Rich micro-dynamic NOCS NS900 LIVE earmuff headphones

Unpacking the box, the first thought given to me by NS900 LIVE (hereinafter referred to as NS900) is "Wow good exquisite headphones". When you put it in your hand, you will find that there are many design details in the minimalist style. The brand of this headset is called NOCS. It is a company from Sweden. While pursuing quality and durability, it adheres to the principle of minimal design.

We take a closer look at the NOCS's highest-order earmuff headphones. The first thing to notice is that the NS900 uses stainless steel foil as a bracket that runs through the entire earphone. The surface has black hairline treatment, which is not easy to contaminate fingerprints and has a matting effect. The part worn by the original factory is made of elastic rubber material (there is a bit of Q bomb when pressed hard). The stainless steel bracket is clamped from the upper and lower ends, and then the hexagonal screw is firmly fixed. The tightness is very good, although it is not a common leather. / Flannel material, it is quite comfortable to wear.

In the earphone telescopic adjustment design, the original factory dug a hollow track at both ends of the stainless steel bracket. The first advantage is that the NS900 has a sense of perspective and looks lighter. Then the earmuff can slide freely according to the track. After the proper position, the silver metal round ingot can be screwed and fixed. This metal round ingot is also the visual highlight of the whole earphone.

Another feature of the NS900 is the detachable design, in which the earphone cord can be separated, and the wire connecting the left and right ears above the earmuff is also detachable. After removing the silver metal round ingot, the entire earmuff can be removed (disassembled). Please pay attention to small parts falling.) Where are the benefits? In the future, no matter which part of the headphones is damaged, it is good to remove the parts and not have to throw them away! For action listening or DJ work, these need to use big moves. For the ethnic group, this design is equivalent to extending the life of the headset, which is similar to the Sennheiser HD25 of the year.

Since the wire can be disassembled, NOCS also comes with three earphone cords. In addition to the long spiral wire for general household/DJ, there are two shorter flat wires that support Apple's iOS system and Android system. You don't have to worry about changing your phone. In order to increase the stability of the wire connection, there is a rotary locking design where the terminal is connected to the earmuff. Please pay special attention to this. If it is not properly locked, it will affect the sound quality.

In the specification part, the NS900 uses a full-range single-body with a diameter of 40mm. The surface of the diaphragm is coated with titanium, which helps to increase the rigidity of the diaphragm. The original marking efficiency is 110dB and the impedance is 32 ohms. It seems that it is not difficult to push, so At the beginning, I first used the MacBook Air to output the direct drive NS900. The volume is adjusted to about one-half. I already have enough sound pressure. Because of the NS900's On-Ear design, the ear pads will directly squeeze the ears. Fortunately, the ear pad is covered with a soft leather material, which is comfortable to wear and has a high degree of closeness. The earmuffs are sealed and the sound insulation effect is good, even if the environment is noisy.
