exactly. we have a 5 month old kid, so what i needed this time was near perfect isolation.
btw i've had these for around 5-6 years or so:
these are called goldring dr150, and these are basically some sennheiser inspired open cans. great sound for the price, very clear, transparent, neutral, awesome with female vocals. some call them a hidden gem, highly recommended if one can live with the cheap plastics used. but as they are open, they ended up in a box in the loft after the baby arrived.
