Sennheiser IE 600 Audiophile In-ear Monitor Headphone

First off, they sound real nice. They sound so good compared to everything else I've ever owned that I'm now doubting that I know anything about audio quality. I can't possibly make meaningful comparisons to other IEMs in this price bracket, so I'm going to focus on the practicalities.They are my first over ear/upside down IEMs, so I've had some thoughts about the fit. With the cable under any clothes it will tug downwards, thanks to the the ear hooks they won't fall out but it's not ideal. Either use the clip or just keep the cable out of your jacket/shirt. I'm considering a replacement cable with a mic but the cable ends up nowhere near my mouth, so I don't know how effective it would be. Initially somehow the cable would make a clicking noise with each step, a ... MoreFirst off, they sound real nice.

I'm considering a replacement cable with a mic but the cable ends up nowhere near my mouth, so I don't know how effective it would be. Initially somehow the cable would make a clicking noise with each step, a bit of fiddling with the fit stopped it. Once in I can easily wear them all day with zero comfort issues.They are shockingly noise isolating for something with a normal in ear fit. Even with nothing playing I can't hear people next to me talking. I've mowed the lawn with these, could still hear the music fine.The right angle 3.5mm cable has been great for plugging straight into my phone. Great length if you keep the cable outside of your clothes. The included balanced cable is surely overkill, don't feel like you need a new 4.4mm balanced amp/DAC to make the most of these.Only issue I've had is ironically a combination of the great fit & isolation. Since I have no chance of hearing with them in, I remove one side when someone needs to talk to me, which is slightly more finicky than a simple earbud. Then since I'm wearing them outside any clothes, the loose side falls all the way down to my belly button, swinging wildly and just asking to hook onto something. So I need to hook it onto my collar, interrupting the conversation further. This is how ridiculous I need to be to find a fault with these IEMs.

A comfortable great sounding iem with build issues

I recently purchased these only to find upon receiving them that they had a fault straight out of the box. Richer Sounds were very prompt in replacing the faulty set. The replacement set are pretty much fine. Great sounding set despite the annoyance of the far from impressive balanced cable which has a tendency of disconnecting from the right hand shell arbitrarily. I am looking for a replacement cable but due to Sennheiser making certain design decisions about cable connection it's so far proved impossible.Consequently I only use these for at home use which is somewhat limiting. In summation five stars for Richer Sound and only two stars for Sennheiser. My advice buy Chinese made iems. At least one can buy a replacement cable easily and cheaply.

Amazing IEMs. Great service from Richer sounds!

Bought online these around 2 weeks back with online store collection option.Delivery and richersounds service-Prompt updates, got immediate email confirmation of the order and estimated delivery.As soon as the nominated store received the item, store manager called promptly to inform about the collection time. At the time of collection as well the Watford store had very friendly and well informed staff. Might visit them again for a demo of speakers.About the IEMs- Can't fault these. In this world of wireless stuff, I wanted to have a look at the high end IEMs. While I own the Sennheiser's TW3 blutooth buds and totally appreciate the comfort and portabilty advantages of those, I can't stress how much resolution gets missed when the bluetooth buds are tuned to ... MoreBought online these around 2 weeks back with online store collection option.Delivery and richersounds service-Prompt updates, got immediate email confirmation of the order and estimated delivery.As soon as the nominated store received the item, store manager called promptly to inform about the collection time.

An absolute beauty inside out!

I'm lucky enough to own some of the very good IEMs and headphones ranging from 7hz Timless, Raptgo Hook-X, Fiio FH7, 64audio U12t, Focal Clear OG, Hifiman Arya Stealh, Meze 109 Pro, and Meze Elite. The Fiio FH7 and Arya Stealth have never been my favorites due to their timbre and "dry" charateristic. I love iems/headphones having an overall neutral tonal balance with a touch of sub bass and air up top. I was surprised that the IE600, at this price range, not only achievs that, but also excels in its ability to resolve music with an amazing sound stage and imaging. The IE600 can even rival my beloved U12t. It's the tight-thumbing bass and the stage that make me reach for the IE600 more than the rest. With some good recording songs, I enjoy the music with IE600 as ... MoreI'm lucky enough to own some of the very good IEMs and headphones ranging from 7hz Timless, Raptgo Hook-X, Fiio FH7, 64audio U12t, Focal Clear OG, Hifiman Arya Stealh, Meze 109 Pro, and Meze Elite.

With some good recording songs, I enjoy the music with IE600 as much as I do with the Meze Elite. Also, it's the most comfortable IEM I've ever used, and with the metal housing, it's the gem that I will keep for a long time to come. Thanks HeadAmp for your customer service, fast shipping, and competitive pricing. Now go enjoy some music!

Another Good one from Sennheiser!

Disclaimer: This is a biased preference. Please give the unit a test run before making a purchase.The Sennheiser Single Driver IEM has a V-shaped sound signature. The driver is housed in amorphous metal that was 3D printed. You get three pairs of silicone and foam ear tips (S, M, and L) in the box. You get two cables, one with a 3.5mm termination and one with a 4.4mm termination.I heard enough sub-bass rumble with a decent thump, and the bass is warm but not boomy. The highs are clean with decent air and least sibilance, but for those who are treble sensitive, they can be sparkly or harsh on some tracks.The decay of the bass is clean and does not bleed into the mids. If you like V-shaped tunes, the mids are laid back and not in your face, which may be ... MoreDisclaimer: This is a biased preference.

If you like V-shaped tunes, the mids are laid back and not in your face, which may be beneficial for long music sessions. The holographic sound stage of the IE600 impressed me greatly.The review is based on Qobuz/AM as a source via laptop onto iFi's Gryphon (using GTO filter) at +61db volume. Please keep in mind that I did not use stock tips, but rather the AZLA Sedna Light ear tips.Tracks used for this review:1. 4ware by Deadmau52. Rockstar by Post Malone3. Thriller by Michael Jackson4. 295 by Sidhu Moose Wala5. Usure Poyene by A.R. Rahman & Karthik6. Pathala Pathala by Kamal Haasan & Anirudh RavichanderWhat could have been better?1. The cable quality, which is prone to impressions even with minimal force applied for long periods of time.2. The stock tips, at least for me, were not a good fit. Although the IE600 sits comfortably and does not feel heavy during extended sessions.

Excellent detailed sound and very comfortable fit

These sound incredible. Great clarity, strong bass and pronounced but non-fatiguing treble with a warm and forward vocal presence. A decent soundstage that, while not comparable with open back headphones, is still impressive for an IEM. Imaging is excellent. The cable could be improved - it’s microphonic and rather flimsy, and the supplied case could be better quality for the cost. Overall very happy. These sound great straight from an iPhone with a dongle and don’t require a dac/amp to drive. They do sound even better with the Chord Mojo 2 though!

Really good sound, unusable ear tips

I love Sennheiser over-ear headphones. I have used 5 different over-ear headphones and loved all of them. I've heard middling reviews for their earbuds, and I gotta say the trend continues. These are my first Sennheiser IEMs and, while I did like he way they sound, I can't say they are $700 worth. And that's coming from someone with the HD 800's.What solidified my decision to return these, is the ear tips. They are some of the worst eartips I have ever used, and I'm disappointed in Sennheiser for producing such shoddy feeling ear tips for something this expensive. Obviously your milage may vary, I have small ears. But their small tips don't give a proper seal for me, and the medium tips are too big and don't breath for me. Assuming you can get a fit to begin with. ... MoreI love Sennheiser over-ear headphones. I have used 5 different over-ear headphones and loved all of them.

Assuming you can get a fit to begin with. Because the silicone tips are so thin they collapse in my tiny ears. And personally, I'm not a fan of the foam tips. I tried them, but I can't use them.I saw that some people switched to different ear tips to get a better fit, and that can work for comfort. However, the problem is that the provided ear tips are integral to the sound of the IE 600's as they are designed in a specific way to help the earbuds. If you use different tips, the low end starts lacking even more, and the highs become way to sharp for my tolerance. And even if you can find the right eartip that doesn't mess with the sound too much while still providing a comfortable fit, it shouldn't require spending an additional $15-25 on comfortable ear tips.

Superb when match with a decent amp

Just bought them with a Mojo 2, these are fantastic. They won't be run in yet, so expecting them to get even better over the coming weeks. I've been using Bose noise cancelling IEMs for some time and I've been really impressed with them, but these are another level for sure. I changed because I wanted the Mojo and noise cancelling don't work with it. I tested these just plugged into my iPhone and they were better than the Bose. But, through the Mojo and they were so much better, it was night and day. If you are spending this on IEMs, then you need to drive them properly. I would also just ask RS to price match, they are pretty good at keeping up and these are way cheaper elsewhere and they no quibble match them. It is worth it as RS provide great service in my ... MoreJust bought them with a Mojo 2, these are fantastic. They won't be run in yet, so expecting them to get even better over the coming weeks.

The Best Headphones - Period!

I just bought these because of bluetooth fatigue, and wanting more portable audiophile options.The sound? Breathtaking. Accurate. Well-balanced. And comfortable...like wearing nothing at all in your ears.Listen to jazz and classical on the road. You can feel and hear the fingers on a stand-up bass, the vocals with expression previously unheard of with headphones of any size for this listener.The soundstage, separation of instruments and voices, the clarity, the crispness.These headphones are a true marvel. These are on a par with closed headphones which are also transcendent, like my $1800 Sony Z1R's. But those are big and not portable.With the IE600 you can travel light, and listen big!For years my go-to headphones were the Sennheiser HD650's.

Makes sense that the same company is now making the best portable solution for blissful listening.Beyond my expectations. Highly recommended.

Unbelievable Detail in Sound

After listening to these IE600's, I am not really sure I can go back. I did not even realize what I was missing until I had put these on and then reverted back to the IE300's. The sound is just ever so slightly finer, more granular, and by all accounts better than any of the cans or IEM's that have been through my ownership. As silly as it may sound, I almost want to say that all music is somehow more musical through the IE600's, and that's without any personal equalizing.Everything is detailed. The bass is clear. The mid is clear. The treble is clear. The resolution within these drivers is incredible. These could give you new appreciation for the music in your collection, even if you have listened to them for years as you added new favorites to the list.Despite ... MoreAfter listening to these IE600's, I am not really sure I can go back.

You really are getting a great value product considering how much more you would have to spend to get the same quality sound through other means, whether it be headphones or IEMs. There is no competition, and I easily recommend this to any and all!
