Linsoul KZ ZS10 Pro, 4BA+1DD 5 Driver in Ear Monitor, HiFi Wired Earbuds, Gaming Earbuds, Hybrid IEM Earphones with Stainless Steel Faceplate, Detachable Cable for Musician(Without Mic, Dark Black)

Short version – the KZ ZS10 Pros provide great listening with rich bass, embracing vocals and notable highs. Using the iFi Audio Hip-Dac and Apple Music I choose these over my Shure SE-535s, the HD660S and Sundara, KZ-AS12 and Sony MDR-1AM2. Most of the time. The provided cable is a bit short and tends to tangle. I’ll replace it when it becomes more important than just listening.Not an audiophile, or any kind of expert or specialist when it comes to headphones or to music. I like particular music genres more than others and am really not a heavy listener. When lossless came out on Apple Music it was the metrics of what was being offered that drew my attention. What possible difference could Hi-Resolution Lossless using 24 bit at 192 kHz make? Why would I even care?I mainly listen while biking, running, flying or exercising and am more concerned with not shorting out my earbuds with sweat or dropping them onto the street when the wind really blasts. If you’re on the move the value of lossless will be apparent, but it’s not that critical to extract everything you can from the lossless encoding and the headphone specs.The jump from the CD-ripped music at 320kbps and iTunes 256kbps songs that make up my library to Apple Music and lossless has been dramatic. (My entire stored library is now archived to a backup drive and everything in all my playlists comes from Apple Music’s lossless cloud of songs). Even without what I can now hear with lossless, the massive music library provided by Apple Music is worth the subscription. With lossless, the music is transformed.These relatively inexpensive KX ZS10 Pros are outstanding for me. I only bought them at under $50 to try out because of their great Frequency Response spec and the solid Amazon reviews. They have become my go-to headphones, and the baseline I use to compare with anything else.The frequency response from the specs is stated as 7Hz-40kHz. Regardless of any analysis about human ears being stuck in the range of 20Hz to 20kHz I enjoy the sound of those with wider range, and by a lot. I find that the bass seems more deep and rich, the highs more detailed and realistic. So, the range on these is excellent.Others in my listening adventures include the KZ-AS12, Sennheiser HD660S, HiFiMan Sundara, Shure SE-535, and Sony MDR-1AM2. Also a bunch of other much less expensive earbuds and headphones, but comparison isn’t really useful with this collection. I’ll also watch Joshua Valour, ABYSS Headphones, DMS and Darko Audio on YouTube and check out the breadth of opinions about headphones on Reddit. Mainly to learn more and to figure out what I may be missing. And continue the quest for a next level listening experience. (Have not approached an Abyss Diana or one of the Audeze LCDs. …yet).I personally find that IEMs, earbuds, are my favorite way to listen to music. So far none of the over-ear headphones has dissuaded me of this view. These KX ZS10 Pros have a really nice fit for me. Using memory foam earbud tips these seat and seal nicely and I’m barely aware that I’m wearing them. And I can easily wear them for hours. All of the over-ear headphones mentioned are comfortable, but they all do tend to become less comfortable over time, mainly due to heat.To net out my experience, these KZ ZS10 Pros blow away the Shure SE-535 (my up to now favorites, and my long-time traveling companions) and the KZ-AS12s. Better and richer bass, more lively engagement with the music. The HD660S and Sundara are both excellent, but I did not find them enough different from the KZ ZS10 Pros to warrant spending so much more or dealing with my own comfort preference for IEMs. The Sony MDR-1AM2 has a frequency response of 3HZ to 100,000kHz, which I do notice. They do not have quite the same overall quality of sound as I found with the HD660S and the Sundara, but the Sony’s are clean and consistent. Most of my listening uses Apple Music on my iMac and I use the Acoustic preset in the Equalizer to deepen the bass and accentuate the vocals. The MDR-1AM2 with the balanced cable also offers me a great listening experience, just a bit less in comfort than the in-ear KZ ZS10 Pro.Exploiting lossless tracks requires more than the built-in DAC on my iPhone or iMac. My choice was the iFi Audio Hip-Dac Portable USB DAC and Headphone Amplifier. It has the power to drive all of the headphones and IEMs I’ve tried, has a “bass boost”, excellent volume control, and includes a balanced 4.4mm headphone jack (which is great for the MDR-1AM2s). Also, battery powered for mobile use although it pretty much spends its whole life connected to the iMac. For me, so far, this little DAC/AMP is outstanding. (Although I keep looking at adding more options and more power … but I keep reminding myself that I really don’t listen all that much).As I said, my listening is somewhat limited. The songs that have really accentuated what lossless can provide and how these KZ ZS10 Pros perform include Eyes of the World and Bleed to Love Her by Fleetwood Mac (two of their songs I had never listened to until engaging with lossless on Apple Music and exploring these headphones), Enough of the Night by Jackson Browne, Knee Deep by Zac Brown Band with Jimmy Buffett, Keith Don’t Go by Nils Lofgren (who I don’t really listen to, but the acoustic opening for this song puts the guitar inside my head), and 4ware by deadmau5 (added to my list because of a lossless headphone review site that tests using it …). Elvis With The Royal Philharmonic Orchestra offers an entirely different level of appreciation for Elvis with this remix album, in lossless. Lossless Lionel Richie (Sail On, Ballerina Girl, Stuck on You …) offer both delicate guitar and rich vocals. The Killers, The Weeknd, Uncle Kracker and sometimes Mat Kearney become over saturated using the Equalizer settings, but lossless versus 256kbps offers a significant difference in listening experience.

In an emergency I ordered these to temporarily replace my higher-end IEMs, and boy was I pleasantly surprised! Great sound quality and clarity for the price, and they've seen me through a couple weeks of gigging with no major issues. Even for my small ears these are comfortable enough to wear for a 4-hour set. My one complaint is the ambient static you'll hear, but that's easily lost in the mix when the full and is playing. 10/10, my new fave budget IEMs! (Easily better than 125s.)

Tl/dr: good for the price, but a bit stinky.I’ll preface this with saying that I do not consider myself an audiophile. I’m not someone that seeks out FLAC files, HAS to stream 320kbps, or gets into the details of drivers. However, I am nearly constantly listening to something, whether it be music, podcasts, audio books, etc. I listen to a wide range of music from EDM to classic country to Metal Core, Hardcore, rap, so on. I consistently exceed the 100k annual minutes listened marker on Spotify.In an effort to escape the allure of doom scrolling and constant connectivity (read: distraction), I’ve recently purchased an iPod Touch to have with me while I work. I have a set of Jaybird Vista 2’s and a set of Sony WH-1000XM4 headphones that I enjoy listening to, but wanted a corded solution that wasn’t the little, white, trash-sounding ear pills that Apple sends with their devices.I am satisfied with the initial sound, fit, quality of these earbuds. They’re lighter in-ear than I expected and wear fairly comfortably. The bass isn’t as intense as I prefer, however they definitely do not sound tinny. Very clear sound that projects well (imagine the origin seeming to come from the center of your head). The cord length is long enough to keep my iPod in my back pocket while working, or nearby, but not so long that it gets in the way.Speaking of the cord… it’s stinky. There is a bit of off-gassing from the product when you open it. I’m a bit sensitive to scent, and I can smell the cord while I’m wearing the headphones. It’s slightly noxious but I assume it will dissipate. This is why I rated four stars instead of five. Also, superficially, I would’ve preferred a black cord, but it’s not a dealbreaker whatsoever.Thus far, I am satisfied with this purchase and would recommend for those looking for a better-than-baseline earbud.
