Cubilux USB-C to 3.5mm Headphone Adapter 96kHz/24bit DAC

The Cubilux USB C Headphone Adapter converts a USB‑C or Thunderbolt port into a high‑quality 3.5 mm headphone jack using a 96 kHz/24‑bit DAC for clearer, fuller audio and mic support.

Designed for modern phones, tablets and laptops that lack a legacy audio port, this compact dongle restores wired headphone connectivity while improving sound fidelity compared with passive adapters. It includes an internal digital‑to‑analog converter (DAC) and analog‑to‑digital converter (ADC) so your wired headphones and inline remotes work reliably for music, calls and recordings. The adapter is compatible with many USB‑C devices, including the latest iPhone 17/16/15 Pro Max models when used with USB‑C iPhones, plus iPad Pro, iPad Air, Galaxy and Pixel devices.

How does this adapter improve my sound versus a passive cable?

Unlike a simple passive plug, the Cubilux adapter contains its own DAC and ADC, which process digital audio in the adapter rather than relying on the device’s internal audio hardware. That reduces electrical noise and distortion while preserving dynamic range and clarity.

• Dedicated 96 kHz/24‑bit DAC for high‑resolution playback
• Ultra‑low distortion and reduced background noise
• ADC records at up to 48 kHz/16‑bit for clearer voice capture
• Works with both stereo headphones and headsets with mic

Will my headset controls and microphone still work?

Yes. The Cubilux dongle supports inline remote control and microphone signals, so play/pause, track skip, volume adjustments and voice calls are preserved with compatible headsets. It translates the headset’s analog control signals into the device interface, enabling seamless use without software tweaks.

• Supports inline remote buttons for playback and volume
• Built‑in ADC captures 48 kHz/16‑bit microphone input
• No app or driver required for standard functions on most devices
• Works with wired earphones, headsets, and portable speakers

Which devices is this adapter compatible with?

The adapter is built for broad USB‑C and Thunderbolt support across phones, tablets and laptops. It lists compatibility with popular models but is also suitable for many other USB‑C devices that support external DACs and audio accessories.

• iPhone 17/16/15 Pro Max (USB‑C models) and compatible iPad models
• iPad Pro 13/12.9/11, iPad Air 13/11, and smaller iPad models
• Galaxy S25/S24/S23, Z Fold/Flip, Galaxy Tab S11/S10/S9/S8
• Google Pixel 10/9/8/7 and Thunderbolt‑capable laptops

How portable and durable is the Cubilux dongle for everyday use?

This adapter is compact and travel‑friendly, with a short reinforced cable and a sturdy connector housing to withstand daily plugging and unplugging. Its lightweight form fits easily in a pocket or bag, and the design protects the internal DAC while delivering reliable connections during commutes, flights, or remote work.

• Small footprint and lightweight for pocket and bag storage
• Reinforced strain relief to resist cable wear
• Plug‑and‑play: no additional power or drivers needed for most devices
• Works with both USB‑C and Thunderbolt 3/4 ports

Who is this for: The Cubilux USB C Headphone Adapter is ideal for anyone who owns a USB‑C or Thunderbolt device and prefers wired headphones for listening or calls — audiophiles who want better-than-basic audio from streaming and files, professionals recording clearer voice, travelers who need a reliable wired option, and owners of newer iPhone and iPad models that no longer include a 3.5 mm jack. If you use inline controls or a headset microphone and want a compact, plug‑and‑play solution that improves sound over passive adapters, this dongle provides a simple upgrade.
