Why a 'Dongle DAC' is the Ultimate Sound Upgrade for Your Smartphone
Is Your Expensive Headgear Reaching Its Full Potential?
Have you ever been disappointed after plugging your premium earphones or headphones into your smartphone, only to find the sound quality wasn't the breathtaking 'wow' you expected? The issue isn't with your headphones—it's most likely with your smartphone. The internal audio chip (DAC) inside your phone is designed to be small and power-efficient, meaning it lacks the necessary power to drive high-impedance devices or process the subtle nuances of high-resolution audio files. It's like putting regular gas in a high-performance sports car engine. The simplest and most definitive solution to upgrade your sound quality is the 'Dongle DAC'.
What Exactly is a Dongle DAC?
While a Dongle originally referred to any small USB stick used to add features to a device, in the audio world, it specifically means a portable Digital-to-Analog Converter (DAC) and headphone amplifier. When you connect a dongle to your smartphone or PC via the USB-C or Lightning port, it bypasses the internal audio chip and performs two core functions:
- Cleaner Signal Conversion (DAC): The dongle converts the digital data from your phone into an analog signal we can hear. The high-performance DAC chip inside the dongle effectively eliminates noise and cleanly brings out the most delicate details in the music.
- Sufficient Power Supply (Amplifier): It amplifies the converted analog signal to provide the strong, clear power that your earphones or headphones need to perform optimally. When using high-end gear, you will immediately notice the volume increase and a tighter, more impactful bass.
TheHeard's 3 Criteria for Choosing a Dongle DAC (A Buyer's Guide)
The most expensive product isn't always the best. To choose a dongle that perfectly suits your listening environment and equipment, consider these three factors:
1. High-Resolution Audio Support
You must check the maximum resolution the dongle supports (e.g., DSD, MQA, PCM). If you mainly listen to FLAC or lossless audio, ensure it supports 32bit/384kHz PCM or higher. Every dongle curated by TheHeard possesses outstanding audio processing power, ensuring high-resolution audio files are played back without loss.
2. Driving Power (Output)
Check the dongle's output power (mW). If you use high-impedance headphones (e.g., 300Ω or more), a high-output dongle is essential. While a casual In-Ear Monitor (IEM) user may find 100mW to 200mW sufficient, those using our curated planar magnetic earphones and similar high-performance gear must opt for a model with higher output to fully realize the sound potential.
3. Connection Port (Compatibility)
Confirm whether the dongle uses a built-in connector or requires a separate cable for your smartphone (USB-C or Lightning). TheHeard provides high-quality, dedicated cables with its dongles to ensure perfect compatibility with a wide range of devices.
