Ultrasone proline 750 vs Senn HD650

Thread Starter 
After reading some threads, I have noticed that proline 750 or 2500 and HD 650 seem to be very popular. they both fit my budget range. so need your suggestion which one should i pick? and why if possible
or is there anything you guys can recommend me?

HD650 needs an amp...

Not sure about the Ultrasone as that was originally my first choice before coming here and reading some.

The Ultrasone PROlines need an amp also, albeit one with higher current potential than the HD650s require.

Of the two you're considering, the PROline 2500s, being open, would be the best match-up for comparison with the HD-650s.

We really need more info to point you one way or another.

As others have mentioned they both need amps.

If you want harsh metallic sibilant highs, go for the PROLines. If you want something pleasant to listen to, go for the HD650.
I have owned the 2500's and I can not honestly understand what people like about them. They sounded very artificial and I experienced listening fatigue after just a few minutes.
If the devil were headphones, he'd be the PROLines 2500's.

There's my $0.02

You'll probably find the Senns more pleasing. The PROLines never even made it to FOTM status, though they come in pretty cases.

Heh-heh, guess I'm just Runnin' With The Devil!



Some people get them, other people don't. Obviously, no headphone perfectly suits everybody. Plenty of folks here prefer the PROline 750s or 2500s to the HD-650s, and vice-versa. But I'm not about to go running down the HD-650s because I happen to prefer the presentation of the Ultrasones.

I have both 650s and 2500s. I like them for their differences
and their unique presentations of different musical genres.
Classical and lush recordings: the 650 is untouchable
Energetic and detailed recordings: the 2500s are terrific.
Both need good amplification and the 2500 is a bit less forgiving of the source. If your source recording is dubious, the 2500 will clobber it. The 650 is a bit bloated and bottom heavy (unless you recable it with Zu, which makes it more like the 701s but I digress).
I kept both because they are so dissimilar and so good

Like all choices here it depends on what problems most irritate you.

The 2500 gives you a very coherent (though closed-like) soundstage that most other phones even with crossfeed can't match. In fact at the recent meet in SF, it actually took a few songs for the K1000s to stop feeling artificial in instrument placement. You heard me, even the K1000s. Most phones have a L/R linear soundstage. The 2500s (less so on the 750s) are much more spherical, and once it takes it's difficult to go back to a more traditional soundstage. The difference is nearly as much as going HD650 to 2500 as RS1 to HD650.

That said, technically the Senns win on many more counts. I'd judge it the superior phone. If I had only one phone it would be a Senn... but the Ultrasones are getting much more listening time in my home.

I've never heard the Proline 750s, but owned the 2500s and own HD650s. I sold the 2500s and kept the 650s (my first love). I had difficulty with the upper mids and highs of the 2500s, but I really miss the way that headphone does the bottom end. I agree with Blessingx's comments on source. My 650s have been through lowly to humble to dang decent sources and always sounded good to me (just better with upgrades). The 2500s sounded horrible with an ipod (nicely amped) and a decent PCDP, but like completely different headphones through an Exemplar modded Denon 2900. In the end, the HD650s won out for me as an overall great headphone, but I miss what the Prolines do well.
