HIFIMAN HE-R9 封閉式動態耳機

I was skeptical about closed-back headphones until I tried these — the topology diaphragm captures so much detail in the high frequencies that cymbals and strings sound crisp without being harsh. They're also sensitive enough to drive well straight from my phone, which is a nice bonus.

The rare earth magnet really makes a difference in sensitivity — my phone drives these louder than I expected. The topology diaphragm also brings out details in cymbals and strings that I’ve missed on other closed-backs.

I was blown away by how clear the high frequencies sound on these headphones, especially with the topology diaphragm handling complex tracks. The closed-back design also does a great job blocking out noise without feeling too heavy on my head.
