Electronic music in particular is satisfying, with Rock, Emo, Pop and Dubstep sounding really nice too.

Wired yet far from tangled, great sound quality, good looks, and a comfy fit all add up to make these cover all the key bases well. For example, “ Hotel California (Live on MTV)”, is presented with fairly clean and articulate guitars, even if a little warm. There’s also a pleasing sense of space, scale and expansiveness to the soundstage the SV023 presents, with good space for instruments and vocals to co-exist.

They sound great plugged right into a laptop and because they are very efficient, that is how I would recommend. The midrange of the Sivga Robin is really clean, detailed and wide, but recessed considerably behind the bass, and behind the treble.It has a low impedance and high-sensitivity rating that allows it to be powered straight out of your smartphone.

The sound has that dark cast inherited from the upper bass, but if you listen to some Apashe and his Witch song, the sub-bass truly rattles all around the stage, with the voices being very clearly positioned in front of the listener, and the background drums being all over the place, scattered, just as intended. Overall, Robin is better in terms of bass, dynamics, and soundstage width, but k371 has the better midrange, tonal balance, and resolution. Durable Connections The headphone’s drivers are protected by a newly designed casing for enhanced durability and protection from the elements. The earpads are detachable easily, and you can replace them, plus the 50mm driver with 32 OHM Impedance and 105dB SPL is no problem even for FiiO BTR5 MK2, or Shanling UA2. Inside the simple box you get the headphones, a cable of matching color, an adapter and carrying pouch.

Sivga promises the sweet spot of balanced, natural and accurate sound, and that's mostly come to fruition. This is very apparent with the 20% of music that it doesn't work well with as the dip in the midrange just further emphasizes the incoherency. Something I’d like to clear up straight away is that the design differs between the two available colors. Besides the 50mm driver sounding tempting, a claimed frequency response of 20Hz to 20kHz is even more appealing, though not out of the ordinary for headphones made for budding audiophiles. If the company took more time to fine-tune the drivers and implement horizontal rotation into the ear-cups, this could've been a very neat release.

This is not a huge amount of content, nor is it really a premium presentation, but it is enough to make the headphones usable straight from the box and, let's face it, for a set of headphones that retails for less than 170€, I really can’t bring myself to complain. They feel congested and overlapping sometimes but the layering does give a space around them which is this guy’s saving grace.The uniquely developed polycarbonate film and the independently developed diaphragm structure not only solve the shortcomings of the diaphragm being easily deformed, but also ensure the transient and detail of sound restoration.
