The first PX100 was one of the original Sennheiser mobile headphones that revolutionized portable listening, delivering sound quality previously unheard in the category. Now comes the freshly updated Sennheiser PX-100II-i model with 'built-in' iPhone / iPad microphone and Apple player controller on cord. Expect nearly the same level of audio performance that made the PX100 amongst the most desired smaller cans in headphone history, along with all the new features your modern on-the-go lifestyle demands.

Product Features:

  • Built-in microphone & Apple player music control
  • Fully folding, collapsible design for ease of transport/storage
  • Open-back earpieces allows listeners to remain aware of surroundings

What's In The Box:

  • Soft-sided travel & storage pouch


It seems pretty much a no-brainer to make one of the most lauded open-back portable-use headphones ever released Apple-player compatible -- so Sennheiser has wisely done just that with the PX100-IIi model. Featuring a 'built-in' microphone plus the de-rigeur 3-button call control and music advance/ skip/ volume features on cord, the PX100IIi keeps basically the same clear, rich music reproduction of its non-mic edition. Naturally, the addition of mic + control housing takes a tiny hint of detail and resolution out of the upper mids and highs, but that's likely a small price to pay for the convenenience of not missing that critical call when you're out & about. The PX100IIi open-back 'on-ear' earpieces offer no noise-blocking or isolation, but does allow listeners to remain aware of their surroundings, often a huge plus on hectic city streets or in situations where you don't want to be shut off from the rest of the world. The built-in Sennheiser-quality mic receives and sends your voice clearly to the recipient while the incoming call & speech definition remains clean and intelligible.

The Sennheiser PX100-IIi portable iPod/iPhone headphones come in a nifty all-black matte color encasing a very lightweight aluminum headband. The headphone cord extends approximately 5 ft, the perfect length for mobile or portable listening, and terminates to a 3.5mm (1/8") 'mini' plug jack suitable for audio connection into any mobile source like MP3 players or laptops/notebooks. A Sennheiser soft-sided carrying / storage pouch is handily provided in the package. The free 2 year manufacturer's product warranty covers most any eventualities with this high-quality, well-engineered 'headset' headphone as long as your vendor receipt shows original purchase via a verified 'Sennheiser-authorized' dealer, like us here HeadRoom ~ since 1992!

No match for the original PX100
Posted by Tyler from Houston, TX on 2013-04-27

Recommend Product: No
Pros: iOS Control, comfortable, nice aesthetics
Cons: sound quality, cost

I'm an avid runner and have been exercising in the original PX100's since around 2005. In my opinion they are the perfect workout headphones: sound quality, situational awareness, comfort, durability.. all superb.

I ordered a set of these because my PX100's had developed an issue with the cabling after all these years. I'd read the negative reviews of the PX 100-II and knew they might not be my cup of tea but I figured it was worth a shot to see for myself, especially because the iOS control on these is a major plus.

Unfortunately, these just can't hold a candle to the original. Too dark and bass-heavy. On the whole, these are decent cans and had I never used the originals I'd probably rate them higher but really to my ears these sound more like the Koss KSC75 than the original PX100. The KSC75 are an amazing bargain for 20 bucks, but I've always found them a bit boomy and lacking the clarity and separation of the PX100. Sadly, I would say exactly the same thing about the PX100-IIi, and these cost much more than the $20 KSC 75, not to mention that they cost $40 more than I paid for my original PX100.

I ended up returning these and spending $75 to have my original PX100's recabled with an inline iOS connector, now they are better than ever!
