Not Good for Working Out
353086
Terrible. Fell out of my ears with the slightest movement. I tried all the rubber ear pieces, but nothing worked. I didn't think my ears were irregularly shaped, I don't have elf ears over here, but now I am reconsidering my normal ear theory. I do have to admit the few seconds I stood still and they remained in my ears, the sound quality was decent. Bluetooth works well.

Sound is great but I cant get the damn things to stay in my ear while Im working out. I end up spending half of my workouts trying to dig them deeper into my ear in hopes that they will stay. Super annoying.

These broke in the first week of use. I used them to exercise and sweat got in through the braids around the chord. Now they tend to turn the volume up full blast without me even touching the control and my ears are ringing horribly. They sound alright except there is too much bass, which doesn't go well with the genres that I listen to. Don't buy these if you plan on using them while running.

I ended up returning this item. It fits very awkwardly...similar to the product picture. Your breasts of any size will be smashed up and over the boning, creating a very odd look. Not something you could wear under clothing, not even recommended for working out it. Also the hooks create little gaps between and does not appear smooth under clothing.

I thought these would be great for exercising (I'm a runner), but I was so wrong!  They don't stay in your ears at all walking, let alone trying to jog.  I used them once, and they went in the trash.  Not worth the money!

Not good for working out, one ear tends to go out at times. Didn't use them for long. Also I would say these run in kids size. Very small

Don't buy if you plan to work out consistently. Do buy if you just want to look good. I purchased these on June 1st. At first they were tight fitting but they stretched out nicely to a comfort fit within the first month (a plus). I then fell sick and was out of the gym for almost a full 4 weeks in July. I was working out on August 4th and the blue palm grips started falling out. Still using them 13 days later and three more have fallen out. I workout, not including cardio days, on average 3+ days a week, 1 of which is a leg day that I wouldn't wear the gloves. So it averages out that I was able to get 8 or 10 workouts I get out of these before they started falling apart.

Only buy these if you are not planning to make the slightest effort while wearing them.... otherwise they fall out!!!
I got my avantree sacool couple of weeks ago and I was almost fascinated. These are good for running only. I read a bunch of reviews that you could used them while working out, but NO.
Everything was ok while doing moderate cardio, but then it came the tricky part. I started working out with these in order to keep my cellphone in my purse to avoid any damages while doing weights, but they kept falling off. They fall off at the slightest effort.  I tried all the different sizes of the different silicone ear buds and they kept falling off. I wore them according to the instructions and still kept falling off, which meant that I had to put down my weights arrange the earplugs and continue exercising ....this was annoying!!!! Until one day, I was doing dead-lifts of course these things kept on falling off, until the unavoidable happened.... they completely fell off and on an attempt to stopping them from completely hitting the floor, i had to drop my oly lift bar really fast which caused me to loose my balance the earplugs fell on the floor and of course I stepped on them. Now, I have completely lost all my money!!!! RIDICULOUS!!
If the product would have been as good ad they say ... it would never fall off and this accident could have been prevented. Now, I just wasted my money, I should have gotten something cheaper.

They're definitely not sweat-proof. The seal around the microphone didn't hold up on the control piece and the electronics fried. In addition the seal on one of the ear pieces was compromised and that went in and out as I sweated and then it dried. Not a great set for any real mileage. Maybe for 20 minutes at the gym it would hold up better.

The sound was pretty good, the battery life was good. The foam earbuds were REALLY comfortable and didn't seal like rubber ones do, so there was no WUB WUB from them bouncing around running.

The reception was good across a large room but for some reason wouldn't cross my body. If I had my phone in my left pocket and the button pod on the right side of my neck I would get signal dropout. So all in all I'd recommend them for light use or yard work, but if you really want sport headphones look elsewhere.

I am typically a medium. These do not work for running as I bought them for. Or anything active for that matter. They do not stay up with any moderate amount of movement. Even when lifting weights the top will roll down. Do not recommend these for working out! I am wondering if a small would have been any better. Ok for just wearing around the house and that's about it!

I was hoping these shorts would be good for working out, but they aren't and not even really comfortable for normal wear either.  First, they're a bit big, particularly in the lower tummy and stride.  They also tend to bunch and ride up when you get sweaty.  My main complaint, though, is the waist.  The flimsy mesh material, combined with the thin drawstring, leads to frequent rolling up around the waist.  I've tried wearing them to walk and to an exercise class and, in both settings, I was constantly pulling them down and trying to get them to not bunch up around my waist.  Part of the problem is my "love handles" (the rolls just invite the material to bunch in there, haha!).  I have other shorts that are elastic in the waist that don't bunch like this (usually they involve either a more complex elastic style or a sturdier material than just the thin mesh...or both).  Maybe if you're smaller and more fit than my XL self, it won't be a problem for you, but I find them extremely frustrating.

These earbuds deliver good sound but DO NOT stay in your ears well when doing physical activities. All it takes is the slightest movement and they dislodge from your ears and come loose, letting outside sounds in. I bought them so I could listen to music while I ran but they wouldn't stay in my ears.

Style is amazing but not good for working out. Spent the whole class pulling them up. And the fabric does not breath. I felt like I was running in a wet suit. I ordered three at once but I'm returning two of them because they are so impractical. Keeping one because I worked out in it. I will keep them for around the house but will never wear them to the gym again.

Forget wearing these if you plan on walking or working out. These will not stay in your ears and don't sound better than basic ipod earphones.

I sound quality is good, but purpose of this headphones was not served. I got it for my Workout and running. It was not staying in my ears. I tried all the fittings but nothing worked.

While These bras are soft and comfortable, they are NOT very useful sports bra. If you plan to work out in these you will have to double or triple up to keep your girls from bouncing away! Also -worst yet- the padding is a round circle that sticks out noticeably under your clothes. Awkward.

Disappointed.  Bad design for working out. The charging unit, because of it location made it of balance and awkward while working out. Whether walking or lifting weight.  The sound quality was bad.  There was a buzzing noise, that was constantly there.  Like a feedback from the battery.
