I finally received my C4 last week. Fit is great, I think (these are my first ciems).
The sound is..hmm...different. At home I mostly listen to my Grado SR80 or HF-1. My headphones on the go are Sennheiser IE8.
I have spend so far only a few hours with the C4 but the sound is something that I have to get used to. I am so far not blown away by how they sound. I am trying to explain why.
As I wrote, I am listening a lot to my Grado HF-1. I really like how they sound. They just have the right amount of lows and highs. Also vocals sound great and music generally sounds airy and crisp (but I have no idea, if they are supposed to be neutral).
However, the C4s are supposed to sound neutral. Well, they definitely sound different compared to the HF-1.
The first thing that is striking are the lows. Wow, they are there...a lot. Songs like “Limit to your love” from James Blake rattle my cranial bones. The mids sounds also great. I love listening to Katie Melua or Diana Krall on the C4s. The voices sound very natural and forward.
But the problem is that everything sounds like under a veil. If I switch back to the HF1 the crispness of the music is so evident. Everything sounds just clear.
A lot of course depends on the equipment that is used. At the moment I am listening straight out of my MacBook Air or iPhone without a headphone amp.
My music files are mostly AIFF or 320kbit MP3.
Like I said, I have only spend around 10h with them. Thus, these are only the first impressions, I wanted to share.
I will continue listening to the C4s and I am very curious if I will change my first impressions. Maybe I will adapt to the sound signature (because frankly, I have no idea how neutral headphones are supposed to sound
).
