SKU: 8mm XWB IE800 Drivers (Titanium) Category: Tags: , , , , , ,



This XWB (Extra Wide Band) driver with 8mm diaphragm offers 5-45kHz frequency response. Compared with the IE800 released in 2012, this new model is built with pure Titanium diaphragm and better driving technology, and has been applied in Hi-End earphones with Hi-Res certification. 


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.
