"Conclusion

Pros

• Great design emphasizing on comfort and light weight.
• Affordable for planar magnetic headphones
• Impressive lows and mids

Cons

• Suitable to use in private spaces only
• The design is not really attractive for young audiophiles

The HiFiMan HE-400i is among the lowest-priced planar magnetic headphones on the market but it doesn’t disappoint me. I’ve used it for nearly a year and don’t have plan to upgrade anytime soon."
