This is a pair of 8mm XWB (Extra Wide Band) driver unit offering 5~45KHz frequency response. Compared with IE800 which was built in 2012, this driver is with the upgraded Titanium diaphragm and driving technology, and has been applied in several Hi-End IEMs with Hi-Res certification.
Features and Specs
We recommend using it with our IE800 Ceramic Shell.
What’s the difference with the 7.8mm XWB driver
There some major improvements on the structure and sound characters:
- Physical strength improvements
- The front cover changed to stainless steel
- Add a protective copper ring to the diaphragm (and increase the outsize from 7.8mm to 8mm)
- Upgrade of the diaphragm to a pure Titanium diaphragm made in Germany (note it’s not Titanium Plated diaphragm used in many low-mid end earphones)
- 1-1.5dB increase on the overall sensitivity
- +2.5dB on low/mid bass, which is now more punchy and deep
- -5dB on 7-9kHz to effectively suppress the harmful sibilant
- Extend the high-treble at 10Khz and 15Khz- 20kHz, and increase airyness
Some limits you should know
- 3kHz mid is a little bit emphasized (+2dB), meaning the vocal getting more obvious.
- Impulse response latency is slightly longer (+0.2ms) due to the low-bass extension.
- Pure Titanium diaphragm needs ~10h time to burn-in.
Measurement is based on an , a and Win10 PC running oftware.
Frequency Response measurement
Note the driver have output even at 18kHz+, the benefit of pure Titanium diaphragm!
CSD (Cumulative Spectral Decay), i.e., the waterfall diagram. Notice the decay rate at 500hz-20Khz is very consistent, meaning less interference among bass, mid and treble.
Cumulative Spectral Decay
Impulse response – notice the response duration is extremely short <1.4ms, meaning the response of this driver is very good.
Burst Decay – notice the consistency among all the bands
