Not actually good for sports, sub-optimal audio quality
586943
As I anticipated when I bought this headset, most of what you're paying for is the logo.

The sound quality is not any better than a $20 set of headphones.

Also, I have a small head and I find the ear cups to too small to fit my ears comfortably.

If you press the rim of a coffee cup to your ear you'll get a sense for what it feels like to wear these headphones.

The product literature claims to fit one's ears perfectly, not taking into account that people of different ages, body types and ethnicities have radically different ear shapes and sizes.

In the pictures the pads look soft and comfortable but in reality they are actually quite firm and rigid.

The cable that comes with these headphones is also quite rigid, which is great for preventing tangling, but when I'm jogging the cable wobbles and flaps around and sticks out far enough that it repeatedly gets caught on my fingers, sending the headphones flying off of my head. To prevent this I have to shorten the cable by binding it up with a Velcro strap.

Lastly, the ear cups are closed. This means that when they're used for their purported design purpose, which is working out, I get massive ear sweat which causes my ears to itch and if I use them for more than an hour the trapped sweat causes ear infections.

To summarize, I believe these headphones are sold as "sporty" headphones, but that they are actually intended for people who do not work out at all, as a fashion accessory.

Signal-to-noise ratio is low. There's also a "pumping" compression when the source signal drops below a certain threshold. Very annoying when listening to material with high dynamic range, like movies. Because of this, I barely use the device. Would not purchase again.

Very low volume/gain, and terrible sound quality.

I had slightly high expectations for these ( I shouldn't have). It's partly my fault as I compared them to some very good headphones. They are well built, light, very comfortable and look good. They connect quickly and have no problem holding a connection. The problem is the sound, these will probably sound great to the average person walking into Best Buy. But compared to the sennheiser momentum, 598, and b&w p5 wireless they sound quite bad. Bass is lacking, treble isn't clear and they don't get very loud. I returned these and got the p5s, night and day difference!

I bought these earbuds to be either as a main set, or backup set. And it appears I'm going to use these as a backup set, since the audio quality takes a huge hit. Some of the issues I've been having is that the right earbud is louder than the left, which shares the microphone. Not only that, but there is distortion at medium-high volume, and it sounds really echoy and muffled no matter how deep I squish these in my ears. In addition to the audio quality being bad, as soon as I pulled the earbuds out, the entire speaker pulled out with it still connected to my ear, while I was able to snap it back in, it doesn't give me confidence in the overall quality. Aside from that the microphone is pretty good, people tell me it sounds like I'm speaking directly into the handset which is a plus, but it doesn't help if I can't hear them well back. In this situation you do get what you pay for, if you must have cheap earbuds with a microphone these are okay, just don't expect to have these for a while. I might try out the other model that is floating around Amazon and see how they are in comparison.

These headphones do function as described. They transmit bluetooth audio to your ears from a bluetooth equipped device. If that is all you are looking for, I guess go for broke. However having used these for a few days, I have returned to using wired headphones despite the inconvenience, as the sound quality is so poor and battery unreliable. This may not apply to all of you, depending upon your needs for audio quality.

Background:
I bought these with the intent of using while I worked out - whether running or lifting, wired headsets are a pain and I wanted an easier alternative. I thought I might as well try an affordable product to start and went with these. In the majority I listen to news audio podcasts meaning there is a fair amount of content transmitted over phone lines from reporters abroad. In past using very cheap (~$20) wired headphones, while on occasionally I'd have to re-listen, generally, the experience was enjoyable.

The good:
The headphones are easy to charge, easy to connect and do work as described. I was able to stream audio.

The bad (enough that I returned the product):
1. The volume was extremely finicky and too loud. Connected to my iPad I was unable to select a volume low enough that it was not hurting my ears, except at the very lowest volume at which it was too quiet. I ended up buying a 3rd party app to solve this problem, but even then couldn't control it from the headset in the pre-set increments. This is bad for content with a variety of volumes.
2. The sound quality was very poor. I could not make out many of the correspondents on the news programs I listened to and had to repeatedly rewind. This was the dealbreaker.
3. This I could have lived with, but they didn't keep a charge. Overnight they would frequently (though not always) drain even after being turned off so I kept them plugged in 24/7. Just another annoyance.

Combined these caused me to return the product, I cannot recommend. That said, if you don't care about detail in your sound, and can deal with loud volumes these will transmit sound to your ears.

I really wanted to like this Headset. It was Amazon's choice I believe. Drivers (under windows 10) are Pitiful, I only got to see the config screens once, and even after trying to find an updated driver online, they almost never open, and thus, the 7.1 audio, and other items including the equalizer are unavailable. As a Basic USB headset, it is "ok", the inline control works much like my previous headset, and I really like the reinforced cable. Lastly, the Audio Quality is somewhat lacking. The Bass response of these is very good, but the high end is not quite there, and the Midrange only comes into play when you hit 60% volume or so, overall, a very unbalanced audio experience. I am an IT Expert, so trust me when I say, I did try to rectify these issues.

UPDATE: they have responded to me and have helped resolve some issues, I have decided to stick with these for now

Pros: Durable reinforced USB cord. Easily accessed control box on cord, a little larger but it does not get in the way in using them. Great Bass response, also, have been told Microphone picks up bass better as well

Cons: Stick with existing Windows drivers for Win 10, Midrange audio does not come thru well until volume level is higher.

Neutral: Might work better for 7.1 with optional Dolby Atmos addon from Win 10 Store, Since I use these for gaming I am not as concerned about that vs the embedded directional audio now in most major titles.

I noticed a slightly lower audio quality than another device with a normal working headphone jack, but the difference is almost negligible - my music still sounds pretty good.
My biggest complaint is that the sound is a LOT louder than I want. I've set my system volume to the minimum (1%), which I never had to do before my headphone jack broke, and some sounds still bother me with how loud they are. At 100% volume I can use my earbuds as external speakers.
After a few hours of using this product I realized another huge flaw - the left and right channels are reversed, so I have to wear my headphones backwards to get the correct sound. This is a sign that the engineers were very lazy in ensuring that the product works correctly - the problem should be easy and inexpensive to fix, but it never was.
Overall, not recommended. Find a different product.

Great ear retention while running. Mediocre sound. Good price.

I am not sure if it is because I live in an appartment building or because I have power lines outside my living room window (I live on the 2nd floor so they're right at my level)or if people in my neighborhood use a lot of 900Mhz phones but the sound quality is simply awful.

My only purpose was to be able to play games on my Xbox without bothering anybody else so I am not even talking about an audiophile seeking crystal clear and rich sound, a decent sound clarity would have enough for me. Sitting no more than 7ft from my TV, sound gets cut-off and the static goes from bad to unbearable when you adjust the dial on the base. Same results with regular TV broadcast and when plugged into my laptop playing music.

I don't know if the product is bad or if my environment makes it work poorly but if you're considering this brand/model make sure  you have the ability to return it!

I guess I'll go back to my previous solution: standard headphones with a 15ft extension cable, which are fine since I don't need to be moving around.

Sound is good, but not superb, I love the controls! The battery life is crazy good!

It gets only 3 stars because the noise cancellation is seriously subpar.

I wear these comfortably at the Gym, and my hope was that these would mean I could block out "Planet Fitness' " radio channel, with it's bad music, without having to destroy me own ears with high volume. Alas this was not to be, the headphones noise cancellation seems to do little to nothing to tame the moderate volume of the Planet Fitness speakers.

Yuk, these things are ok for sitting on the couch, but for sports, forget it. The damn things don't stay in your ear and the sound is a fair. I use for running and hate having to worry about earbuds falling out. If they had fit properly, perhaps the music would sound better. I spend half my run trying to fit them. I found similar ones at Best Buy, cheaper and they fit your ear. excellent sound. I am keeping these for emergencies, or I may toss them away. Yea, that bad!

I have been looking for a headset to use with my iPhone 3GS that I can use while running. The earbuds provided by Apple are frustrating because they always end up falling out. So when I saw these I thought that this would be perfect for my needs. The feedback rating on Amazon for these was mixed but generally in the higher rating so I thought I would take the chance. Bad decision, the sound quality is poor and required me to set the volume at almost max to allow me to hear anything at all. They don't work well together with sunglasses and running hats, you need to have the legs of the glasses sit in top of the ear loops which then pushed against my running hat, not very comfortable. The next thing was the extender cable required to allow you to plug it into the iPhone.
The connection is poor causing intermittent sound loss in one or both of the earpieces, very frustrating!!
The earbuds themselves sort of hang down next to your ear and produce a very tinny output with very little bass.
Overall a very disappointing purchase and needless to say I am still on the look out for a decent headset with microphone.

The Bluetooth/wireless features are nice, but the sound quality is beyond awful. I didn't have terribly high expectations, but these sound worse than your average dollar-store over-the-ear headphones. The sound is tinny, metallic, and headache-inducing even before higher volume levels. Tried with multiple phones because I thought something was wrong with mine. If you absolutely crave the wireless features above all else, that bit works well. If you care about sound quality in the slightest, keep on looking.

For contrast, I own a pair of the $15 Amazon-branded earbuds and I think they sound amazing. It's not realistic to expect helmet speakers to sound anywhere near as good as earbuds, but these things were downright unpleasant.

Sound quality is not great and av jack for speakers are even worse.

Cheaply made. Not too comfortable when actually being active in sports for sports wireless Bluetooth headset lol. Low sound. They need to be upgraded with a better sound, made with more durability and to keep a charger longer than maybe an hour.

I've had these for several weeks now and feel I can offer a fair assessment. The two stars I give are for the sound quality. Surprisingly good, AS LONG AS I SIT IN ONE PLACE! But in motion? Nope... Just walking, not even running, the sound is FAR too frequently interrupted by the Bluetooth signal cutting out, making the music skip and blank out. It's a very annoying thing that happens even if I only turn my head to the left or right.

But possibly the BIGGEST issue is the fit - or lack of fit. These buds are way too heavy to stay in the ears. They are NOT good for sports. I actually doubled up the padding on the silicone tips to bulk them up, hoping they'd stay in my ears, but it doesn't work. These are just way too heavy to stay put. (BTW, you can't get replacement silicone tips anywhere in case you lose them). So - I will keep these for use around the house, but they are NOT for sports. At all.
