Dekoni Audio Blue – Fostex/Dekoni HiFi Audiophile Planar Magnetic Headphone

The Dekoni Blue is a collaboration between Dekoni Audio and Fostex, the only T50RP MK3 modification officially approved by Fostex, featuring redesigned Blue cups, a new inner baffle, and Dekoni's Elite Hybrid ear pads. Warmer, smoother, and less fatiguing than the stock T50RP MK3, the Blue transforms one of the most modifiable planar magnetic headphones ever made into a refined, all-day listening companion.

Type and Technology

Closed-back planar magnetic headphone. Based on the Fostex T50RP MK3 semi-open platform, modified with Dekoni's Blue cups and new inner baffle that shift the presentation toward a warmer, smoother character with extended bass and a less forward top end. Dekoni Elite Hybrid ear pads, a combination of leather and velour, are included and installed as the only ear pad option. Fostex T50RP MK3 driver and headband retained.

Sound Character

Warmer and smoother than the base T50RP MK3, great bass extension with a smoothed-out high end and reduced listening fatigue, making it genuinely suited to long sessions. A fun and musical alternative to the more analytical stock T50RP presentation.

Best For

Listeners who want the T50RP MK3 platform with a warmer, more forgiving presentation, and those who want a Fostex-approved planar magnetic headphone with enhanced comfort and tonal warmth out of the box.
