The new X1 2nd gen now boasts Bluetooth 4.0 wireless tech and a more responsive touch wheel user-interface into a handsome design. Build quality feels more robust. It’s pretty tiny, just 2.2 by 3.6 by 0.5 inch (55x97x12mm), and lightweight, a mere 3.6 ounces (102 grams), but the beautifully machined aluminum body.
The second-gen X1 supports up to 256GB Micro SD cards, but alas, there’s no built-in memory. The 1,800mAh lithium-polymer battery provides up to 12 hours of playback time with APE, FLAC, ALAC, WAV, WMA, AAC, and MP3 files, with up to 32-bit/192 kHz resolution.
