I'm an on-ear open junkie, so this high praise says a lot about the PX95.  A list of on-ear opens I have in various drawers:  AKG K403, PX100-ii, PortaPros, Jays V-Jays, SR-80 and some more that I can't remember right now.  My current favourite is the PX95.   Finally, an on-ear open that actually has decent bass extension without the PortaPro's boominess.  There's no Sennheiser "veil" or "mid-bass hump" here (wow!), so this is closer to the PortaPros than the PX100s.  Mids are decent - few on-ear opens screw those up, but what you trade in for your...

General Review Unfortunately not the be-all-end-all. After seeing and hearing the MM450X at the Frankfurt Airport I though it had it all and could do it all: Bluetooth apt-x, noise cancelling, bluetooth headset, wired passive, talk-through, compact and foldable, easy to recharge, and with decent sound. After some ownership i've found that it's a bit of a compromise and the perfect do-it-all is still yet to be made.   Features: Gadget-wise the MM 450-x has it all and performs. Apt-x is noticeably better than standard aac A2DP. Headset microphones...

Pleasant overall. The bit of extra bass extension should please most but is not boomy.  Strong details and depth which might even be a bit harsh in the treble.  Great for orchestral.   Worn over the ear only so no microphonics.  tri-flanges isolate well, but can be generally difficult to insert and uncomfortable due to the wide nozzle.  Memory wire could be annoying.  Everything should come with a case like this.  Not a huge fan of clear, but secret service wanna-bes might.

Detailed highs are slightly noisy, no soundstage at all,  thumpy, boomy bass can be annoying and mids are weaker.  Definite V profile w/ sibilance.  Excellent for Sci Fi movies! Minimal microphonics - none when worn over.  Great accessories - bi-flange works great and metal body is a nice quality touch.  Can be a little hard to remove.  Covering the rear ports fixes the boomy bass which making the mids/highs muddier.  Basically a sonic disaster.

Very nicely balanced overall. Bass very slightly lacking, but this is a matter of taste.  Lots of tips to choose from, and came with foamies!   Cheaply put together though.  Loads of microphonics.  Clip is useless.  Thought I heard some imbalance but it went away with burn-in.  Questionable quality?   After further burn-in, my Betas became very bass dominant, though still with excellent overall sound quality.  I wouldn't buy the Betas again.  Sent back to Hong Kong for warranty and I sold the replacements.

Just generally good and hard to find fault with.  Not really deep low bass, but enough to be pleasant.  Mid-bass has good presence and there is excellent clarity and detail in mids and highs. I found soundstage to be a little congested and overall a bit of a "thin" sound.  While many people have praised these, I find them a little boring to listen to.  The highs do not have an audiophile-grade "zing".  Clamp force a bit high at first and ear pads could be more comfortable.  A little more closed than semi-open so soundstage is not that wide. While...

Awkward fitment, but pleasant sound.  Good control of microphonics, even without wearing cord up (only really one way to wear it).  R Ch lost trebel after 10hrs of burn in!   2nd pair.  These don't isolate that well, but super wide soundstage, great detail, and suitable amount of bass that extends well into the deep.  Very fun to listen to. THese are definitely mid centric, maybe even bordering on bright.  Bass, as said before is there, even with a good seal, maintains its backstage presence.  Mids and treble are clear with great detail and...

Got these as a gift, sold them for $20 to someone who wanted noise cancelling.  I warned them that the noise cancelling wasn't very good but they still wanted them.  This will cancel an HVAC fan, or some traffic noise outside your building, but that's about it.  These aren't Quiet Comforts, nor are they IEMs.  These cancel noise like a shallow IEM with the dynamic range of a cheap ear bud.  If for some reason you really want an on-ear headphone, not IEMs or over-ear, go with a Philips model that has memory foam.  Frankly passive noise isolation is...

A long time ago it wasn't as easy to find a decent set of discount headphones and I didn't know about head-fi so I got these just to test all the stereos I was working on.  These were my first circumaural headphone so I'll always remember them for that.   These are somewhat big cans, but very isolating. Sub bass seems to be missing as there's no "rumble" to these.  Vocals are unclear, messy, muddy.  Rest of the range is good but very closed.  Highs could use a bit more detail, otherwise well balanced.  Mechanically these are a disaster.  The...
