Neoteck NTK059 Portable Headphone Amplifier vs Fosi Audio PH04 Headphone Amplifier

The Neoteck NTK059 is a single-output portable amp with a rechargeable battery, so it suits one listener moving between phone, laptop and MP3 player. The Fosi Audio PH04 is a four-output desktop amp with separate volume knobs per channel and a 12V wall adapter, built for sharing one source among several headphones. The Neoteck's aluminum body and 16–300 ohm range cover most everyday headphones; the PH04's 80 ohm output impedance and modest 40mW at 100 ohm make it a better fit for easy-to-drive headphones than for high-impedance studio models. Buy the Neoteck for portable one-person listening; buy the PH04 when several people need to hear the same mix.

• Choose the Neoteck if you want one headphone amp you can carry and recharge, and you listen alone from a phone, laptop or player.
• Choose the Fosi Audio PH04 if you need to feed three or four pairs of headphones from one source, each with its own volume knob, at a desk or in a studio.
