Is there a big difference between HD5 15 and HD555? Please tell me more about prawns that I have heard of. I usually watch movies, rock, classical and popular. I want to buy one recently.

These two models are open, not soundproof.

Speaking of differences, when I first auditioned, I thought 555 was good anyway.

But you mentioned going to the movies, and I recommend 555, because I used to use 555.

Its positioning is omnivorous, especially in movies, which is more suitable for you than other similar models.

When it comes to cost performance, I understand it this way: performance or price. When headphones reach this level, there will basically be no low price and high quality. Most of them are high-priced and the sound quality is better. As for the effect, the most reasonable thing is to actually listen. After all, listening habits and preferences are different.
