Short answer: the Topping M62. It ranks #1 of 17 audio interfaces by measured performance, rated 4.4/5, at $249. The Topping E2x2 ranks #2, rated 4.3/5, at $159, $90 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Topping M62: Audio Science Review measured 113 dB SINAD, so playback is clean for nearly all listening, and the maker rates the headphone output at 500 mW into 32 ohms, enough for most headphones including many planar magnetic models. The tradeoff: There are no balanced monitor outputs, and the only headphone jack is a 3.5 mm socket, so studio monitors and 6.35 mm plugs need adapters.
What the Topping E2x2 does well: Audio Science Review measured 110 dB SINAD, clean for nearly all listening, and the maker rates the headphone output at 580 mW into 32 ohms, enough for most planar magnetic headphones. Watch for: Its playback converter measures a little behind the Topping M62 and the MOTU M series, and Audio Science Review judged the DAC good rather than exceptional.
Buy the Topping M62. It is rated higher, and the $90 you would save on the Topping E2x2 does not close the gap.

Pros: Audio Science Review measured 113 dB SINAD, so playback is clean for nearly all listening, and the maker rates the headphone output at 500 mW into 32 ohms, enough for most headphones including many planar magnetic models. It runs on a battery and takes USB-C, Bluetooth, two 6.35 mm inputs, a 3.5 mm mic and an AUX input, with parametric EQ on each input and a 10-band output EQ. It rates higher than the MOTU M4 while costing less.
Cons: There are no balanced monitor outputs, and the only headphone jack is a 3.5 mm socket, so studio monitors and 6.35 mm plugs need adapters. The Topping E2x2 offers XLR outputs and similar measured cleanliness for less.

Topping E2x2: $159.00 Amazon $159.00 eBay
Pros: Audio Science Review measured 110 dB SINAD, clean for nearly all listening, and the maker rates the headphone output at 580 mW into 32 ohms, enough for most planar magnetic headphones. Audio Science Review also found its recording converter and headphone amplifier performed very well, and it has XLR combo mic inputs with phantom power, balanced XLR outputs and analog volume knobs. It rates higher than the MOTU M2 for less.
Cons: Its playback converter measures a little behind the Topping M62 and the MOTU M series, and Audio Science Review judged the DAC good rather than exceptional. There is no battery or Bluetooth input, so it stays tethered to a computer.
