Excerpt: These headphones are the most phenomenal sounding ever. They are super comfortable, lightweight and durable. The construction on these headphones is utterly amazing. The ceramic housing that contains the driver definitely is ultra durable. The product description says that it is scratch resistant. Also the cabling is an ultra high quality kevlar material.The case that is included is leather with a magnetic closure.
Pros: Comfortable, Compact, Durable, Good Bass, Good Value, Great Sound, Lightweight, Stylish
Summary: I'll keep this short cause I'm not good at writing reviews.
I just wanted to say that I have tried Shure 846 and I really did NOT like it. The sound from Shure is too condensed with not much soundstage (unlike its full sized cans which sound very nicely!)
These IEMs (IE800s) are the ONLY IEMs that I've tried which sound like a full-sized headphone. You can't go wrong with the sound quality!
Pros: Amazing SQ, Excellent soundstage, comfortable to wear, small, light, built like a tank
Cons: Cable makes noise, cable is not replaceable, limited eartip selection
Summary: The IE800 are the best IEMs I have ever tried. This includes the Shure SE846 & 535, Audeo PFE232, AKG 3003, JH13 and JH16 and many others. I also prefer their sound to many full size cans like the beyerdynamic DT-880, T70, T90; Sennheiser Momentum, HD650; Shure SRH1840 etc. The closest I've heard to the amazingly balanced sound of the IE800 is the LCD-2 rev 2, which I also own.
Summary: I'm not that much of an IEM guy. That said, I needed some IEMs as I sometimes travel. I wanted a good all-rounder, something with which I could listen to music on my phone and also play games on PS Vita.
I didn't want some "decent" IEMs though. I had those (Sennheiser CX-300 II, Audio-Technica ATH-CKX9IS) anyway. I wanted the best IEM out there. I've tried two that are said to be the best, Shure SE846 and Sennheiser IE800.
Pros: Amazing all around sound, superb bass, mids and treble, cool and modern design
Cons: Nothing for me. Non-detachable cable might bother some.
Summary: After reading glowing reviews of both of these in ear monitors I was still unable to decide which one would be right for me so I bought both, first the Shure and a few weeks later the Sennheiser. I already own the JH Audio 16 Pro, Ultimate Ears Triple.fi 10 Pro, HiFi Man HE-500, Sennheiser HD 650, Shure SRH940 among others. My music files are all in FLAC format and I play them through an Astell & Kern AK120 and also used a Samsung Galaxy S4 for comparison purposes.
Pros: Amazing soundstage, incredible detail, deep impactful bass, very comfortable even for long periods, easy to drive, sound good even at low volume!
Summary: Love them. Read a number of reviews and it was between these and the Shure se846. The Sennheiser's went on sale and I jumped right on them. The only really complaints I read about was about cable length and microphonic noise. To me cable length is fine I use this in a completely listening mode I.e. sitting in a chair and/or on a airplane or even in bed. No Microphonic issues.
Pros: Size Kevlar cable Sound quality
Cons: Noise isolation on plane ... again very minor issue. Didn't like case that came with it ... too big. I'm using a smaller case that came with my older Westone's that way I can carry in my pocket.
Summary: I have the Sennheiser IE80 but wanted to try the IE800 to see if they were really all that much better. As it turns out they are. The IE800 has a smooth balanced sound signature from the base to the highs. The sound is 'clearer' than the IE80's as well. I love the fit, too. They are very small earphones, and can be worn all day without any concern for fatigue or discomfort.
Pros: Smooth and balance sound; excellent separation; small and comfortable
Cons: Cord a little short; cord microphonics noticable when moving around
Summary: Excellent top to bottom, ultra-smooth with no peaks, dips, or roughness. Strong bass and treble, but very high quality. Some IEMs have difficulty producing the very deep bass below 25 hz clearly - the IE800 does it with ease. Most comfortable IEM I've ever used.
