Oppo PM-1 Planar Magnetic Headphone Impressions Thread - Page 118

post #1756 of 3442

Now I'm thinking most of my experiences with the velours might've been towards the beginning of my listening period, so maybe the break-in period has something to do with it.  I will do some more listening with the velours and see if anything has changed.

In my experience, velour usually subtracts some amount of bass. The exception being the he400 where the bass seemed "retained."


it seems to me,and i am by far no expect, i'm just guessing that this situation would be not unlike speakers.

ported speakers allow for deeper bass from a smaller, more easily driven speaker, whereas a sealed speaker may have tighter, faster bass, but may not ultimately reach as low as a similarly sized ported speaker

the leather should provide a better seal, allowing/forcing air to escape from just the open back, where with the velour , more surface area for air to escape , i guess i'm saying it seems the difference in pad material would effect the type of bass, more than the amount ?

Looks like a classical case of cognitive dissonance (conflict between subjective vs authoritative claims) hehe.

Gotta love it...

I'm curious to know how the tests were/are conducted.  Is it with a sensitive mic that sits in between the headphones?  What's the distance?  The only reason I can possibly think of the difference is how the head affects the sound.  Wouldn't sealing the headphones with your head cause for more "gain"?  On the same token, if the velour pads are more perforated, wouldn't that mean more energy escapes from said seal?

 

I'm "relatively" new to headphones, but it seems like a difference between an enclosed room or a room that leaks to another room in a stereo or home theater setup.  The measured frequency that manufacturers measure from are from anechoic or semi-anechoic chambers, which doesn't account necessarily for room gain, reflections, reverberations, etc.

 

I'm more thinking out loud than anything else...

The graphs from Headroom and innerfidelity are measured using a dummy head system that has a coupler and mic built in as a system. The head is used to replicate the parts of the ear, the coupler replicates the ear canal. The graph is then compensated using standard diffuse field compensation to compare it to what a flat speaker would sound like.

Awesome!  Thanks for the information!  I'm definitely going to have to listen more with the velour to compare, then.

After a week of delays with customs, which caused me to not get these in time for my trip last week, I finally got my paws on the Oppo today.

 

Some general thoughts (a more detailed review to come in a week or two):

 

Packaging:

A very nicely packaged box, with everything neatly placed inside.   Reminds me a little of the packaging that expensive Japanese maki-e fountain pens come in, actually.    That being said, from the description here, I was expecting something different and a lot more exotic.   Personally, I think the LCD2 hard case is a lot more practical but this one sure looks nice.  I am going to put it away and put the cans in a Hippo Case for storage and travel, however.

 

Fit/Comfort:

Very comfortable!    Not weighing half a kilo helps.    They are on par with the HD800s and the HD650s in comfort, atleast on my head.

 

Sound:

I like a warm sound with smooth, somewhat rolled-off highs and a prominent midrange.  I like the HD650s and love the LCD2s - and despite all of that, manage to get along with the HD800s for some genres of music.    The Oppos have a very smooth treble, and have the kind of sound that I can listen to for a long time - non-fatiguing, smooth and well-balanced, without too much in the way of artificial coloration to create a short-term impact.   

 

However, while these are very nice, balanced headphones, they arent a patch on the LCD2s.     The LCD2s have weight and dynamic impact that leave the Oppos behind.     In the first movement of Solti's stirring rendition of Dvorak's 9th, the LCD2s have a slam that made me jump the first time I heard it - the Oppos recreate it well but lack that visceral  body, weight and dynamic impact.

 

I also feel that the lack of top end energy is affecting timbre and, for want of a better word, "bite" - many instruments that have their primary notes in the midrange have a leading treble edge which gives them a sharp and distinct sound live;   done wrong, this can be reproduced as a bright, fatiguing sound or a more polite rendition.    The LCD2s, to my mind, come the closest to doing this right (and so, surprisingly, do the NAD HP50s) - the PM1s err on the side of politeness.     This isnt a bad thing - they lack a little of the immediacy of the LCD2s, but they do a lot of other things right - weight, comfort, portability and an easy-listening, balanced sound where you can stop obsessing about audioweenie traits and focus on the music.

 

Summary

I am keeping them.    Purely on audio quality, I probably wouldnt spend $1100 on them - however, I have been looking for a pair of transportable headphones for use in hotels and these fit that bill perfectly, and their weight & comfort is worth a premium for me.    

 

And for the record, even though my post comes across as lukewarm, that isnt the case.   I like them a lot - they will probably get as much head time as my LCD2s (given my hectic travel life), and I've been looking for a pair of headphones to fit those requirements for a while.    With these, that search has  come to an end.

You can now purchase the PM-1 2m Balanced Headphone Cable ($129.00) and PM-1 3m Balanced Headphone Cable ($149.00). Both cables are OCC and are shipping immediately.

 

We will be releasing the PM-1 Headphone Stand ($79.00) as a separate item for people who already own the PM-1 and then decided afterwards to get the headphone stand, or for people want another headphone stand for their other headphones. They should be available later within a week or two for individual sale.

 

EDIT: Fixed when the headphone stand would become available. Meant to type originally "later this month" but typed "later this afternoon" by mistake.

Just purchased the 2 meter cable 5 minutes ago.  Thanks for making these available at a reasonable price.  I still have enough money left over for an HA-1!

Hope the cables meet your expectations and congratulations on the 500th post *throws some confetti*

I think the headphone stand was available as an addon when purchasing the PM-1,
but it went OOS like a week ago.
It still shows OOS on the accessories page. Is there an ETA on when more will be available?
