I bought the Jaybird brand because my husband likes his. I opted for complete wireless and he just has the Bluetooth ones with the cord connecting the two buds. These are cool little buds, good for working out without the bulk and the wires. They come with a few different tips to swap out. I have small ears so it took me a few tries to get the right combination. Now that I found it, these are perfect for running and they even stayed in during my boxing workout! I haven’t used them on a phone call yet so I can’t say how well they work with the phone. Musically these do the job. I just wish they could go a little bit louder that’s why I only gave 4 stars. Comes with a charging case that charges and stores them.

Bottom line, I returned them. Pros– great sound, almost too portable, rechargeable case, jaybirds app is awesome to customize sound, water resistant and never fell out.. Cons– large headphones in the ears which maybe uncomfortable after more than an hour, while watching videos the sound wasn’t in sync with the video, battery life is so so at best, my charging case died within 2–3 weeks, and no comply foam tips. I think these headphones are great for the person who runs 5ks to half marathons and wants a great looking and great sounding headphone. If you train a lot like myself, you may need more battery life like the X3’s 8 hour battery life. I’m huge fan of jaybirds since the X1’s and owned 2 pairs of them. Cordless headphones are new so there’s bugs to be worked out as in all new products. On that note I can’t wait for the run 2.0’s.

These are the best as far a comfort for working out. You hardly realize you've got them in your ears, and very light weight. I just wish you could pump the volume a little higher. But other than that, their awesome!

The fit is very good the design is very ergonomic , but the bluetooth connection is Very bad, cut out the connection very often and the left earbud has low volumw than the right ear bud. I am a fan of jaybird since x buds to x3 and now the jaybird run made me so disappointed.

I really love the Jay Birds for jogging that my wife had me buy her one also. Definitely easy to set-up to ur phone, very comfortable to wear and the download app definitely gives u that maximum sound.
