Compact housings offer a secure fit and long-lasting comfort. Adjustable ear hooks adapt to your ear shape, giving a natural and secure grip. For the perfect fit, the IE 600 comes with six pairs of earbuds. Small, Medium and Large silicone tips are matched by the same sizes in memory foam. These precisely adapt to your ear shape, giving excellent comfort and outside noise isolation.

Whereas the A8000s invariably compel attention, delivering everything all at once in a manner that excites and occasionally overwhelms, bringing music to life with unrelenting, unwavering energy. Everyone who is into headphones surely has heard of the German Sennheiser. Sennheiser has been active for over 75 years and they are one of the most respected companies in audio. In the past years, Sennheiser has positively surprised us with a lot of top-quality products such as the HD 800 (S), the HD 660 S, the HD 560 and several other HD 5-series headphones. Sennheiser has also been active on the IEM and TWS market and the IE 300, IE 900 and Momentum True Wireless 2 score very well there. Microphonics is low but not aftermarket cable low. There is a little bit of travel from taps below the splitter but nothing that annoying. It’s probably a testament to the decent level of isolation that you can hear microphonics at all from the IE 600.

The IE 900’s tuning is the most reference, neutral and balanced. You get a wider presentation with more air and spaciousness making the IE 900 sound less in your head. The level of clarity and precision is elevated compared to the IE 600, making it a typical high end tuned, lighter bodied IEM. The IE 600 uses a detachable cable format which for the original IE 800 users is a bit of a godsend considering their former flagship had a fixed para-aramid reinforced cable design with a 3.5mm termination. The IE 800 S, however, did go some way to fixing that by making the cable detachable. vs moondrop s8 : ie600 has better sub bass rumble, more energetic treble and less shouty midrange, s8 has more noticable ba timbre, more shouty and forward midrange, better separation, resolution are about the same I really do suggest listening to the IE 600 in balanced mode, as it really performs better. You get the best technicalities, with more note extension, airier mid and treble presentation and a wider soundstage.

The 3.5mm SE "para-aramid reinforced" cable looks and feels the same as the much-derided IE300 cable, and the IE600 also comes with a 4.4 balanced cable of similar construction. (The para-aramid family of plastics includes Kevlar, but perhaps for trademark reasons Sennheiser doesn't use the word.) The IE 300 has a more U-shaped sound signature but it to me in the graph looks more extreme than it really is. The bass is impressive and addictive, the mid timbre is to die for and the treble is energetic. It’s just an easy end engaging IEM to listen to, no matter the music you throw at it. Since I received this unit from my fellow audiophile Pulkit Dreamz, I am grateful to him. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else.

Great art challenges our assumptions and asks questions of us, so I ask this – what makes an earphone great? Considering the cable changes and volume matching it would require, I'm not set up for any detailed comparison of SE and balanced. Perhaps someone else on the tour can do that. Inside each tiny, lightweight (4g) housing, Sennheiser has found room for a 7mm ‘TrueResponse’ transducer to do the audio business. The company is adamant that a single, full-range driver is preferable to the multiple-driver-plus-balanced-armature alternative many self-proclaimed ‘high-end’ alternative designs utilise – as long as it’s properly implemented, that is. Given that Sennheiser is claiming a frequency response of 4Hz to very nearly 47kHz, its assertion that the driver fitted here is ‘full range’ seems difficult in the extreme to argue with. And given that Sennheiser is claiming the most accurate channel-matching and the lowest unit-to-unit variations anywhere in the industry for its drivers, thanks to a manufacturing operation that includes precision cameras to monitor the process, ‘properly implemented’ seems to be covered too. During these two weeks, I haven’t used the IE600 exclusively as other things need to be reviewed, but I did find that, apart from the exclusive use for 4 or 5 days, that any time I felt like listening at other times of the day, I reached for the IE600. That is already something that goes to prove my very positive experience with these IEMs. They are not perfect, I will get into details in just a second, but I still feel that the overall sound of these IEMs is very very good.

While I am not going to go into a full review, I can safely say that these are one of the finest resoluting IEMs and the soundstage better than the Shure IE 846s that I have owned for last 6 years. This is a variant on the similarly-sized 7mm driver inside the IE 900, though that particular one is titled, X3R TrueResponse, which uses a three Helmholtz resonator chamber design.There is no like-for-like replacement of the IE 800 given the new nomenclature with numbers above and below but some are suggesting the IE 600 might be the closest, we shall see.
