Linsoul SIMGOT EW300 1DD+1Planar+1PZT Hybrid Driver in Ear Monitor, Wired Earbuds IEM, Gaming Earbuds with Detachable Nozzles, Silver-Plated OFC IEM Cable for Audiophile Musician (EW300 HBB)

Arrived overnight in a secure box enclosing the fancy looking IEM box. Very nice. The cables snugly attached onto the IEM shells. Nice labeling to indicate LEFT and RIGHT. Came with 3 sizes of ear tips and installed the medium size giving a great fit as if the IEMs were not not in my ears. Well done. Tried the gold nozzle but it reduced bass and treble. Preferred the silver ones which are straight thru while the gold ones have a plastic deflectors around the IEM exit canals. Using a DAC/AMP with 2 watts per side fitted with AKM 4499+4199 chips. The IEMs are quite efficient and did not push them too much but did at first. The BOTTOM HALF covering the bass is very powerful, articulate with good definition. Terje Isungset's In Memory of Nature Pt. 2 has a bass reproduction that can rattle you brain. Porcupine Tree, Dayshell, Of Mice and Men metal offerings come out very full and bombastic sounding. Phronesis, GoGo Penguins are clean and powerful and clean. Acoustic bass from Nenad Vasilic and Terje Gewelt are powerful and clean with great articulation. The UPPER HALF is where it can get tricky. If pushed to hard, the treble can get tizzy and chaotic lacking instrument separation especially when it is crowded with too many high pitched instruments. Like in Nika Niles' Synergy, it is very hard to differentiate the high hat, crash, ride, and splash cymbals...they all pretty much sound the same and indistinct - just one TISSHHHSSSHH. This very likely due to the design using Piezoelectric drivers that gives the tizziness in the upper registers especially with cymbals and not-so-good recordings. I do not know if this weakness in the sound reproduction will settle down after 100 hours of playing. This IEM seems to work well with pretty much any music genre including classical and female vocals. I think this IEM is fairly priced for the musical listening pleasure it will give you.AFTER 50 HOURS BURN IN: The upper registers in the treble region settled down and it is now amazingly clear and coherent from top to bottom with very little tizziness at the top. This is an amazingly dynamic and musical IEM. Kudos to the Simgot engineers for producing this gem.

I wanted to give these a few days before reviewing. I'm not an “audiofile,” and most of my gear is pretty low budget “mid-fi.” I used to buy IEMs before the chi-fi revolution.Choosing a pair of $80 IEMs was no easy task given the ridiculous number of affordable models now available. It’s a different world from the 2010s, when my Fiio EX1s were considered to rule the budget IEM space over on head-fi.My primary criteria were soundstage, “fairly” flat tuning (anything less than a V), clarity and separation, and tight bass that wouldn't bleed into the mids. I narrowed things down to the EW300s, Hexas and Aria 2s. Although it would probably appeal to actual audiophiles, on paper, the upper mids of the Hexas seemed more accurate and neutral than I’d like for EDM, and I wasn't sure how much tweaking I could do to the bass. The Arias supposedly have a killer 3D-ish soundstage, but QC complaints scared me away. Look around, and you won’t find a lot of negative reviews of the Simgots, so I felt you really couldn't go wrong with them. There's a cool Youtube channel “Glenn Gane Audio” that features audio simulations of iems back-to-back. Very helpful channel.I have eclectic taste, but this purchase was primarily for EDM. Since iOS has no global EQ, I picked up a Qudelix 5k (HIGHLY recommended). The EW300s arrived—they look and feel high quality. Nice accessories. The cable is perfect. These iems are incredibly comfortable and stay put in my ears.As with other headphones/iems, volume output is poor on iOS products. I picked up a Qudelix 5k USB->iPad Pro and the Simgots came alive. They perform much better with extra power, and do well with EQ. I wasn't sure how well the planar would handle heavy EDM bass, but it does it well.Separation and clarity seem good. I've found that the 4k 11.3k region can get a bit hot, which could potentially be fatiguing, so sometimes I'll reduce these frequencies slightly. The bass is full, warm, and relatively punchy. At the moment, I’m using the gold nozzles with foam inserts that are part of the accessories kit. Wanted to see if it could take some of the bite out of the treble. I might prefer the silver nozzles sans inserts. Still A/B-ing them.The silicon tips are great and stay put. Although the nozzles don't seem that long, I can get a good seal. These are my favorite iems yet. Versatile all-rounders with a pretty refined smoothness. And that cable.... beautiful. Zero regrets, and an easy 5-stars.
