Also the Astrotec S80 Plus True Wireless Earbuds even sound BETTER when using "ALXCD Replacement Foam Eartips for Galaxy Buds Headphone, S/M/L 3 Pairs Soft Foam Earbud Tips". They never feel like they are going to slip off my ear. Please advise? Might work for someone else, but I ordered small and they were still too large. You can trim them to fit, but if you have slim toes, small toes, these may not fit well. Esta función en los H9i funciona perfectamente, al ser circumaural el sensor lo tiene más fácil para detectar la oreja, pero en los H8i no funciona tan bien. You get a nice cable compartment which also can be moved. The software does allow per key lighting, and it has some really pretty effects. And the price of these far exceeds what one might expect for the quality and workmanship. Only had it - the new version with the 12 ft cable - for 2 days, but so far so good.
