Crassirostris is a collaboration model earphone of Jaben and Oriolus, and is a product planned by JABEN CHINA.
The name seems to be a bird called Tanagers, and the box picture also has a bird picture. I think it's probably a bird that sings with a beautiful voice.
The price is open, and the actual sale is planned to be around 122,000 yen excluding tax. The configuration of Crassirostris is a hybrid configuration of BA3 + D1 and basically the same series as Oriolus Reborn, but the BA part (tweeter) is a different model number. This earphone is not monitor-like, but basically tuned so that you can enjoy listening to beautiful sounds. It feels like a derivative model of Oriolus Reborn. The shell is made with 3D printing. The sensitivity is 115dB / mW, the impedance is 21 ohms, the frequency response is 10Hz-40kHz, and the box has a high resolution sticker. The wire material of the cable is copper, silver, silver-plated copper wire. The cable terminal is 3.5 mm. Includes silicone earpiece, foam and double flange (M). The shell is transparent and you can see the driver placement. There is a vent hole directly in the shell space. It looks like there is some filter in the vent hole. The space inside the shell will be a chamber for the dynamic driver. Also, the nozzle part is made wide. The plug is so tight that it feels like a maniac product. The cable is a fairly elaborate standard cable, which is supple and not bad to handle.
Although it is a large shell, it is relatively comfortable to wear, and the silicone earpieces are particularly well made and adhere to each other. It feels like it's sticking to you. I think the sound insulation is quite good. The efficiency is high and it is easy to ring. First, try the A & K AK380, which has a neutral and easy-to-listen sound. It's just tuned musically, so the sound is easy to understand, it has a low center of gravity, the weight of the bass, and the sound spreads great. The AK380 and Crassirostris mid-high range is sharp and you can hear the sound of plucking the guitar clearly. The low range is quite exaggerated and has plenty of volume. It seems to be a hybrid configuration, and you can feel the weight in the sound. From this area as well, the direction of listening while enjoying the sound rather than listening like a monitor is conveyed. However, although the low range is strong, I think the vocals can be heard fairly clearly.The frequency response is quite exaggerated, but the tone itself is rather neutral rather than too warm. I think that this area is also related to the cable characteristics. Another point of Crassirostris is that the sound spreads well. It's a relatively wide person on the left and right. There is also a sense of depth. There is plenty of bass and the sound spreads well, so the scale feeling in an orchestra is also good. The individuality of the sound seems to match the A & K SP1000CP, so when I changed the player, it felt like a big hit. This combination is the best.
With the improved sound performance from AK380 to SP1000CP, this also has the meaning of drawing out the power of Crassirostris. Crassirostris is not just a fun type earphone with resolution, but it seems to have high potential. This is probably the result of the original Oriolus Reborn performance. The SP1000CP and Crassirostris high frequencies also feel more beautiful when listened to with the SP1000CP. Combined with the good sound field, in electronica, the sound of a bell or an electronic sound similar to it echoes in my head, and it sounds like a beautiful mid-high range is raised in combination with the rich low range. It seems that you will be drawn into the world of music. In female vocal jazz, whispering vocals are also reproduced in detail. For example, in the classic "Spanish Harlem", the bass of the back sounds a little big, but the vocals are beautiful and the voice quality is also audible. With anime songs, the back performance sounds a little loud, but you can still enjoy it dynamically. In this vocal-based genre, it feels like a reproduction for people who want to enjoy not only vocals but also playing. I think rock is the most suitable genre because it is particularly powerful and has high low-frequency reproduction.
There are percussion and drum punches, and the banging sound is powerful and pleasant. The entanglement of the bass guitar and drums that folds up is the best. You can enjoy the powerful and dynamic world of sound. I don't think there are any earphones that can reproduce the comfort of a bass guitar or bass drum so far. You can feel comfortable by hitting the drums and percussion repeatedly, and I think that your feelings will rise considerably.
For example, in the case of metal, you can enjoy each of the songs such as beautiful female vocals that can be heard with a low death growl background, and you can comfortably hear the destructive drums called Dosdondon.
The compatibility with Oriolus 1795 is also good. If you want to listen to it on your smartphone and BT, it wouldn't be interesting without the sound quality of Oriolus 1795.
After all the sound spreads well and you can enjoy the power of the bass. The tone is beautifully reproduced, and the sound and fineness are quite high. Perhaps this combination will allow you to immerse yourself in the music without the feeling of listening to Bluetooth. Oriolus 1795 can also take advantage of crassirostris in that it has a sense of speed for a BT receiver. Oriolus 1795 and Crassirostris Earphones for those who want to enjoy music in the front row with a sense of dynamism rather than analytical. It is also suitable for powerful and high-performance players because it has high basic performance based on Oriolus Reborn. Recommended for those who want to enjoy music and those who have a powerful high-end player.
