile‑first format.

Sound Signature and Use Notes

• Signature: Open, spacious presentation with articulate bass, revealing mids, and extended, lively treble. The semi‑open architecture contributes to the wide stage and airy feel.
• Personalization: Many owners enjoy light EQ to taste; with the Cipher cable, Audeze’s app provides two savable 10‑band EQ presets stored in the cable’s memory, making on‑the‑go tuning effortless. Community feedback also points to EQ as a powerful way to refine the iSINE’s balance on non‑iOS sources.
• Comfort: Expect a learning curve with the fit. Use the included ear hooks and tip selection; once settled, the lightweight shells support long listening with minimal pressure.
• Environment: Because the design is semi‑open, use in quiet spaces where sound leakage isn’t a concern.

The Bottom Line

The Audeze iSINE 10 marries true planar‑magnetic scale and refinement with everyday portability. If you crave an open‑back soundstage, fast transient response, and sub‑bass reach without carrying full‑size cans, this legacy in‑ear remains a compelling, research‑backed choice—especially when paired with Audeze’s Cipher cable for simple, precise EQ. It’s an enthusiast‑grade listen that travels.
