Watch what you say about those Sennheiser HD-250s that just sold on eBay: I know the seller and have just alerted him to this forum and this thread!

Hope there ok then, and as good as description implies. He's a good and trustworthy eBayer, and has helped me enormously with my headphone journey. He knows his stuff and relies on the weakness of the pound/strength of the Euro to sell his surplus gear at top prices!

No where your coming from Spirit, yes they are expensive but ive been after a pair of these for a long time, and dont mind paying for the privelege of having an "as new" pair, as the opportunity does NOT arrise too often, even in a well used, and possibly abused condition.
Will let you know my opinion of SQ and condition when they arrive.
Mick.

Mick,
They are a nice headphone. On some recordings, you would think ... no bass and then on others, it's so deep it rattles your teeth.
It doesn't have the Sennheiser 'bloom' and is very lightweaight on your head.
This and the Beyer DT150's are the ones I use for work.
Ian

Yes Ian, it appears that the seller has previously sold a pair to a Forum member, that have turned out to be "Bass light", possibly the later model with the heat dispersing ring, will have to see how this pair performs, hopefully i will be happy with my purchase . Wont know till i try, fingers crossed Mick.

As Ian says... when the bass does kick in it will make your toes curl up.... I have two pairs of these puppies now and keep one pair in their original box (they are still under warranty / 2 years left to go!) so hopefully I'm good for 250's for the forseeable future.

Wont know till i try, fingers crossed Mick. I see. Well don't panic if you don't hear bass and start to think it's the old one Mick. Just change the recording. You'll know straight away because it really kicks ass in the subwoofer area. Ian

Oh dear, unless he has a twin brother called Colim, who sells the good ones, looking like mine might be BASS light too .

Oh bloody hell... they will probably be ok Mick but I know that Colin is a collector of these 'phones (in a BIG way) and pretty much buys them all up... he will certainly be able to tell you all about the heat dissipation rings.... Do ask him about these 'phones he is selling and his opinion on them compared to his special vintage stock

Yes, we are more than curious to see what these heat rings look like Once we know where they are and what they look like it maybe possible to remove them

Heat ? dissipation ? what heat needs to be dissipated ? Surely not the few mW ? If these rings were situated around or near the voice coil these were used to flatten the impedance of the voice coil at higher freq. This trick is used more often I believe. It seems more likely this is what it was intended for originally, there is no heat to dissipate in HP's.. Well... maybe.. when you are driving them at deafening levels ;D Just an observation.. ;D

Below is the reply i have received from Colin today, which i am extremely grateful for, and which is VERY comprehensive and informative. Hi Mick, I had a look at the thread, - all we be explained and don't worry the headphones I intend to send you are not bass light! I'm no real expert but there is some confusion over this heat dissipation disc thing! I've had a lot of pairs of these headphones and there are two main type of driver, the EARLIER one has an extra ring in it (yes that the copper thing) and the later version LACKS this ring (opposite from what is written on rockgrotto). The two different types of driver also have a different looking membrane/diaphragm, -the later one is less transparent (so I assume its different in material somewhat from the earlier one) and has a black circle in the middle whereas the older one has a white circle in the middle (actually on the diaphragm). The reason I know this is because I've opened up pairs in the past and looked and the easiest way to identify which driver it is phone is by the circle on the diaphragm white=old black=new. You can quite easily see by just removing the ear foam without even taking it apart. What I have found in my experience is that neither type guarantee a great sound and every HD250II I have ever heard has sounded slightly different (I have had about 15 pairs!), - some better than other. Why this is I am not completely sure. I think there is some inherent sound differences between different driver batches of both types. I think Sennheiser`s quality control in making these phones was not that great and there is a big variation. There can also be some bass response differences between pairs of either driver type and I didn't know what it was until PF (mike on rockgrotto) investigated, - the port sealing does have some effect on the sound. The conclusion I have come to is that some driver capsules must be of slightly different dimensions to other ones and on some phones the port is not sealed properly, - the pair that Spirit bought probably just need this sealing done better. I use blu tak for the port sealing (and different amounts of it can change the sound, - you have to fine tune it to you tastes), - blu tak though is probably not as good as butyl rubber. So what I’m saying is you can get good and bad sounding phones with either drivers. My current best sounding pair (to my ears) is an earlier driver type but I had a best pair before that broke (those nasty little wires!) which was a newer driver type. I am not 100% sure that ring is a heat dissipation ring (and I am the person who told PF that). I was alerted to that rings existence as I sent two drivers with broken wires (one an older driver type and one newer type from two different phones) to a guy from the crossover forum (who was recommended to me as someone that might be able to repair them), - he noticed one driver had an extra ring and it was possibly due to aid heat dissipation, but he wasn’t sure exactly. So that’s where I got that info from, but I misunderstood him at the time and it was the wrong was around (I confirmed later by looking at drivers) - the earlier driver has the extra ring near the magnet part (and a different looking membrane with a white circle on it) and the newer driver does NOT have the ring (and has a membrane with a black circle on it). I was not 100% sure they were heat dissipation ring but it seems though that PF rang up Sennheiser and asked about this “heat dissipation” ring and they were aware of it so it might well be a heat dissipation ring. The pair I am intending to send to you have the newer drivers type. They have an excellent sound and great bass response, in fact I bought these particular ones from the same place Nigel (who I know) bought the ones he pair to PF. The serial nos are very close together so they are 99% likely to be from the same batch. They have great bass, - I am sure PF will tell you that and a great sound. Tell him to have a look at his pair, - they will have a black circle on the membrane as these do too identifying them both as newer drivers without the extra copper ring. The port sealing on them is good I think and already and that’s why the bass is good. I have 7 pairs, - 4 with the old driver, and 3 with the newer driver. I had a newer type with little bass and I recently did the port sealing trick on it with blu tak and now it sounds very different and much better than before. If you like I could send any of the other phones I have if you are worried about the difference in the drivers. Or I could send you several and you could chose the one you like best if you like. I know that the particular pair I had intended to send you sound great, - so hopefully you’ll trust me that they sound good. If you are unhappy I’ll gladly give you a refund or swap them for another pair. Like I say I’m also happy to send you a few pairs to try but in my opinion this is one of the best sounding pair I have for sale. I am sure you will be very happy with the bass on them. Like others have said you will know if they have good bass extension when you hear a track that has some sub bass on it, - they sound great on the phones, - try maybe (80s I know!) Enya’s Watermark album track 1 about 50 seconds in. Or you could try the track on it called the “Longships” which is about track 10 I think, - it has a lot of bass around 30Hz or so in it. You might be able to increase the bass on them even more or change the bass balance by adding some sealing stuff to the port on these phones but I would say they do not need it so I’d leave them alone if I were you (as what I’ve found is sealing the port might increase the bass but does not always make the sound better)- I’ll be interested to know what you think of them so let me know how you get one. In the meantime please feel free to post this info up on the forum so it will shed some light on the heat dissipation ring issue. All the best, Colin
