You would be suprised by how durable this product was. I bought it back in 2008 almost 12 year ago. Still this product working fine dan still kicking! Yes, it is an old product line but philips really doesn’t skip on Quality. Sound, in my opinin above average considering the price. But.yes a but, the clamping force for me is a bit much, mybe because of my big head. So it may vary for others. Overall it give me a pleasent experiance. TQ Philips
