he60 & O2

Recommended Posts

Both like to be cranked up high, especially on a BH, but I'd say the HE60.

I'd agree with that. I think it's mostly the more forward nature of the HE60 that makes it a bit more enjoyable at low volumes, but as Spritzer said they both open up well at higher volumes.

Thanks for your replies :)

Are there any issues to buying an O2 mk1 second-hand like with the HE60?

Do the drivers respond differently to environmental conditions over time? dust? wear?

In for sale listings I hardly ever see people advertise them as being stored under a dust cover.

This worries me, considering the price they go for.

Also, I've seen reports of people buying different versions of O2's.

I think most people store them in their box. I think the O2 in general has less aging issues than the HE60.

The SR-007 drivers are all completely sealed I wouldn't worry about them. The cable is an issue though and can crap out at any time... :(

When the day comes that my O2 cable gives out. How easy is an inept owner repair/replace?

Very easy but the soldering is not for the faint of heart since you are soldering directly to the driver. Basically you remove the earpads/spring, remove all 6 screws and the black backing plate. Then you access to the cable behind the small masking plug, desolder all the connections and the old one is gone. The new one uses the same system as all other Stax cables, line=+, middle wire is bias and the last one is -. Just remeber to cover up the driver with something solid (cardboard perhaps) before soldering.

Or just send them to -=her=- for repair. :P

I'd rather cut the cables off and use them as ear muffs. At least then I'd get to keep my broken stuff.

I always store mine either in a clear dust cover type bag, or put them in their case if unused for a while. The O2 is a solidly built phone, but as with any headphone you'll want to take extra precaution with the cable entry into the drivers. The MKI especially does not have an effective strain relief to support its heavy cable and with even minimal carelessness it can turn into failure.

The cable is an issue though and can crap out at any time... :(

The cable seems too heavy. I feel like I always have to pick up the cable a couple feet from the strain reliefs to support it or else they'd snap right out of the cups just from the weight.

It was great how people in my HF WTB ad came in to warn me against buying from him, I've gotten warnings in emails as well. Does anyone know if those are his own pictures for sure this time?

Why doesn't the strain relief on the O2 work like it should, anyway? What kind of strain should I be especially careful not to apply on the new O2 cable I'm about to install? My old cables were working fine until that one time I stored it in the box for a relatively long period of time.

@manaox, i shouldve known that, apologies to all for using the absolutely most tactless and tired of ways to ask that question

That aside, does anyone know if a near-NOS he60 will likely have o-ring problems imminently?

Use has no effect on the o-ring aging so it probably will need to be replaced. I've owned two supposedly NOS sets and 3 of the 4 o-rings were broken.

I'm talking about the near-nos he60 on the other site btw,

it seems 1900 is pretty steep considering the cost of shipping and duties etc, all just to replace such a simple part like o-rings

what is a fair price for a NOS or a near-NOS he60 these days?

The O-rings hold the driver in place. They are under some tension as soon as they are installed. Wearing out is likely to be a simple function of time, and not depend on use. So yes, I'd say that any HE60 is likely to have broken O-rings.

The replacement O-rings cost around $20 from Sennheiser.

The skill set needed to perform the replacement is ability to use a philips screwdriver.

O2 = gateway drug for BH...

The exact same thing can be said for the he60, which responds far better to many other amps.

Then again, the OII just does not work for me, BH or no.

...especially when powered by the BH. :o

The HE60 needs power almost as much as the SR-007 and so does the SR-X Mk3 Pro... :D
