Check Out The SIVGA P-II Planar Headphones
According to SIVGA: “The technical team had spent more than 3 years on the research & development of ID design, acoustic design, speaker structure and diaphragm material, etc, they spent countless efforts and energy till the headphone was finalized.”
Basic specs for the SIVGA P-II are as follows:
- Transducer size: 97mm*76mm
- Frequency response: 20Hz – 40KHz
- Sensitivity: 98dB
- Impedance: 32 Ohm
The P-II also ships with a cable which is terminated with a 4.4mm Pentaconn connector, but a 4.4-3.5mm adapter is included so that the headphones can still be used with single-ended equipment too. 
SIVGA has also gone into a bit more detail regarding various parts of the P-II.
EARPADS
The headband sheath and earmuffs are high protein leather, very comfortable to wear.. There is enough room in the ear cups so that they do not cause any pressure on the ears and provide a good seal. Both for comfort and sound, this headphone gives you a better experience.
FRAME
The main structure is all metal, stainless steel in an all matte black color theme. Solid and thick, adding some extra weight but also much higher durability. The steel part goes from the upper headband arc down to the round yokes. Two Ear Cups can be rotated up to 90°, convenient for single-side monitor.
AUDIO CABLE
6N single crystal copper wire – relatively soft, tangle resistant and carries no noise. The plug termination is of the new 4.4mm balanced type which is getting more popular with new audio devices. At the same time, equipped with 4.4 to 3.5mm cable, it makes your headphone work with more players.
Pricing
For the most part, headphones using planar magnetic drivers as well as incorporating exotic materials such as wood into their design tend to also come with a higher price-tag. However, in the case of the P-II, SIVGA have managed to offer this headphone for a retail price of just $399. Of course whether that price is fully justified will depend on how it actually sounds as well as the quality of construction, so it’ll be interesting to see what the collective perceptions are once reviews start hitting the web.
