3D Sound is incredible

By Marcelion

I bought this headphone about 2 years ago and not for one second I regret. The sound is so clear and for mixing is excellent! Anyway, after using it you can get addicted and never want to hear any song without it.


Excellent choice for all-around use

I mix live & also do some recording. Plus - I am somewhat of an audiophile. I was looking for a pair of closed cans that would work well for live mixing, recording, and critical listening. Unfortunately, the best-sounding cans are usually open designs, and they don't have any isolation. The better closed designs 'usually' don't sound as good as the better open designs. In the past, one typically had to sacrifice sound quality for isolation. The Ultrasone PROline 650s have changed this.I've had mine for about a year. I use them for live mixing, studio work, and critical listening. I even use them for listening to music at the office - although my player will just barely drive them adequately. There may be a few better-sounding cans out there - but they're all open designs.Note: These cans need some break-in time! 24-48 hours should do it. If you don't believe this (I didn't), then listen to your favorite reference material through them right out of the box. Next, break them in by connecting them to a source of your choice at a moderate volume level - and let them run for a day or two. Listen to the reference material through them again.The PROline 650s are the best-sounding closed cans I've heard to date (though I have yet to listen to the PROline 750s). Their response is very flat & true. They have the best imaging of any cans I've heard - closed or open. Plus, they have an extremely detailed sound, yet they're not harsh. They will reveal any shortcomings in your source material and/or audio chain. The 650s are ruggedly built, and they have decent isolation from external sounds. The detachable cord is nice - as is the fold-up design. The ear pads are user-replaceable, and a spare pair is included. A short coiled cord & a long straight cord are included, as well.In contrast, they're not the most comfortable cans I've owned. Although they are more comfortable than many of the other closed designs I've worn, they can be somewhat uncomfortable during those 6-hour listening sessions. I've certainly seen better-looking cans, but then again - I don't buy audio gear based on aesthetics. More importantly, I have found that they're not the easiest to drive. A few of the consoles that I do live mixing on don't have enough headphone output to properly drive them. Some portable audio players & recorders may also have trouble driving them adequately. Of course, any decent headphone amp will solve this problem.Summary: Pros: Sound quality; imaging; isolation; ruggedness; detachable cord; fold-up design; spare set of user-replaceable ear pads; comes with a long & short cordCons: Long-term wearing comfort could be better; aesthetics; not easy to driveConclusion:If you're looking for a pair of cans that will work well for live mixing - yet have the sound quality required for critical listening & studio work, the PROline 650s are an excellent choice. Keep in mind that you may need an external headphone amp in certain situations. Aesthetics are not the PROline 650's strong point.


Then again, I think I'll just keep it.

I just wrote a review saying it didn't particularly like these phones. They won't let me delete it, so I'm updating it here.At first, these phones seemed a bit flat and lacked clarity. After spending an afternoon listening on a better quality stereo with a variety of music, I like these much better. They are flat, and it takes some getting used to. But if you're like me and are constantly trying to figure out the best level for low end frequencies on your mix, these are an indispensable tool. Get a pair and remind yourself what music was intended to sound like before you pumped the lows to feel it and boosted the highs to bring definition out over the road noise.

I've been looking for pair of cans for while that will give me clear, clean and accurate sound for recording a live mix, I've tried sony's, yamaha's, shure's and akg's but my recordings always sounded different from the mix. I found the proline 650 on sale here so I decided to try them, and WOW, I do not regret this at all. These headphones reproduce every detail, good and bad, clear, clean and accurate. I've also been using them for my leisure music listening and what an improvement. The downside is that they are meant to be used with pro equipment, so if you want to use with lesser quality devices like mp3 players, computers, etc, you will need to use a quality headphone amp to enjoy them.My only wish is that a 1/8 - 1/8 cable was included instead of the clunky adapter.
