About the OBH-11

The Creek Audio OBH-11 is a miniature headphone amplifier engineered to drive a single pair of headphones with impedances ranging from 30 to 300 ohms. It accepts line level input from sources such as CD players or pre-amplifiers and is not designed to connect to speaker outputs. The unit features a high-quality volume control on the front panel and a 1/4" stereo TRS headphone output jack. It includes a multi-region 24V DC power supply adapter compatible with Europe, UK, and USA plugs, drawing less than 0.5W when idle and operating silently without a fan. The OBH-11 is praised for delivering deep, tight bass, natural vocals, and a clear, airy soundstage, making it a significant upgrade over typical headphone outputs on CD players. It also offers an upgrade path for the power supply to enhance performance further. The amplifier is housed in a sturdy aluminum case with a refined front panel design and weighs approximately 360 grams.
