Review Content Very Nice Great sound, fit well in ears. Nice product Great for workouts and calls Great fit and comfort when Im working out. I like that I can control my music from the touch of a button (although I had to learn how to operate the button -one push, push twice, etc). I really like the quality of the sound and immediately noticed the difference in quality Also comes with an extension and different sized ear pieces to ensure fit and comfort Excellent headset! Great for walking/running and using my iPod. Another solid performance from Bose I has everything a sport headphone needs to have, and more. It doesnt make you feel uncomfortable while gripping to your ear. Secure Fit I love my new sport headphones! I sweat a TON when I run...and these buds dont slip out...dont move at ALL. First ever. Im tempted to buy a second pair to have a spare! Bose Ear Buds Superior to the Apple ear buds. Fits into ear comfortably, not loose during sweaty workout. Great sound and comfort. Only drawback is the 2-piece design to earbud. It is possible to lose part of the ear bud if pulled out of pocket or gym bag. Niece loved it! Got this for my niece who lives in NYC, she loves it, used it on the plane ride home and every day since on the subway and at her gym! I Use Them All the Time This has become my favorite to listen to music and podcast of about 20 similar products I own. They never hurt my ears no mater how long I wear them. My highest recommendation. Does the job. I purchased the Bose SIE2i sport headphones because I needed headphones specifically for use when jogging. I went through many headphones, from top brands to cheap 99 cent stuff and the problems I had with previous headphones I do not have with these Bose headphones. Some of my other sport headphones would literally shock me when my sweat would make contact with the headphones, they would slip off, or the wire was too long just to name a few. With these headphones, they definitely do the job I was looking for and they also have a great sporty green look. My only complaint is the armband that comes with the headphones. The armband itself is tight and the pocket to place your iPhone is cumbersome. For starters, if you have a protective case for your phone, you do have to remove your phone from the case to fit in the armband; however, once in there, it does fit in very snug. Unfortunately, my bigger issue was the armband. The armband is probably best suited for someone with smaller biceps. My biceps are about 1 Great sound and fit well in ear Great for exercise and iPhone use Bose Earbuds Cant put phone in pants or jacket pocket and use earbuds becasue the length was made to strap to arm.
