I received a Jiffy bag with just the left and right Zeniths without the filters installed and the 2.5mm silver cable.

yes, 2.5mm balanced cable.

Thanks I'll email Bob and see what I can find out.

My replacement Zenith was waiting when I got home from work. Just amazing customer service! Quick question the new silver cable isn’t keyed it just has tiny coloured dots. Do you know which way round should they should be inserted so they are in phase? Thanks

Thank you! I'll give them a go. -- Iain

Can I translate these settings to equivalent eq settings for the Cipher cable ?

I am glad you had a chance to test them James,  I may have been confusing sound stage with 3D imaging and separation.   As for the tips I think that the proprietary design maybe because Sennheiser needed another guard mesh on the tip as well as the bud to prevent any particles getting into...

That is it out of the head,  not heard anything like it in an IEM.   This is an from the same family as the IE8 and 80 so the bass maybe too much for you. 

Depending on the song the bass is DEEP.  Listening to Nelly Furtado ( don't judge me ) maybe too much but you can still here loads of detail.   I think I'm just lost in the sound stage it's vast.

The IE800's only arrived this morning no burn in or brain burn in yet but for so far I really like them compared to the rest of my collection. It is hard to explain there seems to be something different going on to other IEM's they sound like full size headphones HUGE sound stage.   Again...

I have a BIG problem only came to Head-Fi to find a good ear bud to replace the Apple buds.   Yuin PK1,2,3 Yuin GA1,2 Blox MC2,TM5 HifiMan RE0, 262 Fischer DB2 Sennheiser IE8, 800 Westone W3,W4 Sennheiser HD650, HD25 II JVC FX700 Panasonic HJE900 .... .... ....  ...

I have a lot more respect now for the regular reviewers I have come to trust on Head-Fi it really is a skill to describe sound quality.   The IE800 to me are unlike anything I have heard before and I may not post much but I have big headphone problem that my friends will attest to.

Take all this with a pinch of salt I could be completely wrong and everyone will hate them.   On testing a new phone you always wonder is this going to be the one that ends your Head-Fi journey of incremental improvements.  After the initial un-boxing excitement of getting a new toy...

Okay guys I will try my best to answer any question, obviously if you can test drive these first all the better as they are so very expensive and some of my comments may be new toy syndrome.    The IE800 cable is 1.2m according to the Sennhierser web site but is it only 25cm from the buds to...

I was hoping James would get them first as I love his reviews.   -- Iain
