How to test you earphones with music

As for the sound quality you care about, Jabra Elite Sport is equipped with wireless bluetooth headphone with transparent high frequency, moderate and low frequency, suitable for dynamic music.As far as my actual listening sense is concerned, the high pitch resolution of this earphone is still good, while the middle and low pitch sound are relatively thin. However, for many fitness enthusiasts, they must first improve their equipment if they want to do a good job.Therefore, no matter in inspection or evaluation, we all need to use other tools to understand more clear data, which cannot be accurately determined by our eyes and feelings alone.First, choose the most important tool for your evaluation -- earplugs or earphones (in the following article, all earplugs or earphones are called earphones).A good earphone can directly reflect the quality of MP3 sound.Speaking of headphones, I can't help but grumble.Because the author in the long time observation, found that some relatively sad phenomenon: at least 70% of MP3 walkman users have been using the original headphones.And these original headphones, basically the sound quality is not worth mentioning, even if the deep sea sal MX300, the quality is not much better.Make again good MP3 also hero no use.Does this phenomenon indicate that our national music appreciation ability is declining?Or is music expressive?The author suggests, while buying MP3 walkman, also should consider to choose a pair of excellent earphone, such collocation MP3 ability gets better acoustics.The author usually USES a lot of headphones for sound testing, including SONY mdr-e888, SONY mdr-e575, SONY mdr-e565, AIWA hp-x705, AIWA V743, STAR 001A, etc., but the most commonly used ones are delicate mdr-e888, highly analytical 001A and balanced X705.Listen to some "chicken blood" music demand, or there is no problem.
