These headphones that folds on itself is very stylish and practical. Beautifully made, the flat cable seems resistant to the assaults of modern life! I used it with an iPhone and it works very well (without pb conversation with a good rendering of the word). The only downside is the sound quality when listening to music, one would have hoped for greater precision in the treble (like the Koss porta pro). For the proposed sum, it remains a good-value price, however!
