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


  • 1 Pair (2 pieces) 8mm XWB Drivers
  • 2 pieces of front cover spacer (for air sealing in installation)

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 IEC711 coupler, a customized USB sound card and Win10 PC running ARTA Software.

Frequency Response measurement

Note the driver have output even at 18kHz+, the benefit of pure Titanium diaphragm!

Frequency Response


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

Burst decay

Proceed with caution: dynamic drivers are with extremely fragile (1~5μm) diaphragm and can be easily damaged in following situations.

  • Soldering: overheated (>250 degree C) soldering iron or overtime soldering (>2s) may permanently damage the driver. Please heat the driver as little as possible during soldering.
  • Installation: the driver has Sintered NdFeB Magnetic inside with extremely strong attraction power. The fragile diaphragm may be damaged by having anything metallic hit it. 
  • Gluing: attaching glue either to the diaphragm or the backside holes may greatly alter the sound
  • Chemical: Applying any chemical solvent will void your warrant and we will not be able to help you
  • Others: applying high-voltage, storing in high temperature/humid environment… all may cause unrecoverable damage.
