The HIFIMAN HE400i’s are quite a strange animal. Comfort wise, they’re excellent, although the pads will flatten out over time. Build quality is also very rugged and sturdy, and I love the rotating ear cups. The design of the headband is similar to that of the AKG line. It’s a sort of hammock for your head homie! It really works well. The ear-pads are also just a tad small, I agree with Z reviews; I wish they were a little bigger and more oval shaped. It’s kind of nitpicking though.
Sound wise is where it gets interesting for me. I love the crisp attention to detail that these cans provide, and unlike the Audeze LCD3, I don’t feel like it’s laborious or exhausting. There’s enough clarity to really make you stop and analyze the music in a pleasant way.
What really stood out to me was the Timbre of the instruments. What is Timbre? It’s like I discovered this newfound appreciation for how an instrument or a band is truly supposed to sound. Here’s the best way I can describe what I experienced:
- Crisp detail, clarity. Extremely accurate sound representation.
- Great mid-range. Extremely intimate and realistic.
- Phenomenal instrument separation and precision.
- Great Timbre.
- Articulate bass, but not over done.
- Good Soundstage. It’s not going to blow you away though. Like the HD 600’s, you will occasionally pause the song to make sure no ones in your house. Lol. What is Soundstage?
- Nice packaging.
- Smooth, well extended treble with a bit of sparkle.
- They can get a tad sibilant at times. What does Sibilant mean?
They do pretty well without an amp coming it at 35 Ohms impedance (What is Headphone Impedance?), but I would definitely pair these babies up with one to get the best sound. How to choose a headphone amp!
I personally used them with the magnificent Schiit Magni/Modi combo. See my Magni 2 vs. Magni 2 Uber comparison!!
Who these headphones benefit?
These headphones will sound good with most any genre. I find them to be fantastic with Rock predominantly.
- New Age
- Rock (Classic & Modern)
Intimate and warm, while still somehow retaining a sense of articulation, detail, and clarity. Crystal clear sounding mid-range that can be very revealing at times. Comfortable and durable. Nice bass extension and a treble that sparkles. Can be sibilant at times.
I really love the HE400i’s, but I like the 600’s just a hare better. Why? Because the HD600’s mid-range is more resolving, and I prefer a cleaner sound as opposed to a warmer one. By contrast, the 400i doesn’t sound quite as clear or refined when stacked against the 600. Also, the HD600 represents a true A+ price to performance ratio, and still remains a Gold Standard to this day.
