Nice compact folding design and excellent noise-cancellation sound quality! Just what needed to enjoy music in a noisy background.
I got this for a friend, and this was his review: Superb quality for its price point! Despite being "bass" headphones, the upper and mid frequencies were not drowned out making the 450bt quite a versatile unit (great for Edm/Hiphop, performs decently on acoustic/jazz tracks). Very comfortable headphones even with spectacles on.
The sound of HD450T is overall balanced and clear. Like the white colour. The pressure on the ear builds up with prolonged use (more than 2 hours), though. But generally quite satisfied
