Build Quality

One of the biggest differences between Hifiman Sundara vs 400I is the build quality. The Hifiman Sundara is really rugged and this makes it seem as if it has been designed and made to be ready to withstand usage abuse. Plus it isn’t foldable so there’s a downer for it. 

Hifiman Sundara recently designed comes with a metal-infused frame. This makes it more sturdy and reliable. It can stand a few bumps and nudges while on someone’s head. As a result, you will find the frame to be incredibly tough and solid. It will not break easily, even when pressed or pulled heavily

On the other hand the Hifiman 400I is generally well-built, but it has some weak points which makes the HiFiman Sundara a step ahead of it. It is designed for luxury and looks and less for protection and durability. Unlike the sundara, it does not come with anodized aluminum gimbals, which are sturdy and durable. Making it a step behind in terms of sturdiness and durability.

Bass performance

When it comes to bass performance. The bass performance for the Hifiman Sundara is pretty much neutral and linear. It does not come with that dominating sound on the bass hence may make the music seem flat and boring than it actually is. Though not as dominating as you would want it to be. It still is not soft or flabby. 

The bass is just enough to make enjoyable music without muddling the midrange and treble. Besides that, because of the controlled bass response. You’ll be glad to know that the lower mids are pretty much accurate and detailed. The vocals are also quite clear, crisp and accurate giving you a great music experience still. The treble is energetic and elevated without being overly peaky.

He400I generally sounds great. Which we can prove by the fact that it is rather quite popular in the market. The bass is well-extended, and it is tight and punchy. Unlike the prior set you can actually feel the bass well enough to enjoy the song at its full potential without having to face any disappointment whatsoever. 

The midrange is somewhat warm and really enjoyable. It comes with a treble that is impressively clear, evident, and lively. Sadly when compared to the Hifiman Sundara it tends to be a tad bit muffled especially in the midrange and it is also a bit more sibilant in the treble.
