Use this when riding my motorcycle. Sound great and no connection issues. Battery life is superb. I like that I can use different Ear buds with it as well
solid connection doesn't have the skip song function built in and the double pins bend really easily so be careful about that. Its easy to bend them back straight but it still makes my heart drop everytime it happens. Also the battery indicator on my phone at least isn't the most accurate so make sure to be on top of charging them otherwise without warning they will just shut off. But they can definitely power my imr aten 2 very and they sound great. ALSO MAKE SURE U HAVE DROP EARBUDS FOR THIS, the pins are surrounded by this large square compatible only with drop earbuds so i have to file down the edges of myn to make it fit.
Work fine for my tinfis. I haven't worked the battery super life super hard, but on my box I think it says 4 or 5 hours, which seems about right. You can pretty consistantly get these on amazon for about 7 bucks more then the drop price I paid, if you want them right away.
