Rose BR7 7 Balanced Armature Driver

General Information

Description:

• Warm and elegant, born for sound
• Perfect ergonomic design
• By sampling and comparing 24 Asian ear canal 3D data, it has repeatedly modified the sampling up to more than 10 times, collected wearing feedback, and finally achieved go deep into ear canal and reduce energy attenuation, and it is perfectly fit and comfortable to wear.
• Advanced shell manufacturing process, professional shell manufacturing team
• Rose technology chooses to collaborate with a listed print service company, relying on its strong technical capital advantage, using a PMMA material shell made from a German 3 million level precision industrial printer
• The most advanced German 3D printing technology, using PMMA acrylic fiber and 0.01mm precision printing, no accumulation of stripes, transparent. Compared with traditional resin materials, high temperature resistance, heat shrinkability resistance and impact resistance is greatly improved
• Good voice, stemming from superb tuning
• 4 sub-frequency configuration: 1 super bass frequency, 2 mid frequency, 2mid high frequency, 2 super-high frequency.
• 4-way catheter, no interference, fish-mouth sound outlet, so that the sound for a whole
• Good voice is from leading drive unit hardware
• From international leading balanced armature driver supplier: Denmark SONION and American Knowles
• High-end hardware ensures excellent quality
• Non-damped ultra-short high-frequency balanced armature sound system
• Ultra-short high frequency sounding distance and straight through non-damped design, keep high frequency details at a maximum, suppress attenuation.
• Dual Knowles swtk super high-frequency balanced armature, high resolution, low distortion. Dual guarantees bring excellent high-frequency experience which with rich sense of air.
• [Super low+] technology
• Rose technology modifies the low-frequency balanced armature structure by adjusting the frequency dividing circuit so that the br7's low-frequency dive strengthens and no longer need to tolerate the traditional balanced armature tone of the knocking iron.
• Good voice, from each original details
• With ELNA capacitor which is designed for audio, use OFC oxygen-free copper feet, very low distortion (third harmonic distortion -120dB), natural silk fiber media, high-quality sound, play the gentle neutrality of silky, increase the thick sense of low frequency, reduce the rough sound quality of the high-pass section that has peak feeling and the middle-frequency section.
• Sound: Fast and powerful, suitable for modern music. The bass is a bit thin, but it does not feel less low frequency. The sound feels smooth, and the sound field is relatively large.
• Using global electronic components leading brand tdk audio carbon film resistors
