I bought these because I had lost one of the earbuds to my Sesh evos at work and it would cost me roughly the same to buy these refurbished as it would to get a replacement bud for the Sesh Evos. The battery life is much better, normally using one ear bud would last me about 4-5 hours, with these I can last closer to 7-8 hours. The sound quality is quite good, I use these mostly for audiobooks and podcasts but when I put on music the sound is as clean and deep as when I wear overear headphones. Range is so-so, on the Sesh Evo's the BT could go about 200ft before I started getting lag or dropping signal, on the Grind Fuel it's under 100ft as they start to drop when I go into my garage with my phone left in the room, not a big problem as I can just keep the phone with me.
I can't tell that these are refurbished, they came in original packaging with all the accessories. There is no visible wear on the earbuds or case, I've had no connectivity or battery issues that you normally get on a refurb, they were essentially brand new for a small fraction of the original price. I will not hesitate to buy these again if I lose another ear bud.
