The sound is amazing and the comfort is superb. I was not expecting that they were designed to allow the listener to hear through the earphones to what is going on around them. This is perfect for me and means I can wear them for extended periods of time and not constantly be pulling on them to hear...

Overall I am satisfied with the headphones but at the price I was expecting a little more with the materials used (just doesn't feel premium enough).

Great sounding headphones!. As we know HP are subjective to ones listening taste. Wanted a pair that were not too clinical and flat, last thing i wanted was to come home after a hard day and start an analytical listening session.

I have used a variety of Sennheiser products over the years, always impressed with their combination of form and function. These are the most comfortable headphones I have ever used, very good if you spend long hours "in the cans".

The set produces good bass, but lacks the features of other models.

Comprehensive sound and soft ear cushions make these headphones easy to wear all day

The lack of features is frustrating; and the open-ear design hinders noise isolation

Needed amp definitely and time for break in / to be accustomed with sound signature... comfortable enough..home use only as open back headphone

The Sennheiser HD650 headphone has seen an enduring popularity among audiophiles for it's high price-to-performance ratio. But for $499, how much sound is this open-back headphone packing? And is it the...

With its finely balanced, warm and relaxed sound, these Sennheiser headphones are bound to hit the spot. A colourful approach to audio never grates or tests your nerves, with the HD 650 still the standard recommendation for music fans listening to all genres and styles.

As the vast majority of online professional and customer reviews enthuse, these are fantastic 'high end' headphones, in terms of sound quality, comfort and design. However, although the John Lewis description states that they have sound insulation (like in-ear earbuds), this is not the case.

As with most higher end speakers/headphones, these need some break-in time. My initial impression was that I may have made a mistake buying these. I stopped listening to them and ran them with white noise for about 100 hours. (4 Days straight). Wow what a difference!
