Everyone who is into headphones surely has heard of the German Sennheiser. Sennheiserhas been active for over 75 years and they are one of the most respected companies in audio. Recently its headphone division was acquired by the Swiss Sonova group, and that’s starting to show.

Now this is where it gets interesting because aside from the differences in isolation and comfort performance and the associated sound signature changes with each material, they are also designed to work in tandem with the nozzle’s dual-fit system. The highs are not tuned to bombard you with details and upper-harmonics, so if those are the priority – the IE 200 will disappoint. If you appreciate natural-sounding highs, these will align with expectations. Soundstage and imaging

The memory wire near the earpieces is another annoyance. Sennheiser’s choice of malleable wire has its pros and cons (e.g., constantly bending out of shape), and the latter outweighs the former for me. This particular cable is also very prone to touch noise. Personally, I like to pair the IE 200 with IFI Zen Dac V2 without bass boost enabled on the DAC-AMP. For on the go, I use it with the LG G8X which also sounds great. Sennheiser states that “the IE 200 can appeal to a variety of listening preferences thanks to its unique dual-tuning feature – from deep and emotional bass response to texture-rich treble presence” . Giving it 3 stars because of the ear tips provided. They are not good and finding a fit is extremely difficult. Had to switch to ones provided by Kato which worked perfectlyOne very subtle design aspect that you might miss when first using the IE 200 is a small vent towards the top of the nozzle. This is part of the tuning system that works in tandem with the ear tip positioning. There is a more obvious additional vent on the front plate to allow the dynamic driver to breathe. The IE 200 nozzle itself is a bit short but the extended L-shaped housing does add some additional penetrative depth so you can get them quite close to your concha basin and with the right tip you can improve both the fit and seal further. BASS: Fantastic! Mindblowing! Extraordinary Dont know what word needs to use. It's pure, Instant, and, loveable. Really can't express it in words but truly love the bass in IE 200. Become a fan of this bass. A very warm welcome! Sennheiser, to the entry level space of audiophiles with the IE 200s. It’s an addition to their existing IE series lineup of IEMs IE900, IE 600 and IE 300. Let’s have a look at it closely in this review. The IE 200 intend to change all that. They are priced competitively, utilize the same driver platform as the flagship IE 900, and measure remarkably well.
