And 4.4 is a balanced mouth with greater thrust, listening to some magnificent music and having a sound experience of a cinema. Comparison of earphone balance ports of 2.5, 3.5 and 4.4: The balance ports of 2.5, 3.5 and 4.4 are made by different manufacturers, and the sound will definitely be slightly different, but there is no clear label. I found the following information on major websites. A balanced accent of 2.5 will sound more delicate and cleaner. The sound field of the balance port of 3.5 is bigger and the atmosphere will be better. The anti-interference ability of the balance port of 4.4 is much greater than that of the balance port of 3.5. I didn't say the best, I can only say that each has its own advantages.
