Sennheiser HD 439 Headphones
The HD439 from Sennheiser has been designed to offer a compelling and premium sound quality, while retaining a stylish design. This particular model utilises a closed-back driver design to offer a private listening experience, so the stranger sat beside you on the train or bus is unlikely to hear what you're listening to, and even more unlikely to disturb you.
These headphones offer an exceptional sonic performance, while its bold and impacting design (which includes a chrome inner lining tempered with black mesh turbines) is sure to make you feel as good as they look and sound. Sennheiser have paid special attention to the bass response of this model, ensuring a deep and extended bass with a degree of tightness that even some 'superior' headphone models struggle to achieve.
Both cables are detachable, so you're able to find the perfect length cable for your needs, while also being able to replace them - should the signs of wear-and-tear begin to take their toll. This means that replacing this cable can be done inexpensively and with ease.
