Goldring NS1000s leak too much sound - other options?

[if...]

I have the Goldring NS1000 headphones running through an Onkyo ipod dock and Cambridge Audio DAC and love the sound - but I am no longer allowed to listen to music late at night as the missus camplains about the amount of sound they leak. Installing the wife with ear plugs isn't an option - so what are the alternatives (apart from separate bedrooms)? I am not keen on in ear buds so am looking for, ideally, an over the ear fit like the Goldrings.

I have found these, which seem a bargain, but don't know anything about them - any suggestions?

Seeing as I paid £50 for the Goldrings I don't really want to go beyond £65ish for the replacements...

The only headphones I know do not leak and are in your budget are the portable on ear Sennheiser PX200s. Compared to the Goldrings and the sound will be noticeably more recessed and thinner, partly due to the much smaller enclosure and driver.
