So I've only got about 10 minutes of listening in... here's my impression so far. I immediately popped on the large sized JVC Spiral Dot tips. They seemed pretty big... I put them up into my ears and they took a bit of persuasion to get into place. At first, the music seemed... cloudy. I was not impressed. After a few minutes, I replaced the stock tips that came on the A83's and things seemed much better - my money seemed like it might be worth it afterall, as they sounded pretty good. I thought perhaps the Spiral Dots are too big and are wrinkling or something, causing a bad seal. I swapped one tip back to the Spiral Dot, and pulled each ear in/out, and listened to both together. The sound seemed the same. I need to experiment some more with the tips obviously. I can shove my pinkie finger into my ear canal (not all the way obviously), and the stock tips are way smaller than my finger. Maybe the Spiral Dots will work, maybe they won't... bass is okay, not very much oomf behind it, but it punches and is tight, at least for my EDM tracks. Highs are quite nice, but I caught a bit of a shrill from some sounds that was unpleasant. Maybe the Spiral Dots will prevent this, but as I said, need a lot more listening time and will compare with the Westone's when they get here. I plan on leaving them playing music on my computer for awhile to see if any "burn-in" helps. I played tracks on both my Note5 and PC sound card, and no real difference stood out. Maybe if I have time tomorrow I'll listen more, but certainly by this weekend I'll get some time in. I do have to say I am concerned about my hearing. I don't turn the music up even close to 100%, more like 60-70% on my cellphone (the point where I feel like I am hearing all the detail pleasantly), but I almost feel like it is too loud and might damage my hearing... any tips for this?
