[This review was collected as part of a promotion.] I bought Bose QC Ultra Earbuds last year and I'm very satisfied from my choice.

[This review was collected as part of a promotion.] Favorite office and walking buds! An absolute game changer for me.

[This review was collected as part of a promotion.] Love the sound quality. You need to adjust your sound settings.

The ear tips seem to fall off a bit to easily. I recently took them outdoors and had a lot of wind noise while walking. I did not have that issue with my previous Bose earbuds.

Great sound, great battery life, and better for my ears as the open concept allows them to breath. I'm surprised by the sound quality as they don't actually go in my ear.

I bought it about 3 weeks ago, and I love the pure sound and the noise canceling, however the ergonomic shape i found a bit bigger for my ear, doesn't fit perfect and I'm scare to lose at some point.

This is another great Bose product. I was initially concerned that the design would not hold the buds in place while I run but that’s not the case. They are very secure once they are on and again, the sound quality is excellent.

I've never heard better. They've never fit better. Absolutely amazing sound. I've had Bose Bluetooth speakers, PC speakers, but this is my first pair of ear buds. Always searching for a better sound, I know I've found the best.
