Been using it for a week and I personally liked the what you call "dark" sound it produce, In my case it makes the music a bit deeper.
Just in case anyone is wondering, this is how XiaoMi Hybrid's sibling look like in measurement: 1MORE Multi-Driver Hybrid As you can see from above, they are very similar, but not identical sounding (1MORE version is also slightly less sensitive and lower in impedance) If you don't know what 1MORE multi-driver hybrid is - it is the original design of XiaoMi Hybrid. They had a crowdfunding event in China a few months ago to produce the 1MORE version and I believe a few hundreds early bird units was released, then somehow XiaoMi released its own version on the Nov. 11st. before 1MORE quietly releasing its retail version some days later. You can think of the 1MORE version is the more expensive but better looking of the twins (official site here: http://www.1more.com/product/show-218.html)
Yes. Just real-world stuff. Yet in just this thread You have 3 people, (myself included), who are claiming a distinct change in THESE Xiaomi Hybrid phones with hours used. Rather odd..... TWIN
Doesn't it just make sense that moving parts changes there behaviour over time? Have you ever felt the new vs old speaker surrounds? they diffidently degrade with age. Why do headphone drives differ? Every other device I can think off with moving parts change with age. For example car engines
All mechanical devices have a "break-in" period, and they will always get looser and looser with usage until that part fails completely. The thing is with tiny drivers is that they're in almost every case already been tested at the production line for hours to make sure that they are good to reach market. Even after that significant audible differences have never been measured. And note that the measuring equipment used are much more sensitive than the human hearing. The brain though is a wonderous thing and it changes your perception moment to moment depending on many emotional, physical and environmental states. So you do the math.
I do notice a slight change in brightness, bass slight tighter after burn in. I tested it after 8 hours of burn in. And also xiaomi has burn in app for android users. Innerfidelity has a 1 more multi unit earphone measured under Headphone Data sheet download. Wonder if they refer to the same earphone...
Burn in or not, these hybrids are only good, not excellent. You would be hard pressed to tell that they are hybrids if you didn't know beforehand. The clarity and extension simply isn't there. I fully welcome a market of $20 hybrid competition however, so props to Xiaomi for getting the ball rolling on that.
I think xiaomi failed to give justice for a hybrid iem. But for $20, it is somehow a bang for the buck for its performance.
Yep, same one. The name 'multi-unit earphone' is how 1MORE is calling the IEM - but it is basically a direct (and wrong) translation of its Chinese name. I guess someone at 1MORE didn't bother to check whether Google Translation is correct or not. Actually you can tell that my measurement is somewhat similar to that of Tyll's, though probably not nearly as accurate.
As you wish: Green is stock, blue is with front vent blocked, red is back vent blocked and grey is both vents blocked. Interestingly enough, 1MORE responds much more sensitively to blocking vent where XiaoMi only cares about whether the front vent is blocked or not.
