The oBravo ERIB-2W earphones combine the most advanced headphone driver technologies to deliver the best bass performance of many IEMs in its class.

The Enhanced coaxial structure design enables a new listening experience that even most overhear headphones can’t provide.

Main Features:

  • First coaxial two-way design
  • Combines Planar Magnetics Driver (PMD) Tweeter and Neodymium Dynamic Drivers.
  • Enjoy ultimate sound by adding one of Moon Audio's balanced IEM cables.

With oBravo combining a Planar Magnetics Driver (PMD) and the Neodymium Dynamic Drivers (NDD), the ERIB-2W delivers better bass performance than many of the IEMs in its class.

From studio recordings to live performances, the PMD and the NDD stage a full spectrum of audio. Every nuance is captured and heard. Every note is felt.

Each Obravo IEM comes in 3 shell finishes. This being the driver acoustical outlet structure. 3 options are available in Aluminum, Wood or Ceramic. The ceramic is basically porcelain. This provides a different resonance and thus affecting the tonality of the IEM.

We have chosen and listed the versions on the website we prefer in each model series. Note the A, W or C at the end of the product number. The Aluminum versions tend to be faster paced and more balanced sounding. The Wood tends to sound smoother and more musical. The Composite tends to be more analytical and resolute. But this does not predict the overall sound as the drivers come into play. So feel free to contact us with questions as to the best choice for your desires.

The rich wood design of the ERIB-2W not only looks elegant but is also extremely comfortable.

Advanced Headphone Driver Technology

OBravo has successfully packed a tiny 8mm magnetostatic driver and a 10mm neodymium woofer to form an earphone that will give you a powerful and accurate sound.


While the oBravo ERIB-2A might be larger in size compared to most plastic-clad earphones, the ERIB-2A is not bulky or even heavy.

Like the oBravo HAMT-1 headphones, the ERIB-2A also flaunts a similar wooden soundboard with an aluminum enclosure. The wooden soundboard also includes reflex ports and comes with unscrewable leads.

Note: For the wood cup designed model, ERIB-2W, or the precision ceramic ear cup design, ERIB-2C, you must place a special order. Contact [email protected] for more info.

The foam pads from Comply come in three different sizes and form a comfortable fit within the ear effectively closing out ambient noise for a more punchy bass.
