Sony's portable MP3 products can be roughly divided into two types: split and all-in-one, the split type generally supports Bluetooth or wire control function, and some also have a back clip, or use it with a sports armband; The all-in-one player integrates the player into the headphones, which can be used in harsh environments such as underwater, but the sound quality will be greatly reduced, Sony calls it a wearable music player, which can be used directly from wearing.

If you have a high pursuit of sound quality in sports, then these two are good choices.

NWZ-A17 supports Hi-Res high-resolution audio sources, supports a variety of lossless formats, and has a delicate sound quality that is difficult to achieve on mobile phones. The battery life is strong, up to 50 hours of normal playback, and 30 hours of Hi-Res audio playback.
