“The HY3 is a three-way, three-driver hybrid custom in-ear monitor from Sweden-based Cosmic Ears. It utilizes a dynamic driver for the bass and twin balanced armature drivers for the midrange and treble, which used to be a very rare configuration, although hybrids have increased in popularity over the past year. The bass unit looks to be around 8mm in diameter and has its own sound bore. The two...” --blueangel2323
The HY2 combines a dynamic driver for lows and a balanced armature for the mids and highs. This dynamic driver also delivers an increased soundstage. The HY2 is a great sounding monitor for those looking for something a little different by combing the 2 driver technologies. Twin hybrid – 1 for lows, 1 for mids and highs Full sized medical grade hard acrylic shell Various...
“ Summary: These require deep insertion. Once inserted they are neutral, extended and adaptable. They don't really have any sound signature that shines through recordings but instead adapts to what is being played. Great for the price. Very versatile. I bought these used from a fellow head-fier. Coming straight from the GR07, they sounded bright, dry, flat, grainy and...” --MoonYeol

“Copied from: http://www.head-fi.org/t/686039/cosmic-ears-ba4f-review I'm finding it hard to rate these, for the price I would give them 5 stars on every department. But I'd rather rate them, referenced with the idea of what the very best cIEM could be. The BA4f with the Ice Blue color Short History Before I started my journey into the cIEM...” --Marleybob217
“I've spent the past week auditioning these new VSD1S by VSonic. Before this I was listening extensively to my dual dynamics JVC FXT90's and my dual armature UE 700. For a single dynamic driver that is priced below $50.00, you get something tuned to compete with above $100.00 IEM's. Within a few hours, I realized that my VSD1S sounded as accurate and sonically equal to my dual FXT90! Though the...” --IEMagnet01
“ The VSD1 is the latest in a rather long line of budget in ear monitors including the VC02, GR99, GR02 and others that promises high quality sound for around $50 or so. While I haven’t had the opportunity to hear any of VSONIC’s other budget offerings, I was quite impressed with the GR07 Bass Edition I purchased and reviewed some time ago. When the opportunity to review the VSD1...” --TheGame21x
“ I received my GR07 MK2 a few weeks back, and they have gone through the hundreds of hours supposedly required for burning in their bio-cellulase drivers. Having gotten over my new toy effect, I still enjoy them immensely, so I figured it’s time for my first review. This is modeled after the reviews of legends like |Joker| and Swimsonny. I hope this helps you as much as they have...” --tzjin
“ Introduction VSONIC is a well-known name in audiophile circles, with rave reviews coming from their GR07 monitors, which have recently seen an upgraded Mark II version and, the version I’ll be covering today, the Bass Edition. As a natural basshead, I was intrigued when I...” --TheGame21x
“ VSonic GR07 is a great example of IEM strong because it has few flaws and almost all of these are possible to correct with a good equalizer. Bass is perfectly controlled, excellent texture, very well extended (-6 dB at 30 Hz with perfect seal), perhaps a bit warm due to high-bass boost (~250 Hz). No bass bleed is present. Mids can be slightly forward to slightly laid back depending on...” --AstralStorm
