Pros: listening to music with these headphones is awesome. The bass and clarity is phenomenal. The case and headphones both hold up well battery wise. Cons: You cannot use the left earbud without leaving the case open. For example, you use your right ear bud and the battery dies. You grab the left one while the right one charges. If you close the case connection is lost immediately. You have to leave the case open. This is ridiculous, because if you’re traveling, walking, etc., it’s very difficult to walk with an open case. Also, sometimes they connect quickly, sometimes you have to tap the ear bud and move your head around to get them to connect. Other times you have to place them back in the charger close the lid, reopen, and try again. On some occasions I’ve had to open/clase the case multiple times to get them to connect. Ridiculous. The shape of the headphones is a bit awkward and takes some getting used to for you to insert in your ear. The last major con is that making phone calls is horrible. The other person can’t hear you clearly at all.

Amazing sound with Amazing bass. Love the features of jumping through tracks with just a touch and how the music stops when you take out the right earbud and starts back automatically when you put it back in. I have not tried taking a call yet with them. The only negatives I can give is I wish there was an option to adjust the sound mix to adjust the treble and bass. Another option I would have loved to see is there be no noise canceling at all. These headsets do muffle the sound where as with the old wired sound sports, the sound was still awesome but you could still hear people talking to you. With these Bluetooth earbuds, it does muffle the sound. So if you are looking to use them in a work environment where you need to hear your co-workers speak to you, you may have to consider another option. Otherwise, Bose has always had an amazing product and have always been worth the buy in my opinion!

These are amazing headphones. The sound quality and fit are absolutely unmatched by any other. I have owned these and Bose's Quiet Comfort models, and the Sports are by far the best ones you could get. Its an absolute shame that these are no longer available. The only issue I have ever personally encountered with these earbuds was that one of the earbuds stopped connecting with the charging/syncing case overtime. However, both Bose's and Best Buy's customer and product support services have been top notch and Best Buy always replaced them with a brand new pair, completely hassle free. Hats off to Best Buy!

I got these to replace my old model Free sound sports. These are better in design and more comfortable for longer wear! The sound quality is excellent for this price point! I would definitely recommend these to anyone who stays active while listening to music.

These are descent headphones. They are truly wireless. Charging case is easy to use, a little slippery though so hang on to it or it will slip right out of your hands. You have to use the app to switch between the device you want to connect it to. This is one of the major negatives. It remains "connected" to one device until you select a different one, even if the other one is not in range. I am only using it with my new Hydrow for now, so I just leave them connected. But if you want to switch between phone, computer, tablet, exercise machine very often, this might be annoying. They connected easily to my iPhone and had descent sound for calls. They are not noise cancelling but they do muffle things quite a lot. The fit with the ear buds that came installed seem to work fine for my size of ears. Battery life seems fine, not super long but long enough for workouts for sure and multiple hours for other uses. They do seem a little pricey for what you get, but they are Bose after all :)
