The formidable Sennheiser HD 650 headphones are fit for a king--and have a price tag to prove it.

Sennheiser's flagship headphones have high-tech styling; extraordinary bass response; and an extremely comfortable design.

They're heavy and very pricey; not to mention ill suited for use with the iPod.

We approached Sennheiser's top headphones, the HD 650, with high expectations, as word of mouth for the product has been overwhelmingly positive. The headphones certainly look the part; the HD 650s' luxurious feel, the thickly padded headband and ear cushions, and the titanium-silver finish leave no...

High-tech styling; Extraordinary bass response; Extremely comfortable design

They're heavy and very pricey; Ill suited for use with the iPod

These are not cheap headphones. They are reasonably expensive but you will more than get what you pay for.

Amazing sound; all day comfort; value for money; cord length

Makes your other headphones sound bad; need an amp to get the most out of them

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".

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.

An unusual feature of the Sennheiser HD 650 headphones is that the cables can be unplugged for easy replacement should the conductors ever fracture under physical stress in future years. They are quite thick cables, too, and three metres long, terminating in a 6.5mm plug.

Superb no-compromise sound; Very comfortable to wear; Main plug is 6.5mm; replaceable cable ensures long life

Sensitivity too low for some MP3 players

The Sennheiser HD650 has been around for a while and has certainly achieved a high reputation among both domestic and professional users. It's a smart, no-nonsense model with oval earpieces which seem to fit snugly on every head we tried.

A stunning piece of kit that'll bring the very best out of your CD collection

Incredible sound quality whatever you throw at them; great build quality

Pricey; only for hi-fi nuts

I was like a lot of audiophiles starting out. I had a below $100 pair of headphones and thought it couldn't get much better than that. I looked at headphones like the HD650 and thought their pricetag, which is a hefty sum to most, couldn't be justified.

High-quality warm sound signature; Good imaging; Comfortable; Replaceable parts

Not the best build; Clamp is too tight at first; Not for trebleheads or bassheads

I got these on craigslist lightly used (I think he said like 40 hours of use or less) in the original package and original everything and in perfect condition for $250. Half off is a blast. If I didn't get this good of a deal I would have got the HD 598s.

These are 300 ohm headphones so you need a headphone amplifier that is a given; Luckily, my MSI Gaming 6 has 2 headphone amplifiers built in and can handle 500 ohm headphones; I had the Oppo PM3 planar magnetic headphones before this.

These do feel a little fragile, so for $500, they should maybe have a little higher build quality, but I doubt I'll break them; Maybe that is why these are so awesomely light weight; Just be careful
