Summary: Despite a slightly uncomfortable fixation we get good sound if you follow two rules – choose tips correctly and ensure that your source does not provide too heavy a sound.
From the abovementioned you can realize that I observed these rules. I cannot guarantee that you will be equally lucky. Beware of quick listening with an awful sound source. Understand that IE8 can be easily counterfeited, which is often practiced by Chinese manufacturers.
Conclusion: What a rollercoaster ride… first they sounded like the IEM-equivalents of the Ultrasone HFI-780 or Beyerdynamic DT770, or something like the Phonak PFE with additional subwoofer. Now they sound like the HD 650, like the Atrios with a decent tweeter, or the RE0 on steroids. Makes no sense to you? Well, get in line.
Pros: Rich, cohesive sound with realistic bass, precise midrange, and natural treble – one of the best sounding universal-fit IEMs, Very good build quality, comfortable to wear, User replaceable cable with excellent build quality and low cable noise, Sound character changes over time – if to the better or worse is up to one’s personal preferences
Cons: Low noise isolation for a high-end IEM, Huge but sub-par selection of included silicon and foam tips, Useless bulky aluminum case which adds to the IE 8’s price
Summary: Keep the world out and the sound in with the most powerful isolating earphones we’ve ever tried. One word of warning: crank up the low end too much and you may enter a parallel universe composed of pure thundering bass.
Excerpt: Sennheiser’s IE 8 ($449.95) is the firm’s flagship in-ear headphone and it’s a product I’ve wanted to hear ever since I got an introduction the IE8 and IE7 models at a Sennheiser tradeshow booth well over a year ago. At the time, the booth guide explained that while the second-to-the-top-of-the-line IE 7s and top-of-the-line IE 8s were both intended as top-tier performers, the IE 7 offered—deliberately—slightly brighter or more “treble rich” tonal balance overall, while...
Summary: There are many positive elements engrained in the Sennheiser IE8... for example the first impressions are superb due to the fact they have some of the best packaging around. The product is as well protected as it could possibly be and the wealth of information on the box is first class. It is also good to see that Sennheiser offer a 2 year warranty with the IE8.
Summary: The IE8s are a very interesting set of in-ears, because they combine a lot of different features sound wise. One of the things I really love about the IE8s is their expansive sound stage, it is quite simply the best I have ever heard from an IEM design. This makes them incredibly entertaining to listen to because the presentation is very life like, not completely left / right like with some in-ears.
Pros: Sound quality, Adjustable bass, ranging from plenty to insane amount wise, Midrange, Sound stage, Ergonomics, Cable solution handles microphonic noise very well, User replaceable cable, Good tip selection, Good bundle, Durable
