By integrating Fostex's Planar Magnetic Drivers and Body, along with Dekoni Hybrid Ear Pads and other exclusive modifications, this headphone improves upon the original design. The enhancements result in reduced listener fatigue, smoother sound quality overall, and extended bass response.

What a load of BS by the other reviewer

This is actually ridiculous, you cannot get permanent tinnitus from 2 hours of loud music. If that was the case, every single person who went to a club even once in their lifetime would be having permanent tinnitus (instead of the temporary one). Please refrain from spreading misinformation as many people will actually believe it. /rant end

Now onto the actual headphones. I believe these are the perfect pair of headphones for my taste. Warm with slappy bass but at the same time not muddying the mids and recessed highs (with absolutely no noticeable sibilance on the volume that I listen). My ears cannot tolerate treble spikes as well as sibilance so I was very happy with these. The semi-open back design also added in a nice soundstage surprise. These quickly became my daily drivers and I am in love with them.

Little background on these headphones - These are actually a mod of the insanely popular T50RP MK3 headphones These have seen a lot of different mods and some of the popular ones include the ModHouse Argons MK3 (I hope to own these someday). The Argons are definitely superior to these (IMHO) in terms of the sound quality as well as comfort. But these are by far much superior to the OG T50RP MK3. Dekoni makes some insanely comfortable pads and these are no different. I also love the tuning changes they have done to the actual headphones. These are by far the best T50RPs available in India (and at an insane price thanks to HPZ).

Hi there,
We appreciate your feedback and are sorry to hear about your experience with the other reviewer's comments.

We're glad to hear that you're enjoying the Fostex X Dekoni Audio and that they meet your preferences in terms of sound quality and comfort.

Permanent Tinnitus after 2 Hours of use

I am suffering from Permanent Tinnitus (Ringing ears) with no cure after using these headphones for two hours straight. The volume of these headphones felt low however what I didn't realise was that the higher frequencies were much ouder than the source. This condition has no cure and I spent a lot on ENT specialist but with no relief. Never knew silence was a luxury. Stay away from these unless you know exactly what you are doing.
