Rarely write reviews , but would like to recommend Bludio headsets , all kinds . I have used maybe 10 of these sets over the last few years and never dissapointed with themI mostly use for running , after trying various in ear kind /ear buds which never seemed to work for meThey are conveniently micro usb/usb c charger and charge seems to last forever, atleast more than 2 hour continuous usage(never ran out of charge even in my longest runs)Dont know how do they make headsets at these price points. I used then in snow, thunderstorms, extreme heat with no problems. Rain and sweat also did not cause any problemsFor the first time my recently purchased t5 active noise cancelling headset was not functioning . Was not able to switch on despite multiple attempts at charging. I was travelling overseas and explained the problem to there customer service , got an immediate response, they sent me a free replacement which is working the usual excellent Bludio way and did not even need to ship the non functional headset backOverall great experience with the company, performance, ruggedness, great sound volume and clarity and most importanly responsive and fast customer service who work with you do more than obligated and go the extra mile to make customers happy.
