High-value bonus included Sennheiser IE900

Selling because I no longer have opportunities to use them due to using other earphones.

These are the IE900, the flagship wired earphones from the prestigious German audio brand Sennheiser.

This high-end model features an advanced acoustic design with their unique X3R technology and a high-quality aluminum-machined housing, offering outstanding resolution and a naturally beautiful sound.

Product Condition:
• All accessories have the same serial number.
• The main unit has minor scuffs and small scratches, but these do not affect performance or sound quality.
• Operation confirmed; sound output is normal for both left and right channels.
• Cables and accessories are in good condition.
• Operation confirmed; sound output is normal for both left and right channels.
• The right MMCX connector is slightly loose, so we recommend using it with the included anti-rotation rubber holder.

Included Accessories:
• Carrying case
• Detachable cable (MMCX)
• Genuine 2.5mm balanced cable
• Genuine 3.5mm unbalanced cable
• Genuine 4.4mm balanced cable

* Everything shown in the photos is included.

Three Bonus Items:

① High-value custom cable: 24-core, 1176-strand gold-plated silver-plated braided cable with expandable MMCX and 4.4mm connector, specially customized for IE900 MMCX.
This cable dramatically changes and improves the sound, so please try it. (Custom order cost: ¥30,000)
Once you use this, you won't be able to go back to the genuine cable.
I use this same cable for all my other earphones.

② Since the right MMCX connector felt a bit loose and prone to detachment, an anti-rotation rubber holder for MMCX connectors is also included. It's recommended to use this to prevent MMCX wear and tear.

③ MMCX ASSIST

Please check the photos for the overall condition.
