Amazon.com: SENNHEISER Pro Audio In- Ear Audio Monitor, IE 400 Pro Clear : Musical Instruments

Best iem, in ear monitor head set for around mid 300$. Compare with my old over ear monitor head set audio Technica M70x ($300) the ie 400 pro surprisly pick up more details. Bass is more impactful then M70x, but not over it. M70x feel flat in high to end and that it is why I bought it as a monitor headphone to use for editing sound.Ie 400 pro have warm and natura breathing sound. It surprise me a 7mm single dynamic can pickup more details then my over ear monitor headphone.And I don't feel it when I'm wearing it, it is so light, and ergonomic design.

Classic sennheiser sound,no distortion,open ,airy, excellent bass, low fatigue. These make pretty much anything sound really great including listening to compressed audio files. Be aware that the quality of your player and music source will still greatly effect the experience. My LG v40 sounds incredible playing the same files when compared to my pixel 3a. The reason I'm only giving 4 stars is because the upper range,namely vocals, just don't give me that 3D experience that I like. The highs sound really nice,nothing brash,super smooth,but I just don't feel like I'm at the show. All that being said, these are great headphones and I'm super happy with them but I feel like they not worth the money. I feel bad saying this because I love sennheiser and will continue to buy their products but I want to be pleased with every aspect of the sound for a price tag of $350. Close but not quite there, perhaps the new IE 300 will suit me better.

Many complaints about earbud sound quality are due to poorly chosen OR poorly designed ear tips. Every ear canal is a little different and getting the fit that fills the ear canal and holds the bud at the right angle can make a HUGE difference in hearing music well across the full human hearing spectrum.If the canal fit is poor…the sound is often horrible and your money is wasted, because of something you can generally fix. It’s the Ear Tips Dude!Higher-end earbuds address the need for a great fit in a variety of tip designs to give the best fit. Try them out! This Sennheiser product uses memory foam and that works well for me, BUT it took effort to find the right match for Each canal. Yep. Human bodies are kinda symmetrical…at best.

Sennheiser is a well respected long established quality brand that has a reputation for a unique sound. Unique sounding products are rarely uncolored, and the stereotypical Sennheiser sound is usually characterized as the "Sennheiser Veil", which is gently rolled off from the upper midrange to the high treble.For the IE400 Pros there is simply no family resemblance, to the extent that the stereotype still applies to the brand at all. The IE400 Pros are about as neutral and well balanced as any IEMs I've heard, without being clinical or threadbare. Bass is remarkably deep and taut conveying the classic rhythm, timing and pace virtues better than most balanced armature competitors, while having the warmth and solidity that most BA based drivers lack. The mids are neutral and transparent. Voices are natural and present in a vivid but natural presentation that simply is honest. The upper octaves are clear, present and appropriately sparkling.After a series of Balance Armature based IEMs, listening to a dynamic driver based IEM of this quality is revelatory. The IE400s are simply more cohesive and seamless than the multiple crossover BA IEMs, probably due to the complexity that those designs require.These are monitors in the sense of having a remarkably flat and neutral tonal balance. These transducers are transparent to the source, which could lead to some bad impressions if demoed with poorly recorded material or lossy sources, but they are startlingly realistic sounding with good material played back on good gear.I've owned headphones from Stax, AKG, Beyer, Shure and all the rest of the usual suspects and found no IEMs that are as completely satisfying as these IEMs. Emphatically recommended.
