SennheiserIE 600 in-Ear Audiophile Headphones - TrueResponse Transducers for exquisitely Neutral Sound, Detachable Cable with Flexible Ear Hooks, Includes Balanced Cable, 2-Year Warranty

After all the hype about these headphones that I saw in YouTube reviews, I decided to give them a try since I consider music as a fundamental part of my life and my state of mind. I've been using them for a few weeks and I can say that they are my favorites. They have the perfect tuning to my taste, the music just sounds alive, it gives emotion and pleasure to listen through them. It's true that the treble can be a bit loud, but it never gets to the point of tiring or sibilance, I find it gives the music life and air. They are comfortable to wear for long hours and immerse yourself in your favorite songs.Cons: the ear tips that comes with the package do not work, they are really bad. They make these earphones sound flat and lifeless. I replaced them with some type e eartips and the difference is overwhelming. It bothers me that such an expensive product makes me spend extra money to make them sound like they should. Another point against it, I would like the cable to have a microphone and thus expand the range of use.In conclusion, I totally recommend them.*To the Sennheiser team, they must create new ear tips that really work.

About the headphones themselves: they are some of the best you can buy. Sound quality is top-tier, comfort is probably the best I've tried. Incredible package and truly and endgame IEM. The eartips are mediocre and the cables are alright at best. It does come with a nice hardcase and 4.4mm balanced cable which is nice I guess but the overall cable quality is lacking. Highly recommend the Null Audio custom cables if you want to upgrade.Now to everything bad: These lasted about 2 weeks for me. At first I was convinced something was going wrong with the fit, the left IEM sounded like something was covering the opening. I could manipulate it and it would come back to life and then die out again. Tried different cables, ear tips, everything. I went to check online and this apparently is quite common! This truly floored me, I've owned probably 20+ IEM's and headphones, most made in China and cost less than half of what these did and I've yet to have ANY fail. This are made in Germany and are well above average in cost, arguably way too expensive in a world where Moondrop makes IEMs (see Blessing 2:Dusk, Variations).So I reached out to Sennheiser who quickly sent me an automated RMA packet with basically no instructions. I had to pay for shipping to get these sent out, but I didn't want to take the chance of returning only to get another bad set of IEMs. Reading online other people had just shipped back the bare headphones and had them quickly replaced. So I did the exact same, which cost me about $10 to ship to their QC department. Much to my excitement I received a package back from Sennheiser in about 5 days only to find they didn't even bother to open the package containing the IEM's and sent me a notice that I would have to send the ENTIRE original package back to complete this process.I quickly sent off an email to them explaining the situation, here I had PAID to return brand-new defective headphones which they rejected for repair based on not having the original box and presumably.....ear tips? Well it took about 5 days for them to respond and it was essentially an automated reply stating I would need to re-ship the headphones to them again with no further explanation.Screw that. Immediately shipped them back to the seller for a refund. World Wide Stereo was fantastic in paying for the return shipping and good instructions on how to do this. I'll consider buying these again in the future when I'm feeling brave but honestly what a garbage experience for a supposed 'high-end' product.In short, I would NOT buy these open box ever. My bet is they are defective returns. I will likely only consider getting them from authorized dealers with good return policies as well. If you get a good set you will be quite happy but good luck if you don't!

These earphones sound very nice. Full bass, nice midrange and detailed treble. Instrumental timbres are reproduced to my liking. Vocals are natural and clearly defined. Overall well-balanced, musical and good soundstage. The IE600's are well-made and extremely comfortable to wear.The high tech, 3D printed material is light weight and a perfect fit for my ears.The cable works fine, although there is a tendency to tangle sometimes. I use the 4.4mm terminated one in my music player. The included silicone tips (medium) work for me. They provide fairly good isolation, especially in 'normal' environments. (In a room with a TV playing, I do hear it slightly between music tracks.) The included cables and other accessories are of good design and quality. The semi-hard case works well. Overall packaging is good - everything displayed clearly and most importantly: protected. The printed manual has useful information for owners. I am very happy with the IE600 earphones from Sennheiser and am enjoying them very much. I purchased them from Buy Top Tech store on Amazon - an authorized dealer.

These are some top rated IEM’s, and for good reason. If spending over $100 for a set of headphones is too much for you, then you can stop reading right now and look at the IEM‘s from Linsoul or KZ. As most all of the reviews online have said, they sound very good, the only caveat is if you don’t like a lot of treble , you will need to EQ them down a small amount. They are very small, light and well built. It has a 7 mm dynamic driver and so it has that slight pop to the bass that you don’t get from the balanced armatures. I have an eclectic selection of in ears, several KZ’s and 5 pairs of different Campfire audio as well. Campfires are American made and are beautiful both to look at and for sound quality. But they are far more expensive and I prefer the IE 600s over everything else in my collection. Besides the previously mentioned spicy treble, the stock wires are a major disappointment. And it’s very hard to replace those wires because of the proprietary MMCX connector. I have replaced the stock cable with Effect Audio Cadmus, which has improved the sound quality and drapes over my ear better, which helps keep them in place longer. Because they are small, the stock wires can put tension on them and pull them out of the ear, which was a little frustrating. They are easily worth the $500 that they’re asking for them now, $799 is a bit much. This of course, is a personal opinion, as they always say your mileage may vary, but being Amazon, you can return them if you find the sound profile doesn’t match your headspace. Happy listening.
