I have 2 pairs of tenores, one of which I believe to be reference, and one which is bass heavy. My first pair I received were bass heavy (after comparing to impressions on this thread and my own pair of er4s) so I duly ordered another pair from amazon japan (which was easy since I'm based here). The 2nd pair I received has a much more balanced low end and they sound amazing to me with sony hybrid tips.

I read something regarding wire lengths earlier, and after comparing both pairs, the bass heavy pair has a wire length that is about 3cm longer than the reference pair. This difference is probably due to manufacturing variations from batch to batch, which might explain the variations in bass levels.

That being said, both pairs still sound darn good and I will be keeping both.

So that's the difference I will say. I know if you add cable length to the Tenore, the sound gets bassier and darker, so those batches with the shorter cable are the reference ones. I though it honestly had something to do with the big vent clogging but even blocking it makes little difference. Also, sources with high output impedance will also make them sound bassier and darker. 

 

Bass should only be the thing changing between batches I'll say, I think very likely the rest of the spectrum are pretty much the same between batches.

I can pull the housing out so that the tip is causing a good deal of suction and hold it like that, and the tips don't lose pressure.

Also if i wear them really deep, they have more bass, just like the stocks tips do when deeper. However, the bass with the deep fit is less than the bass with the stock tip's deep fit. By essentially the same amount of difference as the shallow phillips vs shallow stock tips.

Did that all make sense? Lol

 

It does... and it doesn't at the same time, lol. ;)  Anyway, you made me finally try those Philips tips myself. Result: I too get less bass with them. And I too feel a suction when I pull them out.

 

That said, they offer less support and don't feel as securely seated as the stock tips. And as soon as I add smaller silicon tips underneath, for better support... guess what? Bass is back to stock tips level.

 

 

(transparent + black dual tips do look great on them, no?)

You really think it's cable length? Any impedance differences would be negligible at those differences imo. And if blocking the port doesn't result in that wide of a difference, then it has to be something else. Hard to say what exactly. Dampening material could still be a possibility, the best one imo, until we find out otherwise. I may be performing surgery on my bass light pair soon.

The only difference in bass you would hear from the cable being a different length would be the fact that the cable length has something to do with a specific batch of them that happened to also have extra bass or something. Technically speaking, the physical length of the cable itself would not have any affect on bass in any way.


I use my tenores with a 10ft extension cable when I use my amp with apple tv on the couch.  And they sound identical with or without it. The only different a cable's length would have would be added impedance, but you'd have to have a REALLY long cable for that to add up. And even then, I use my tenores on my 32ohm duet and they sound identical on that as well (I've a/b'd it with my fuze which is <1ohm). So realistically, that is not very likely.

 

Coming from a certain batch that had different length cables would definitely be a possibility...

 

Maybe the 12 year old laborer that didn't know how to measure the cable length properly also didn't measure the driver position properly or something. ;) hahaha

Interesting. Mine are more secure than stock in terms of movement and "fit". They seem to seal about the same. Adding smaller tips underneath probably adds to the density. I have a feeling the low density of the silicon affects things somehow. Not really sure. Either way, I've been using them all day, and the sound is 100% consistent every time I put them in. So whatever the reason I have found my tips! :-) And they are sexy...

now that you mention it though, perhaps not. But the thing is, I just add a 1.2m iphone extendor and it gets noticeably bassier and darker. I may do surgery as well as I may want a pair recabled.

what extender is this you speak of? Are there components in it?

Just a generic cable extension with a iphone control and mic

Have you tried another extension cable to verify?

post #2784 of 5960

hmm nope, but apparently luisdent has and it didn't affect anything. But that can also mean the cable he used adds little resistance and the low quality one I used with low conductivity is adding enough impedance for it to cause a change. Wish I had a resistor handy. 

 

I will say a trick to make these sound amazing when you find them a tad warm is to find the balance between a leaky and sealed fit. Not leaky enough for it to loose bass and not sealed enough for it to sound dark. I'm using very small tips from my LG Quadbeat.

Honestly THIS is the IEM Sennheiser should've put out as the IE800. Sennheiser could've used their ceramic housing and thick cable to this tuning and charge 1000$ and it would'be been way more justified than the product they actually released.

Only if they can make the impulse response graph just as pretty. tongue.gif

I've been away from this thread for a few days and so much has happened. But as of about half an hour ago, I have a personal victory here: win another one for personal ear geometry and possibly a slightly less sealed and further away from the reference plane fit.

I know people have tried these with little success earlier in the thread so I was hesitant, but I threw on the smallest MH1 tips anyway because I was hearing things differently anyway and viola. The bass sounded flatter and the lower mids didn't scream out at me as being immediately off.

Running a controlled sine sweep back and forth and back and forth soon after, and, from the first time, they literally sound exactly as graphed by that one guy.

Time to give them another critical listening session as they are now "reference", but I can tell it's a solid improvement already. biggrin.gif

James, maybe they'll work for your ears too. Maybe worth a shot?

Btw, a solid bit of appreciation from me for luisdent, James, Inks, gnarlsagan, and anyone else who's name I don't remember off the top of my head for keeping the discussion on these going.

I've used it with 32 ohms and no change...

It's strange, but i'm sure there's something weird going on. I'd try a basic extension to rule out that specific cable being weird.
