Product information

Description

The TerraTec HA-1 headphone amplifier is a compact portable amplifier designed to increase audio output and improve listening detail for a wide range of headphones. Delivering a peak power of 0.06 W per channel and a signal-to-noise ratio of 95 dB, the unit supports headphone impedances from 16 to 300 Ω and connects via a 3.5 mm jack. Powered by USB and offering up to 150 hours of battery life under typical conditions, the HA-1 is engineered for mobile use and desktop convenience in a small housing measuring 53 mm × 10.7 mm × 111.5 mm.

Advantages

The HA-1 combines a compact form factor with sufficient output for both low- and mid-impedance headphones while maintaining a high signal-to-noise ratio for cleaner audio. USB power eliminates the need for dedicated power adapters and the long battery life enables extended sessions without frequent recharging. The universal 3.5 mm connector ensures compatibility with most portable audio sources and headphones.

Suitable for

  • Mobile listening with smartphones, tablets and laptops
  • Improving volume and dynamics for in-ear monitors and on-ear headphones
  • Portable desktop use with compact audio setups
  • Travel and commuting where long battery life is required

Key specifications

  • Peak output power: 0.06 W per channel
  • Signal-to-noise ratio: 95 dB
  • Supported headphone impedance: 16–300 Ω
  • Output connector: 3.5 mm jack
  • Power input: USB
  • Battery life: up to 150 hours (typical)
  • Dimensions (W × D × H): 53 mm × 10.7 mm × 111.5 mm

How to use

Connect the HA-1 to a compatible audio source using the 3.5 mm input and attach your headphones to the 3.5 mm output. Provide power to the device via a USB connection to a power bank, computer or USB charger. Adjust the volume on the source device and, if available, on the HA-1 to achieve the desired listening level. For optimal sound quality, allow a short warm-up period after powering on and avoid driving the amplifier into distortion at high volume settings.

Usage recommendations

Use the TerraTec HA-1 with headphones in the supported impedance range (16–300 Ω) and connect to stable USB power sources for reliable battery charging. To preserve battery life, disconnect power when not in use and store the amplifier in a dry, dust-free environment. When pairing with sensitive in-ear monitors, start at low volume and increase gradually to prevent hearing damage and to avoid clipping.
