Sennheiser Genuine Adapter Cable Female 1/4 6.3mm to Male 1/8 3.5mm Plug for Headphones

Does was its supposed to do and shows no degradation of sound quality.

I use a Fiio Mont Blanc for portable amp. plugged to my iPhone or iPad and found that it is the best and most handy adapter to join the male 1/4plug of my HD 800 .to any portable devices.

Excellent quality. My old reference standard headphones can now be used with my iTouch and i Phone

Works perfectly. Cant expect anything more from a cable adapter.

Quality due any high end headphone

The Sennheiser HD 599SE headphones come with a shorter and a longer cable. Unfortunately the lengthy cable has a large jack for an amplifier, etc. An adapter does come with the package but it makes both the length and weight quite undesirable and may cause undue internal stress at the site of the port. An alternative is to purchase this pricey jack adapter. I was unpleasantly surprised that it is even more bulky than the original. The saving grace is the 4 1/2 inch section of flexible cord that helps with positioning. The connection is tight and fits together easily. Would not advise using an alternative to the Sennheiser brand if concerned about possible change in sound quality.

Works good but the price is kind of ridiculous! Also it barely fits my M8 phone with a case on it.

No issues... does as described.

perfect

It was the one I wanted since I have a set of Sennheiser HD800 that I plug into my Cayin n5 and I wasnt getting a good connection with the adapter I was using.This one did the trick and now I am a happy camper.No static,good connection,snug fit.Id certainly buy it again and recommend it to all those looking for this kind of adapter.Top of my list.Quality product.
