I didnt have a reason to upgrade either but I wanted the new ones. I liked the new feature of them being tied behind my head rather than the cable behind my neck, either way its wireless and being behind me neither never got in the way.
The Freedoms were very good, I liked them though I didnt like how big they were. At the time it didnt bother me because again they were wireless. I had huge BT connecting issues. 95% of the use on the freedoms were at the gym and I usually left my phone either under the bench so the weights wont hit it. I could not get up and walk about 7-8ft without losing connection. Sketchy connection when Im sitting doing an exercise on the bench and the phone is under the bench (maybe 2ft away)? They sounded nice, call quality was not good though I never used it to call anyone. Only some phone calls I needed to answer while at the gym. I ran with them a handful of times and just holding the phone in my right hand caused skipping and bad connection. I felt I needed to keep it on my arm no matter what and didnt want an arm band. Good wireless headphones but bad connection on my pair.
I got the Bluebuds X the day they were available, I got the white ones. I LOVE LOVE LOVE these. BT connection is no issue, I havent had any problems connecting actually. I can walk a good distance away from my iP5 at the gym and still hear the music perfect. Audio is very good, and they still use the same wings as the freedoms did. You have 2 different options of wearing them under or over the ear. These headphones paired with Comply foam tips = best/comfy pair ever! No gym noise, nice tight feel. see the attached picture of the combo.
I actually got them for FREE!! I originally bought them for full price. They had a very simple, pretty much a steal facebook contest which theyve since changed their contest. When I got the bluebuds x in the mail, they came with a sticker. The sticker was a facebook contest on showing off the sticker, tag JayBird and myself on it and JayBird will pick a daily winner. I was the only one who posted something and won a free paid of JayBird headphones of my choice. I picked the white Bluebuds x! I returned my pair because I had just got them a few days prior. Got my money back and got a free pair of JayBirds! It was pretty much a steal! They still have daily winners on their website.
