This Philips Headphones are really very good.Pros:1. Sound quality2. Superb bass3. Built quality4. Soft cushions5. Flexibility setting on ears6. Good quality microphone7. Very good level of noise reductionCons:1. White colour bend just above the head.[As it is cloth like material, which makes it vulnerable to catch dust and get muddy]. Instead of white and blue combination i would recommend you people to purchase same headphone with Purple and coffee colour combo.2. Using this headphone more then 40 to 45 min causes heat near to ears in headphone and makes it uncomfortable to wear constantly, and also causes a little pain on eartips.
