M7 comes with a 3.2-inch touch display (800x480 pixels), a dual-core Samsung Exynos 7270 processor, and a Sabre ESS 9018Q2C DAC chip for speedy conversion of audio.
It also comes with Bluetooth 4.2, with support for aptX-HD, aptX and even Sony’s LDAC format, thus allowing for quality streaming of High Resolution Audio (HRA) files. On that note, the M7 supports playback of APE, WAV, FLAC, AIF, DSD, M4A, WMA, OGG, AAC, ALAC and MP3 files, so it’s safe to say your music library should be comprehensively covered. The M7 is very smartly designed, with just four physical buttons (including the power button) on the player. Volume control is via a scroll wheel on the left of the player, and this is stepped for more accurate control. You can even disable the buttons when the screen is locked, so you won’t accidentally skip tracks when your player runs against something else in your pocket. It's definitely a thoughtful touch as trying to pull the player out of the pocket would often result in tracks being skipped, so the option to disable the buttons for our extended use is most appreciated. On the touchscreen front, we’d say touch navigation is well implemented with this DAP, as it allows you to easily browse through your music collection or go through the settings on the player. There are two global shortcut gestures too – slide your finger up from the bottom left corner of the screen to go back a step. Slide it up from the bottom right, and you jump back to the main page. Simple, but effective. The M7 comes with a USB-C port for faster charging and transfer. This also feeds audio out, so if you have a USB-based headphones set, you can feed it audio directly. There’s also a built-in FM tuner so you can use your headphone’s cable as an antenna to get live radio on the go. This works surprisingly well, though we did wonder if they would be able to offer an antennae accessory that went into the 3.5mm audio jack so you’d be able to continue using your wireless headphones.
