Looking for great-sounding headphones that can stand up to a demanding workout? Bose SIE2 sport headphones are comfortable, sweat-resistant and durable, so they can follow you to the gym, on the trail or anywhere in between. They may be tough, but they'll handle your music with care. Bose's exclusive TriPort® acoustic headphone structure delivers rich, full sound that will keep you moving. The proprietary StayHear® tips make sure these headphones stay put, even when you're in constant motion.

The Reebok® fitness armband

The SIE2 sport headphones come with an exclusive Reebok® fitness armband, so your mobile device stays safely secured while you're on the go.

  • Sound Quality

Excellent headphones. I have been using the headphones daily to work out and they provide excellent sound while staying in my ears through any physical activity. The armband is perfect for running and the extension cord allows me to place my ipod in my pocket when lifting. The overall functionality of this product is exceptional and you know the sound will be good from Bose. Great purchase, I strongly recommend.

Pros: Sleek, sound quality exceptional, functionality

Cons: Noise reduction is not perfect but I am used to active noise canceling so probably just me

Product Research


Overview: Bose SIE2 in-ear sport headphones are designed specifically for exercise, both indoor and outdoor. They offer the same audio performance as other Bose in-ear headphones, but can withstand the rigors of an active lifestyle. They have been optimized to resist moisture from the weather or from sweat. The StayHear silicone tips fit comfortably, but snugly into your ear, and are designed to stay in place during strenuous activity.

StayHear Ear Tips: The SIE2 headphones include three sizes of silicone ear tips (S/M/L) to assure a more accurate fit that's comfortable and stable. Advanced materials and design allow the tips to nestle inside the bowl of the ear, while also naturally conforming to the ear's upper ridge. StayHear tips also are designed to remain more securely on the headphone, as well.

Note: You should not attempt to wear the headphones without the ear tips.

TriPort Technology: Like other Bose in-ear headphones, the SIE2 sport headphones feature Bose's acclaimed TriPort technology. The headphones deliver wide-range sound, with deep, natural lows and crisp highs. Even though they are in-ear headphones, the SIE2 are not noise-canceling. They are purposefully designed to keep you aware of your surroundings while you are running through busy city streets or highways.

Cable and Extension: The SIE2s have a 32" cable that's long enough to reach your portable media device, and short enough that you're not constantly fighting excessive length. A clothing clip is attached to the cable so you can keep it out of the way. If you need additional cable, a 21" extension is included.

3.5mm Connector: The headphone cables have a slender, straight 3.5mm plug that fits directly into most digital media players, including iPod and iPhone models (including the iPhone 5) with hard cases, as well as laptops and portable CD and DVD players.

Armband: Included with the SIE2 is a matching green and gray Reebok fitness armband that holds your device during exercise. It can hold your iPod, iPhone, or most any portable media device. It has a clear window to let you see the device's screen and operate the touchscreen controls. There's also a separate pocket for your keys.
