I’ve upgraded my TMA1s to these and they’re now my new favourite headphones after their predecessors.
The concept is the same - interchangable parts are a life saver (the first pair lasted for 7 years and it was easy to replace the pads and cable, as well as a snapped headband in that time)
They’re built very sturdy, are light and isolate outside noise great.
Also, the sound is a lot better than the TMA1. It has enough clarity for DJing, even though they are still bass oriented (which makes sense with the DJ drivers).
