AIR

Air: The "Forever" Wireless Hub

In a market flooded with disposable Bluetooth dongles, the Aroma Audio Air stands apart as a sustainable, desktop-class wireless solution. It solves the two biggest problems of portable audio: battery degradation and sonic stagnation. By utilizing a replaceable 18650 battery system and a socketed Op-Amp motherboard, the Air is designed to be the last Bluetooth receiver you will ever need.

Desktop-Class Architecture

The Air is not a toy; it is a miniaturized desktop system.

• The Brain (DAC): We utilize the ESS Sabre ES9038Q2M, a reference-class chip known for its hyper-detailed retrieval and wide dynamic range (124dB SNR).
• The Muscle (Amp): Unlike standard dongles that struggle with high-impedance loads, the Air's balanced circuit is optimized for voltage swing, delivering 400mW @ 300Ω, making it capable of driving demanding full-size headphones (like the Sennheiser HD600 series) with authority.

The Tuner’s Playground

Why settle for one sound? The Air features a Quick-Swap Op-Amp Socket, allowing you to physically change the Operational Amplifier chip to alter the sound signature.

• Stock Configuration: Tuned for transparency and speed.
• Customization: Swap in a Burson or Muses chip (sold separately) to add warmth, tube-like harmonics, or analytical precision.

Infinite Power Cycle

The internal power source is a standard 18650 Li-ion battery (3400mAh).

• The Benefit: When the battery degrades after years of use, you don't throw the device away—you simply pop in a new $10 battery.
• On-the-Go: Carry a spare battery for instant 0-100% recharge during long flights or remote listening sessions.

Connectivity & Filters

• Inputs: Bluetooth 5.0 (LDAC, aptX-HD, aptX-LL, AAC, SBC) or USB-C DAC mode.
• Outputs: 4.4mm Balanced, 2.5mm Balanced, and 3.5mm Single-Ended.
• Digital Filters: 8 user-selectable filters (via power button) to fine-tune the transient response and roll-off.

Air：無線音頻的「永續」樞紐

在充斥著「一次性」藍牙產品的市場中，Aroma Audio Air 以其可持續性和桌面級架構獨樹一幟。它解決了便攜音頻的兩大痛點：電池老化與聲音固化。通過採用可更換 18650 電池系統和可插拔運放（Op-Amp）母座，Air 被設計為您可以長期擁有的終極無線伴侶。

桌面級架構 (Desktop-Class Architecture)

Air 不是普通的藍牙接收器，而是一個微縮的台式系統。

• 大腦 (DAC)： 搭載 ESS Sabre ES9038Q2M 參考級晶片，以其超高的解析力和寬廣的動態範圍 (124dB SNR) 著稱。
• 推力 (Amp)： 不同於在驅動高阻抗耳機時乏力的普通「小尾巴」，Air 的平衡電路專為高電壓擺幅優化，在 300Ω 時可輸出 400mW，足以從容驅動如 Sennheiser HD600 等高阻大耳牛。

調音師的遊樂場

為何滿足於一種聲音？Air 配備了快拆式運放插座，允許您通過物理更換運放晶片（Op-Amp）來改變聲音特質。

• 原廠配置： 專為通透度與速度感調校。\
• 客製化： 您可以自行換入 Burson 或 Muses 等發燒運放（需另購），為聲音增添溫暖的膽味或極致的分析力。

無限續航循環

內部電源採用標準的 18650 鋰離子電池 (3400mAh)。

• 優勢： 當電池經年使用老化後，您無需丟棄設備，只需更換一顆標準的 18650 電池即可滿血復活。
• 戶外應用： 在長途飛行或旅行中，攜帶備用電池即可實現「瞬間滿電」，告別充電焦慮。

連接與濾波

• 輸入： 藍牙 5.0 (支援 LDAC, aptX-HD, aptX-LL, AAC, SBC) 或 USB-C DAC 模式。
• 輸出： 4.4mm 平衡, 2.5mm 平衡, 以及 3.5mm 單端。
• 數位濾波： 內建 8 種數位濾波模式（通過電源鍵切換），可微調瞬態響應與高頻滾降特性。
