They are okay.  I will reserve judgement until they burn in more. They do kind of remind of the Sennheiser HD-700.  Sounds good but some tracks the highs are a little bright for my taste.   I still prefer the HE-400is over these.

  Right now the HE350 has too much treble.  The HE-400is are more balanced/neutral.  The bass impact is lacking on the HE350 right now.   Mids are lacking a bit as well.   It really is a little too early for a proper comparison but these are my initial impressions.

Mine just arrived.  They seemed bright right out of the box but the highs began to smooth out after about a 1/2 hour of listening.   I am curious to see how they sound after 24 hours of burn-in.   iPod Classic -> CLAS Solo DB -> RSA SR-71B -> HE350   These are the lightest pair of...

My original pair from the Amazon sale or the Amazon Warehouse sale do not bleed ink.  I just opened 1 of 2 of my Bass Plus Cushions.  I will leave them overnight on some tissue to see if they bleed.  The Bass Plus Cushions are also blacker in color whereas both original pads are a 1 to 2 shades...

It's good to hear that you like the combination of the 400i and the Venus Audio cable with the liquid carbon. I just received my cable too. However, I don't see any markings on the headphone connectors to tell which side is left or right. I know it will be easy to determine but both my...

  I think you are referring to PDPS.   PDPS - Pseudo-Dual Power Supply upgrade was incorporated into all WA6 amps built 2009 and later.   Pre-2009 WA6, it was an option.  I suggest you email woo audio with your serial number.  They will tell if the PDPS was factory installed.

  Thanks.  I just finished cleaning all the tube pins.  I swapped the driver tubes.  I dried the pins with a cotton swab but will wait another hour before I power it.

I can't see to find the answer but I just want to ask the obvious. Looking at the front of the amp, left set of tubes is left channel and right set is right? FYI, I get a hum on the left channel that comes and go if I moving or more precisely the amp jiggles from moving the cable. Amp is...

​The X2 seems a little hotter in the treble when I run it through my WA6-SE (USAF 596, 6FD7).  I am running FLAC files through a Sonos Connnect to a WDS-1.  However, the soundstage is wider.  The bass is better balanced than running it through my portable setup of an Ipod Classic -> CLAS Solo R...

  I am only referring to the impact you get from the HE-500.  I have modded all three versions.  With Jerg's mods on the HE-500, the soundstage is increased.  The X2 bass is more bloated than the HE-500.  The HE-500's bass is crisper, attacks fast with good decay.  I do wish even the modded...

Thanks for the input.  I just started breaking my pair in.  I agree the bass is a little too much for me right now since I listen to mostly EDM.   I using an ipod classic to CLAS Solo to ALO Audio RX Mk2.  If the bass evens out more, it will be another keeper.  I like the fuller sound I get...

The 10% code pushed me over so I ordered mine on Thursday night.  It still shows the status as 'processing' for the 400i.   It reminds me when I ordered a pair of T1s. It took that company almost 2 weeks to get me a pair to ship due to shortages.

I couldn't find the part number or link to the pads on their website.  I read on their support forum to contact the local dealer for pads.   Anyone got a link or part number to purchase OEM pads?

If anyone is looking for alternative or replacement X2 pads.  This is the only ones that I have found.   Bass Plus Velvet Replacement Ear Pads Cushion For Philips Fidelio X2 Headphones   Ebay Item number:  261967950938   They had 6 pairs at the time I posted this.  They sold 48 pairs...

The retail price of the HE-400s were $399.   My only hesitation about getting the older 400i version is the design change to remove the backplate that covers the driver magnets.  I would prefer the older connectors and no backplate.  It does not appear that the backplate can be removed from...
