I listen to a variety of music, and have high quality listening devices in my office and other headphones i use for quality sound. I bought these knowing Bose mix bass heavy for perceived quality, fine with me as these were to be my workout headphones.

The battery is excellent.
The sound is good for what you pay. Not particularly honest but a good mix across the range.

But...
The build quality is simply horrendous for what you pay.
The Bose logos fell off within 6 months what ever didn't bother me but now the rest of it is starting to fall apart.

If you want something to last a few years then just don't buy them it's not worth it. Has put me off any of their higher end products for sure.

Less than one year old totally fell apart .build quality is poor and battery life no where near stated .Sound is good, but no way they worth the money. Very disappointed

These are the best headphones I’ve ever owned. I use them multiple times a week at the gym. They are still in good condition after about 2 years of use.

Pros : good sound quality. Perfect wire length.
Cons: gets disconnected even when there’s no obstruction and phone is right next to you. Wire becomes sticky on the neck while in gym. The ear pieces look a bit awkward protruding out of your ears when u look straight on the face. No magnets in the earbuds. Battrey life not as per advertisement.

Pros:
Good sound quality
Cons:
Pricey

It's the best wireless headset you can buy in the market but bit pricey compared to other brands. One concern is that it does not support aptx or any other hd formats

These little morsels of goodness are like a personal cloud of music following you throughout the day. Of course they are lightweight but the tech they have crammed into these little ear huggers is amazing.
The battery life is pretty good (need to charge them daily if you are blasting them for 8hrs in the office but that is reasonable given it's size)
Bose support is always amazing too. I have always trusted this brand because of their support.
I highly recommend the Bose Sound Sport Wireless Headphones.

Purchased these approx. 2 years ago primarily for music while running & also voice calls etc. I've found them fantastic. Very comfortable, never fell out of my ears, great sound quality for a wireless earphone - have done the job until recently when the rubber started breaking and flapping around the ear pieces. I was a bit miffed but figured after 2 years i wouldn't get much help - to my great surprise Bose advised they've extended the warranty and are replacing them outright! I expected a bit more than 2 years out of the first pair but did not expect a full like for like replacement so very happy Bose customer here! Great product that they stand behind so can't ask for much more.

Overall great set of headphones.
Sound quality is fantastic and the battery life is more than adequate.
An issue did arise with the headphones after around two months of use, where the turn off button stopped working and the volume/skip buttons were not responding.
I took the faulty set to the Bose store where they were purchased and they replaced the headphones with a brand new pair on the spot without any issues.

Above Head phone features and service simply great. Excellent performance and sound and clarity is too good. Frankly very safe to use without harming to our ears in any manner.

The Bose sound sport wireless headphones are small and easy to carry. They fit well and work fine, however there were a couple of times when people told me that the background noise was too loud. So I guess I’m happy with the product, but if you have an important call to make or even a meeting, then don’t use them.

I have B&O, Apple, sennheiser and sony earphones and i always go back to bose. I have this particular one for long time. Used it for gym, travelling, at home or on the go. Sound quality is really great. It fits well into my ear. Choose Bose if you want a top quality of earphones

I really wanted a good pair of wireless headphones for the gym. I'm quite disappointed. I find they fall out of my ear constantly (especially if i lean down to pick up weights). I've tried the different sized ear pieces but to no avail. Sound quality is good. Battery doesn't last.

Excellent sound quality as expected from Bose. These headphones sit nicely in the ear, and the soft silicone ear pieces keep them gently but securely in your ear. Good for sport or general use. With 3 different size ear pieces, you're sure to find a good fit. The little carry case they come with is lightweight, high-quality and very cute.

The range of these earphone is great, they have never failed when l have been exercing in the gym.
They are comfortable to wear and don't fall out even after heavy exercises
The sound from them is very clear as usually is the case with Bose products.
I cannot fault these.

Best sound quality and great fit. Solid connection. Compact bag is very handy to store headphones. Bose application is very handy. It updates headphone firmware to latest automatically. Never got a drop in Bluetooth connectivity. Sound quality can't fault it. Tried jabra but bose is the best wireless at the moment.

It's Bose so no doubt the sound quality is really good. They are comfortable and great to use while exercising. Have used sony's earphone but it's easy to fall from out ear, so I keep coming back to Bose. Highly recommended for people work out a lot since it is super comfortable and easy to clean.

It's Bose so the sound quality is second to none. They are comfortable and great to use while exercising. Have used other brands but keep coming back to Bose. Highly recommended for people walking, running or bike riding as they are super comfortable and easy to clean should the need arise.

As a sports headset, I think this headset is already pretty good.The main thing is that it's really comfortable to run and ride a bike.And the sound quality is great!At least the dynamic type.It takes three hours and a grid doesn't go away, nothing happens, and it's really, really good to brag about the bass.This headset is totally fine.Use different headphones and players according to different needs. This is the way to ensure sound quality.
