The hugely successful Sennheiser HD25-1-II headphone remains a professional-oriented, sealed 'on-ear' model offering excellent sound quality performance and unique headband versatility. The proprietary construction makes it a superb choice for active listeners wanting durable headphones that stay where they need to be no matter how intense the jams. The Sennheiser HD25-1-II is also a great candidate for music-loving commuters, airline travelers, gym rats, DJs, studio pros, beatmakers and producers working mixing desks, computer-based audio interfaces and analog/digital recording consoles -- or just block-rocking the iPod. The HD25-1-II sonic signature: Well-defined lows with a tightly damped sound in the bass; very even-sounding mids, nicely present and transparent; and smoothly extended uppermost highs. Now in the Sennheiser line-up for two decades, the HD25-1-1 remains one of Senn's top flagship 'sealed/closed' category headphone and its no wonder why; it's an extremely well-engineered, road-worthy headphone ideal for everything from audiophile iPod portable listening with 'lossless' files to acoustically demanding studio work to killer office cubicle 'phones and it capably delivers impressive sound quality anywhere you want your tunes.
Although it will highly benefit from a headphone amp when used with any portable audio player, the Sennheiser HD25-1-II should still deliver usable volume levels with most iPod, iPad, MP3 players and computers even without a dedicated head-amp -- although chances are it may sound a bit 'flat' and un-dynamic when used directly from some portable sources. The HD25-1-II is well-recommended mobile choice for those willing to invest a bit into pleasurable high-quality listening with a portable head-amp providing maximized detail resolution and great musical punch.
The most unique feature of the long-running Sennheiser HD25-1 model is the headband that surrounds the head almost like a hat brim. An effective and comfortably ergonomic headphone, you can easily wear the HD25-1 over a baseball hat or even our neat-o HeadRoom employee beanies with a propeller on top! The HD25-1-II's unique 'split-headband' comes from studio applications where a secure fit is critical; it's amongst the most stable headphones we've worn during serious head-banging or while pulling sick disco-fever B-Boy dance moves around the office. The mid-sized 'supra-aural' (on-ear) earcups also swivel out of the way on the left ear so you can hear ambient sounds or perform fast-paced 'mono' DJ mixing with one ear. The band construction is a sturdy plastic composite material that feels well-built and durable. The earcups are padded with a supple leather-type material and offer respectable ambient noise attenuation. An extra set of 'soft' fabric replacement earpads is provided in the HD25-1-II packaging along with a handy transport carry-pouch. The short detachable 4.5ft single-sided, straight Y-cable eliminates dreaded cord tangling when listening on the fly and the plug terminates to a 1/8" inch (3.5mm) mini-plug. A full-size 1/4" adaptor plug is handily provided. A 2-year manufacturer's product warranty remains standard with all Sennheiser headphones with your HeadRoom 'authorized dealer' purchase receipt.

Recommend Product: Yes
Pros: light weight, built like a tank, sound amazing
Cons: can be uncomfertable after a while
I only have one con on these and it's that they can become a little uncomfortable to wear after a while. This isn't too bad though because I can generally just adjust the position a little and be good to go for another hour or so.
So yes, I highly recommend these headphones to anyone who wants a great pair. It's just my opinion, but I'd say these are probably the best sounding set you'll get for up to the $350 area.

Pros: Wonderful sound reproduction. Good isolation, Value and erogonomics in a working atmosphere
Cons: The fit takes some getting used to
I actually fell in love with these headphones at CanJam 2010. Up till this point I was driving the phones with my ipod. I had read some reviews and an amp was recommended so I was on a mission for an amp. After many amps and comparing these phones with the best of the pack I can honestly say that they hold there own with the bid dogs when they have the right source and amplification. They have nice bass response and the highs were no longer overpowering. Overall I would say the sound spectrum is very well balanced.
There isolation is great when I use the phones at work or play. They stay on your head what ever activity you participate in, and when someone is trying to speak with you, you can easily pull them off to one side and listen. They have a rugged build and I suspect they will last for many years no matter what your activities are. Parts are readily available and the phones have a very simple construction so they are easy to work on and modify if you so desire.
Final thoughts. These Great little phones don't come alive until they have been burned in and are given a good source and amplification. The fit takes a little getting used to so give them some time.

Pros: Detail, highs, mids, comfortable, cord
Cons: bass, small soundstage
Previous experiences, HD238, HD555, HD595, HD280 Pro. The 595's were the closest thing to be a forward headphone.
I finally pulled the trigger for these. My initial impression was the earpieces will fall off. They are a bit loose, but trust me they are firmly fastened. I really liked the cord. Not because it's the greatest sounding cord, but it's flat and very durable.
Now for the sound. I really like the sound of these. They are sooooo much more forward than a typical Senn sound. The highs are nice and crisp with a good deal of detail.
Mids are very strong. They really shine bright and voices sound more realistic. When I put them side by side with my ES7, the Senn's sounded much more natural. As if I was listening to someone talking to my face and not through a headphone. These are great headphones for instrumental rock. Satch Boogie baby!
Bass - I really like the bass on these cans. I did list them as a con, because the bass is very tight and very detailed but lacks a good deal of ooomph. Again, when I put my ES7 on, the bass hits with much more authority. So if you like sub woofer type sound, you might look elsewhere. That said, the bass is pretty solid and like I said is detailed. Just not enough for my taste.
The soundstage is also very narrow with these. Perhaps not the best for orchestra type music or live music that is recorded with a really wide depth of field. You won't get the experience you're looking for. The lack of soundstage perhaps is what makes these Senns more up front and personal. Definitely over any other Senn I have owned. Granted, they are not open back cans either. But I find them more upfront than my HD280 Pro.
They will do just fine out of a portable player, but a small amp will really give you the detail you would want. As for comfort, I listened to these for many, many hours on end when I first got them. I had several plane rides the day after I got them and they are very comfy in deed.
Oh and I should mention, for an on ear headphone, they do a GREAT job blocking sound. Would have never guessed that one because the earcup is pretty small. Not much bigger than the 238.
Anyone who likes a small durable headphone with really nice detail should grab these up. As long as you don't like the feel the air of the sub bass hit your eardrum, you'll be fine.
