Essential ETHER Flow Upgrade


Product Description

The Essential upgrade allows you to convert your open ETHER to either an ETHER Flow or an ETHER C Flow, that retains your original carbon cups or red grill. If you wish to convert from open to closed or vice versa, that is NOT possible with this option, you must order the Complete ETHER Flow Upgrade.

Note:  If your headphone baffles are damaged when we receive them we will contact you regarding possible repairs.

The Essential upgrade includes:

  • Upgrade and replace both drivers**
  • Add “FLOW” slider to headband
  • Certificate of authenticity and SN registry entry

*Original Open ETHER headphones use silver bolts on the headband assembly, while ETHER C and both flow models use bronze-tinted bolts.  The bolts are not replaced for ETHER headphones, other than that upgraded headphones will be identical to new Flow headphones.

**In order to precision match drivers we will need to remove and replace one of the baffles.  If your headphone has visible damage to the metal baffle we will notify you and offer the option to replace the damaged part for additional expense.
