If price is not a factor, I recommend the Ioudi I7 as a flash drive. The sound quality is outstanding among flash drives, the style is suitable for light music, and the instrument performance is very good. Of course EQ is also good.

I recommend the Sony A8XX series when listening to vocals. The vocals are very good, but the performance of light music is not as good as the Ioudi I7.

In fact, it is very good to directly connect to the hard drive, and IPC is highly recommended. Apple's machines have almost no sound effects, but the sound quality of IPC is excellent. Although it is relatively dull, the reproduction is very good. Such machines are easy to match with plugs. You can change the style of earplugs you like, plus IPC The reasoning is great, the plug is very easy to replace. If you have the money to buy a second room, it will probably be considered a success in Zhongshao. Generally speaking, it can't be compared with other machines except Kenwood. Of course, the battery life of IPC is very strong. After all, it is so big, so it is easy to plug in a big battery. (But I don’t recommend Apple’s other series, the sound quality is terrible)

The Blue Devil 970 is okay, but it is MP4. I remember it was 300 yuan
