{"product_id":"aune-ac55","title":"Aune AC55","description":"\u003cp\u003eThe Aune AC55 is the reference model in Aune's clip-on line, built to prove that an open-ear headphone can deliver genuine audiophile depth and dynamics. It keeps the weightless, headband-free comfort of the clip-on format while pushing driver engineering considerably further.\u003c\/p\u003e\u003cp\u003eReviewers have singled out the AC55 for bass depth and staging that rival much larger open headphones, from a design that weighs just 35g per side.\u003c\/p\u003e\u003ch3\u003eType and Technology\u003c\/h3\u003e\u003cp\u003eA 40mm dynamic open driver uses a rigidity-enhanced W-shaped bio-fiber composite diaphragm with a thermally stabilized layer, giving around 70 percent more effective vibration area than typical clip-on drivers. A custom ultra-elastic long-excursion surround enables sub-bass extension that is unusual for open clip-ons, driven by a symmetric motor system optimized for long excursion. Impedance is 30 ohms with 112dB sensitivity.\u003c\/p\u003e\u003ch3\u003eSound Character\u003c\/h3\u003e\u003cp\u003eReference-oriented tuning with real sub-bass reach, natural timbre and a wide, open stage. The unsealed design keeps the presentation effortless and fatigue-free while dynamics stay punchy well beyond what the form factor suggests.\u003c\/p\u003e\u003ch3\u003eBuild and Comfort\u003c\/h3\u003e\u003cp\u003eSemi-memory alloy ear hooks distribute pressure evenly for stable, all-day wear at 35g per earpiece. The 1.25m high-purity OFC Litz braided cable is detachable and ships with interchangeable 3.5mm single-ended and 4.4mm balanced plugs.\u003c\/p\u003e\u003ch3\u003eBest For\u003c\/h3\u003e\u003cp\u003eAudiophiles who want open-ear comfort without giving up reference dynamics, and anyone stepping up from the Aune AC45.
