MaGaosi M1 Black Corded Dual-driver Hybrid Balanced Armature and Dynamic Metal Housing IEMs Earphone with Microphone

I prefer a flat frequency response and these seem to be pretty close.My two favorite full size headphones are the Ultrasone HFI 680 and Fostex T50RP. My favorite IEM are the HIfiman RE-00, KZ ZST and now the HLSX-808.The implementation of the Dynamic and Balanced Armature drivers has been done pretty well. The BA driver is able to respond very quickly, producing sound with great clarity and separation. The dynamic driver moves a significant amount of air resulting in hefty bass. The beauty is in the balance, the bass is not too boomy and the highs aren't too bright and harsh. My only complain would be that the mids are slightly recessed. There is a very slight bass enhancement, but it does not bleed into the rest of the spectrum and provides an appealing warmness to the sound. I also own the Nuforce NE 600x and KZ ATE earphones, they both suffer from a too large bass boost that bleeds into the mids and muddies the sound.Probably owing to the detailed music reproduction of the hybrid driver system, the soundstage is larger than typical.It comes with large nozzle silicon tips, which I did not like. I also tried Spinfit tips, foam tips, and spiral dot tips. I prefer the sound with the spiral dots.The HLSX-808 has become one of my favorite IEMs and I would recommend them to anyone interested in a balanced sound.

Sounds very good! unfortunately, it is too fragile.. the cable snapped when I got up and my phone was next to me! Not worth the money! I

For the price I don't think they can be beat.

The HLSX 808 is perhaps the best value you will find in an earphone. They meet or beat units costing many times the price. These are a steal at the asking price, far exceeding the Monster Turbine Gold Pro's which retail for around $300.Overall sound signature is not quite neutral having slightly elevated bass and highs. The HLSX is quite spacious, crisp and very detailed. Mids are ever so slightly recessed in comparison, but still fairly neutral. The HLSX 808 is a dual driver configuration with one Dynamic Driver and one Balanced Armature. This gives you the best of both worlds.Build quality is top notch made of all metal. You could probably run these things over with a car and not do any damage. Cable is of good quality. Very soft and subtle, not prone to kinking or tangles. It is possibly Kevlar reinforced, but I cannot confirm that. The 3.5 mm jack is straight with good strain relief. There is also good strain relief on the earbuds themselves. Comes with a carrying case and several tips.Bass hits low and smooth, producing some of the best bass I have heard from a dual hybrid. Very realistic, and lush, although it can be a just a tad wooly at times. The low end never overpowers, but does boom when needed. "Ninja" bass would describe that best. No bass bleed into the mid-range.Mid range is quite good. Vocals are reproduced well with good life like quality. Guitars have never sounded better on any other earphone under $500 that I have tried.Treble is the absolute best I have heard from a dual hybrid showing the power of it's Balanced Armature speaker. I just can't get enough of it. Breathtaking would be a good term to describe the high end. Never any simblance.Soundstage is well above average. Pretty wide, spacious, with magnificent instrument separation and placement.The HLSX 808 can be "tuned" using two methods. Try different tips. I don't know if you can get them anymore, but the soft tips from the Denon AH-C300 seemed best to me. Some on head-fi seem to like the Comply foams, but I found them to reduce the bass. On the inside of the earphone, by the nozzle, is a small port. You can cover this with a piece of tape or use some sort of gel glue. This will tighten the bass just a tad and lift the mids, if you like that sound signature. I would not recommend covering the outer port, but if you do it may be best to leave at least a pin hole open to avoid driver flex.The HLSX 808 is a Bang For your Buck Champion. As I said before, they destroy the Monster Turbine Gold Pro's which retail for around $300. Those earphones are now retired from my collection since the introduction of the 808. I have tried the Shozy Zero https://www.amazon.com/SHOZY-Zero-HIFI-In-ear-Earphone/dp/B01EHT6Z6C, which is supposed to be a "$500 IEM KILLER" and the HLSX 808 smokes them. Shozy's sound anemic in comparison. The HLSX 808 is also a notch up from the infamous Vsonic GR07 - $128. https://www.amazon.com/VSONIC-gr07-bass-GR07-Edition/dp/B00KM4N83K/GR07 The GR07 may be a little more neutral, but the HLSX 808 is much more lively, more detailed, and more fun. While I still do listen to my beloved GR07, I find myself reaching for the HLSX 808 9 times out of 10.Overall, for the asking price you will probably not find a better earphone. Resolution details, and even micro details are what you expect from something costing into the several hundreds of dollars. Check out the Chinese thread on Head-fi. The HLSX 808, for it's price point, is the most recommended earphone by the experts there. These are not hype as they are tried and true by dozens of the members there
