“ Overall shallow V signature. Bleed- and boom-free bass that's punchy and fairly detailed (not much sub-bass) - just right for me. Mids are a little dry but good detail and vocals are very listenable without being too forward. Highs are crisp and detailed - was bordering on sibilant when new but has developed control from around 25 hours onwards - but would like a tiny bit more sparkle for my...” --wysinawyg
“ Imagine the GR07 with a better refined and slightly more prominent treble, with the bass quantity, weight, and rumble toned down slightly. With that said, I suggest bassheads to look away (why would you be looking at a TWFK in the first place?). The bass is well controlled and will show up when called for, though obviously not enough to satisfy a basshead, but is adequate for me...” --Reomero
“Build quality: 4.5/5 Thin wire, but further more everything looks tight. Sound quality: 4/5 It’s personal but this is my opinion: this IEM comes short on all fronts except bass and soundstage, from which the last is an obvious result of the use of ventilation holes in the back of the housings. The bass might even be overpresent for some (it is the Bass edition though), but the key fact for me...” --BlastAway
“I prefer the GR04 to my Visang GR02 and greatly prefer them to my Soundmagic PL50 (I don't like the PL50). This review is not going to get technical. The main purpose is to share my EQ settings which makes them sound more like my HD600 which is my reference headphone. In short: Great SQ for the money if you take 30minutes to EQ them. EQ settings: (from PlayerPro on Android OS). 0db...” --Rune3400
“ Hidden amidst an array of confusing sister models, the Vsonic GR04 Pro Flagship Edition is one of the best values in IEM's. The Pro Flagship is second only to the much acclaimed GR07 in the Vsonic lineup; however at about half the price proves a far better value. Coupling intuitive pivoting tips with a reasonable balanced sound signature, the Pro Flagship deserves far...” --thecansmancan
“ This is my first ever review so bare with me. My background in iem and headphones in general is limited. Reference iem that I own and judged against the gr06 were jvc air cushion, klipsch image s2, meelec m16 and entry level sennheisers. Soundwise they just blew away every iem I had heard until now, everything sounds better got great bass, mids and highs. ...” --executioner
“ 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
