#19 Donner EM1: $39.99 Amazon eBay
Pros: It is a compact, inexpensive battery powered amp rated for about 12 hours per charge. Its XLR and 6.35 mm TRS combo input accepts a feed from a mixer or interface, and a rated 125 mW into 32 ohms is enough to drive most headphones.
Cons: Audio Science Review measured a SINAD of only 68 dB, a level where noise and distortion become a real audible weakness, especially with sensitive in-ears. There is only a single 3.5 mm output with no balanced option. The Topping A50 III costs more but rates far higher and measured transparent at 121 dB.
