Hi All,
This new flagship from Rose Technics, BR7 seems very very interesting. It seems to be a combination of Knowles & Sonion balanced armature drivers, with a focus on getting great fit and isolation. They seem to have focused a lot on tuning, and use ELNA capacitor as well. Hopefully, this thread will help achieve a more focussed discussion on this very promising IEMs.

Below is the information I could find of them:

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

So, finally I got the Rose BR7 today. Attaching a few pictures of the same. In terms of build quality, look and feel, it seems remarkably similar to the Rose BR5, which similarly had a earplug design that goes pretty deep, and seems to provide good isolation (yet to get the right tips to fit me well though). I like that this time, they have decided not to have the Rose name in the engraving and instead have the logo, which looks better.

I think I will need to spend more time, to get a hold of the sound. Initial impressions of the sound, it seems that tonality wise, it seems to be slightly brighter with a more linear bass, and slightly upper-mids focussed sound. Treble seems to extend quite well. Soundstage is quite impressive, with a good amount of depth and width.

Here are a few pics:

Did you ever end up giving these a listen?

I did. It seems like both BR5 and BR7 share the same common house sound. Rose BR7 can be termed as a more evolved BR5. It has a very resolving mid-range, with a more extended treble (lots of air, is not very sparkly, so shouldn't sound harsh or fatiguing to most ears). In terms of imaging, the soundstage depth is also improved compared to the BR5. I heard mentions that Rose seems to have replicated what the 64Audio "Tia" drivers have done, and call them "Eze" drivers. Maybe that explains the improvement in treble and soundstage, in particular.

In terms of design, I think they have done a terrific job here. These are now my personal favourite, and achieve the best combination of comfort and isolation. It is able to isolate to near Etymotic or custom IEM level (better than massdrop plus, magaosi X3, DM6 etc, all of which now have some kind of universal custom like design), while being super-comfortable.But, keep in mind, that these go pretty deep, so may not be for everyone.

W.r.t tips, I found that Spiral dots helped opened up the mids (also it no longer seems bass-light, maybe has to do with me getting the right fit). Although the bass is not boosted, it does comes up in tracks where it is required with proper slam. Transient response is also improved relative to BR5. So, overall sound signature, I would not state as bright. But, these would be near neutral with slight upper mids focus, which works great for female vocals.

do you have any thoughts comparing this to other chi-fis like the bvgps or fearless?
