Summary: I had these Bose Sport earbuds for a few days, and I will say these are the most comfortable earbuds you can purchase. The Bose SIE2I's come with S,M,L stayhear tips which wont fall out of your ears no matter what you do. If you're jogging, sprinting, working out at the gym etc, you can rest assure these will stay put for the duration of your workout. The sound is clear, the highs are nice and the bass frequency not heavy, but just ok.
Summary: It's a nice fit in the ear. Never falls out during very active workouts. The sound quality is OK, but the level of sound isolation is zero compared to even cheapest headphones. I know it's not advertised as sound isolating headphones, but I guess it's not very tight in the fit, so you can hear people talking loud and clear while listening to music. My boyfriend has the model with iPhone controls and he has the same issue.
Summary: This extension is great one, I bought it because I didn't want my bose headphones cable cut off when sth happen, so I had an extension to reduce the cutting possibility. buying bose extension was because I wanted to guarantee the sound quality, not being affected by low quality wire. so, this is perfect.
Summary: i've tried loads of different headphones and i still cant find the ones for me and im not sure if i have with these,they aren't bad but they don't cancel out background noise which can be annoying.
Summary: Got these from another site in the end as I could collect them that Day. (had to have them that Day) Do not listen to people complaining that the sound or fit is not right, these are great for the gym. If you want a better sound then go spend a couple of Hundred pounds but for normal people in every Day life these are superb! Had a problem with noise leakage but once changed to the correct size bud problem solved.
Summary: After 6 months the left ear bud vibrated if too loud, then the other one fell apart (came in 2 ). I don't mind paying extra when items are worth it but sure don't appreciate paying good money for garbage. My last Bose purchase as I've heard from other claiming you are paying for their name.
