I have my Reecho SG-03 now and have gotten to listen to them for a handful of days on & off now! Let's go!
All in all really good stuff for $69 if the signature suits your tastes & listening preferences. They have a W-type profile/sound signature as others have stated before. The included case is a nice little welcome & I like their brand printed on it, even if it is a little too small & made with a scratchy material. The shells & fit are very nice with solid isolation. I didn't like the thin stock cable that was kinda tangle prone & had stiffened coating wire ear guides. And the tips provided were fairly minimal, which is fine by me cause I prefer other tips almost always. I was using the SG-03 with JVC Spiral Dots(OG) but they are a bit too bright/more metallic up top that way with such a short+wide bore tip that brings out more upper mids/treble presence. I bought some FAudio white "Instrument" premium tips(learned about from the Tweaking Tips post on audioreviews.org). They aren't as soft, squishy, or comfy as the Spiral Dots, but they pair extremely well with the SG-03 sound wise imo. So I recommend them. I got them here from MTMTAudio:
https://www.mtmtaudio.com/products/...-silicon-3-pairs-white?variant=32465676075068 They are a regular/medium length bore and a medium bore in width.
The upper mids/lower treble on these are just a bit strong for my ears without a good tip match. And the lower mids are a tiny bit too scooped. Sub-bass focused low-end is superb, mid-bass & upper bass are pretty good, and upper-treble is pretty great as well! Oh, and mid-mids are good in clarity, if not a little thin. The tonality is a bit colder at times for mids & upward, a crisp set of IEMs. But the meaty bass range brings some warmth & rumble too. Timbre isn't super natural sounding for a dynamic driver, when compared to something like Zero Audio or Sony's more organic timbre imo. It's almost a little bit sharper like a BA kinda? I much prefer DD's in general. Details/resolution seem really good for the price. Micro details are there/present quite a bit too. Soundstage is moderately good for an IEM at sub 100 USD, wider than tall or deep but not the widest I've heard(Also, am used to my $300 Sony MDR-MA900 headphone's soundstage tho). Separation & layering are really nice for the price, more capable than the soundstage I think. Pretty fast/quick sound overall with great technicalities at the price. I think these are a great value for under $100, let alone $69, and maybe even a decent value for under $150. I really love them overall
I have been driving them just with my LG G7 ThinQ & its built-in Quad DAC. I use it fairly loud to me around 30-37/75 volume. I also like them very slightly EQ'd in Poweramp Music Player for Android. I added 1 bump or 1.5db at 500hz & 1khz. Then -1.5db at 2khz, 4khz, & 8khz. These slight tweaks smooth them out just a hair and make them a little more balanced/tolerable/less fatiguing tonally for me for longer listening sessions while not ruining their signature or any technicalities they have. The IEMs have a sensitivity of 106 db @ 16 Ohms, so it's easy to drive thankfully too! And their listed requency response range is 20Hz- 40kHz.
I listen mainly to a wide variety of EDM songs I have found over the years. But I also like Alternative, Rock, Classical, Folk, Lofi, Video Game OSTs. Pretty much anything except Country, and I guess not really Jazz. These have a good crunch/bite for EDM that is enveloping & great quality sub-bass that has authority when it's there in the original mix. They are good for Alternative, Rock, Classical, and OSTs as well as far as I could tell. I don't know if they'd be good for Metal or fast music with super complex sections or not though. Might need something more technical/even higher-end for that & to reproduce it very well.
I am using this YY 16-Core Upgraded Silver-Plated Copper Cable, which is nice

I ordered it for $29 from HiFiGo, which was supposed to be this:
But they sent me that other colored one pictured in the Ali link not anywhere on their site :/ And they couldn't fix their error cause they didn't have/guarantee the color from the manufacturer that was pictured I ordered... So they offered me a coupon for next order. And am just using the cable that works fine/great, but not fully what I wanted looks wise.
This has been my 1st new set of IEMs since I bought the iBasso IT01(~$80-100) back in Sept. 2018. I also still own a pair of Zero Audio Carbo Tenore(~$35-55) and Zero Audio DuoZA(~$90-110) back from 2013-2015. And these are just as good if not better? than those IEMs. These even hold their own against the Yamaha EPH-100 I think. And even surpass the Havi B3 Pro 1(I hate their fit & signature) & JVC HA-FXD80(too scooped, cold, and bright & painfully large nozzle imo). I like this signature better than any of those 3. Plus the SG-03 are more comfortable for a longer period of time to wear than the IT01(with a better housing & nozzle), even with less comfy tips on them. And no driver flex comparatively. I have squishy, white wide bore TTPOD T1E tips on the iBasso IT01. They are the comfiest, best sealing wide bore tips ever imo even if the IT01 housing is a little bothersome after a while. They're slightly better than the Spiral Dots to me. However, they don't fit the nozzle or synergize well with the Reecho SG-03 like the FAudio white "Instrument" premium tips do.
Well, hope this was a fun & somewhat informative read
And as always, stay classy Head-Fi
