my second pair of DT150 because i just love them so much. my first pair went well with the usual burn in and are stunning phones. i have always been a bit dubious about burn in but still feel it achieves something.
my second pair of DT150 were all over the place, with an obviously and irritatingly unbalanced chanel and frequency reproduction. So i thought before taking them back, lets fry the things and see what happens.
i put them through the musical fidelity amp at full volume with extreme bass rich and full/excessive frequency music, horrendous i know, but there was no distortion. i can hear them across the house while they're hugging a pillow. i can hear the bass in the room. i was honestly concerned of them melting down and catching fire while i was out.
i'm onto my fifth day of this procedure 24/7, and the results are nothing short of stunning.
through brute electrical and mechanical force, these phones have melted/transformed into possibly the silkiest and most holographic ear pieces i've yet worn. the bass is so lucid and elastic it sends shivers up your spine.
they're not exy phones, and i love a good experiment, so i'll keep it going another few days.
so, when i think of burn in, i'm not normally thinking of it rectifying such an horrendously imbalanced and nasty sounding pair of phones which are basically faulty. this may not be the case with all phones or DT150 of course.
i'm not convinced that even a 1000hr 'normal' burn in in would have rectified or even touched the issues these phones were suffering. they needed a sledge hammer.
i have my Ultrasone Pro900 arriving next week mmmmmmmmm. lets see if they can match the 'faulty' DT150
