This site is the first home made good headphones - Austrian sharp KC08 Nirvana headphones unpacking

Written in the front: this article is mainly out of the box

In addition, I really feel that headphones and playback devices are pits.........


Most of my previous needs for the headset is to listen to a ring on the line, in the popular MP3 is generally standard headphones, mobile phones after listening to popular songs is the standard mobile phone headset (that is still more kind of mobile phone manufacturers ...) Afterwards, when Nokia fell down, I married an AKG K44, followed by a Sennheid girl, Boseo Generation, Skullcandy SB2W wireless headphones, and even used the cat ears earphones to wear too tender, but the domestic headset is The first time to start. It's not that I believe it or I'm picky. I really don't know what to choose.........

There are two reasons to choose this: There is a need for a portable headset. Both the buns and the Bose OE are in-ear style. It's inconvenient to carry, for example, to buy a dish or something; don't like an in-ear stopper and want a flat head. This is not easy to find.

Unpack it directly. Many maps, please open WIFI...

This headset is called Nirvana. The outer packaging looks like a black and white color scheme. But in fact, Nirvana’s piece is a sticker and is affixed to the film on the outside of the package. I think the two words are very good, and they are affixed when the picture is taken. The front gap reveals the main body of the KC08 headphones. On the back there are various parameters, designers, manufacturers and other information of the headset. This headset is a 32-ohm impedance headset, I see less, first see the 32-ohm earbuds ...

Open the box on both sides. The headphone horse is revealed in the middle.

Upper and lower floors. In addition to the upper body of the headphone, the upper layer is a standard headphone storage box on the left and the matching headphone sleeve on the right. There is a description of the lower level and another matching headset sets ... ... I thought to give weight initially, and later found two sets of headphones slightly different, in the end will say.

PS: It's not a habit to use a WYSIWYG single-power switch instead of a SLR.... Invincible rabbits are not used to it, but when I look at full-frame images, I'll endure it...

I haven't seen a flat head earplug for a long time. It's amazing. Impression in the previous headset is a lot of holes, this KC08 is ring mounted, this multi-layer arrangement is not what pay attention to it? I don't know much about this...

The earplugs are made of metal and obviously feel heavy when first taken. The metal part behind the earbuds is titanium grey, with OS logo on the side, while the metal-colored part and the resin on the other side form the tail of the plug, wrapping the wire and providing support.

The work of the metal part is delicate, and the "KC08" and "R" above are very fine. I don't know metal processing very well. I just think this shouldn't be cast... CNC out? ?

This headphone is a pure music earphone. There is no Mic, there is no other operation button, when listening to the phone, it is still somewhat inconvenient. The lower half of the wire is wrapped in a textured pattern. The plug is gold. I don't know if it is gold plated. Then the tail of the plug is slightly curved. The diameter is slightly larger and easier to pull out. However, I think this 3.5mm connector is not tight, and it is easy to insert and pull.

Post two pictures

In addition to headphones, accessories are also good.

Standard magnetic storage box, three grooves and projections, snapping on both sides, and magnet adsorption, take the wrong place, really can not open. Magnets are also very powerful. I don't know if there will be any changes in the magnetic field in the headsets that have been there for a long time...

The sponge cover of the earphone can be found carefully. It can be found that one of the two sponges is of equal thickness, while the other is dark, and the position of the pattern is definitely thinner. At the moment, I use this pattern, and I haven't tried another pair of thick ones... Who told me why this is used? In addition to not grinding ears...

This is what it takes to put it all together. Oh, there's a tangled line fitting in the middle of the storage box. I'm worried about the effect of the magnetic field between the two headphones, each time back-to-back.

Simply talk about how this headset sounds.

First wear it, because it is a flat head plug, it is a 16mm unit, I feel my ear hole is a bit small, and the seal is not too strict, unlike the in-ear type can better shield the outside interference, reduce noise, so when the night is still quiet to enjoy alone Better.

Second, the sensory resolution is very good and very delicate. Although he did not see Hi-Res's certification... Although it is a flat headed earplug, the bass is still good, and the tri-band aspect is also biased toward mid-low, and the treble is slightly weaker.

As for how good this headset is...I can hardly describe it. However, for this earphone I participated in the crowdfunding of Shanling M1. I didn't feel that when I listened to Xiao Biao and Bose OE. I think this may be a feeling of getting into the pit...


GPON ONT

GPON (Gigabit-Capable Passive Optical Networks) technology is the latest generation of broadband passive optical integrated access standards based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. It is regarded by most operators as an ideal technology to realize broadband and comprehensive transformation of access network services. GPON was first proposed by the FSAN organization in September 2002. On this basis, ITU-T completed the formulation of ITU-T G.984.1 and G.984.2 in March 2003, and completed G.984.1 and G.984.2 in February and June 2004. 984.3 standardization. Thus finally formed the standard family of GPON.

GPON technology allows operators to provide specific services that their customers need to provide in a targeted manner based on their market potential and specific regulatory environment. GPON technology and equipment are relatively complicated. GPON bears the advantages of multi-service with QoS guarantee and strong OAM capabilities to a large extent at the cost of technology and equipment complexity, which makes the cost of related equipment higher. With the development and large-scale application of GPON technology, the cost of GPON equipment will drop accordingly.
