Replacement Audio Upgrade Cable for Sennheiser HD4.40, HD 4.40 BT, HD4.50, HD 4.50 BTNC, HD4.30i, HD4.30G Headphones 2meters/6.6feet

I have looked around for a long time to get a replacement cable for my Sennheiser HD400s headphones. The official cable is expensive and is always out of stock, so I took the plunge with this one after a lot of research. Pleased to report that it works perfectly well with them, and suspect that any replacement cable for the listed HD models in the description are. The connection to headphones is solid and the cable appears to be of good quality. If anyone has problems with the 2.5mm connection make sure it is inserted all the way in by turning it left and right a little to find the entry point to the locking pin then twist it clockwise into its secure locked position.On a side note for anyone researching cables for the HD400s headphones, I can't speak for cables for the listed HD models in the description that have a 2.5mm jack on the headphone connection and that have a volume and mic addition to the cable work as I have not tested any of those, but hopefully this one will last some time and can state that it works perfectly. I plan on buying another as a spare.

Replaced original cable that failed - this one seems much higher quality and is longer than my original cable to boot - can’t say I notice a difference in audio quality but better than Bluetooth mode I was using in the interim!

Bought another cable which was supposed to work for HD 4.50 BTNC but didn't. This one is quite a tight fit but does work well.

Amazing quality and sound, I think it sounds better then the original cable

Excellent quality, a bit on the expensive side.

My original Sennheiser cable frayed at the edges due to wear and tear, so I bought this one. It fit perfectly, worked straight out of the box, and it's long enough on its own that I don't need an adapter, unlike the original. It feels far sturdier, and a lot more durable.If only Sennheiser offered audio cables like this instead of a ribbon cable!

Can hear audio but doesn't work with the mic on the GSP 500

This is a banging cable. Good quality, long, massive improvement than the original cable that is included with the supported Sennheisers. More cables need to be like this one.

Can't even enjoy music with this trash cable.

Ca a l'air d'être un très bon câble mais PAS compatible avec le Sennheiser HD 599 !

Il cavo mi sembra robusto. Fin troppo lungo. Buoni i connettori da entrambi i capi.

El cable vienen con un fallo y solo se escucha de un lado.el anterior a este que también lo compre por aqui dura poco tiempo.

Super, passt und funktioniert auch an meinem Sennheiser Momentum 3.0 Wireless. Gute Kabellänge (länger als Original). Stabile Stecker (das Original ist gleich abgebrochen, als das Telefon mal runtergefallen ist). Schade finde ich bei diesen DIY Ersatzkabeln oft, dass viele so eine billige, harte Plastik-Gewebe-Ummantelung haben. Eine weiche Textil-Ummantelung würde sich deutlich hochwertiger anfühlen. Dafür würde ich auch mehr zahlen. Aber okay bei dem Preis.
