This cans are the 414 of closed headphones, and for live monitoring use. Little, well constructed, supra-aural, comfortable and durable. Punchy sound, almost linear with a little bump in the mid-bass. Mids are good but a little "honky". Good highs but a little grainy.

Heaven! The best sealed cans I've heard yet. For me, good isolation was needed. My rig is one of the loudest out there, I'm obsessed overclocker. Great thing about HD-25 is probable the isolation abilities.

- Excellent sound isolation while keeping comfort in mind; - Natural & well-balanced sound; - Cool light design (the cans arch split for 2 parts

- Pricy - Short cord (only 4.92 feet / 1.5 meter

If your not afraid to prance around in these they are great for on the move. Completely shutting out sound with only half cups and really comfortable on the ears and light. They are really well built. I've had mine for 2 years now and quite honestly they still seem brand new.

Great sound- Bass and highs work very well; comfortable, loud

None

PRO: Very good for Djing or Studio use

CON: Not the Most comfortable Headphone but the best sounding one i have used

The look of these headphones makes them a dead ringer for the trusty HD 25 - the rounded cups, the cables that poke out of the top of them and the strange two-piece headband. If you're not keen on buying ￡260 cans that look just like ones you can snag for around ￡100, rest assured that there are a...

Superb bass slam; impact and separation; Excellent detail

Some rivals more comfortable

The Sennheiser Amperior is far from the cheapest set over-ear cans on the market, but what you get for your money is superb audio quality and a very stylish set of headphones. Definitely worth considering if you want to get excellent audio performance from your iPad or iPhone.

The Sennheiser Amperior headphones are inspired by DJ's and designed for the streets. How do we know this? Because the box they came in is covered with that slogan. However, it's a little unfair to pigeonhole these cans to hoodie wearing music enthusiasts.
