I took Danners suggestion and went down a half size.  I got a good fit. Right toe box has noticeably less volume than the left boot, however this did mot compromise the fit.

Blackzebra HP-S1 Bluetooth 4.1 Portable Wireless Stereo Jogger Running Sports & Gym Exercise Headphones

If these headphones fit your ears they sound pretty good and stay put on your ears. I had trouble getting my left ear to cooperate with the left headphone. Its me, my right ear was fine with the mid-sized bud. My left ear was always out of alignment with the optimal hearing position. With the help of my hand I could temporarily adjust the bud so I could hear the music. It sounded great but I do wish it could go louder. I hit the top level, with the warning voice, and it just wasn't loud enough for good rock and roll. I also found the bass was lacking but that could be because I couldn't get a good seal on my ears, especially my left ear.

If they fit your ears, these are going to stay put on your head for exercising and other moving activities. The sound is decent if not stellar and you don't have my ears. These headphones work well and the remote is handy and capable. Overall they're a very good reasonably priced set of activity headphones.

This product was provided at or nearly no cost for the purpose of evaluation and review.

I had to replace my Altec Lansing Bliss Platnium ear buds, which had a great fit (too bad I lost sound out of one side) .  Since the Altec ones are no longer available, these seemed like the next best choice.  They are OK, definitely better than regular size ones, but still a little too snugly with the caps that they come with.  However, after I replaced the caps with ones from my old Altec Lansing buds, they fit great.  If you are looking for fit, try these.  You can get better sound quality from other buds, but great sound isn't worth it if your ears are killing from over sized buds!

So I've been on the hunt for some quality earphones that I can use while working out. And by working out I mean long winded workouts on a daily basis. Not the casual here and there workouts that most average reviewers practice.

With that said, I came across a few websites during my search that had these earphones at the top of the list so needless to say I went ahead and purchased them in hopes that I would be a happy customer.

I must note that prior to going on the hunt, I had been using the Monster Livestrong ISport Earphones, which, although not perfect, were far superior to these. But in the end I lost them during a trip recently. They are now discontinued so I am now left to find something new.

So onto the review.

Package was decent enough but nothing special. Earphones come with various sizes of ear inserts that attach to the actual earphones themselves so finding a good fit shouldn't be a problem.

The wiring is a bit flimsy and where it attaches to the actual earphone is somewhat fragile. Although it didn't happen to me in my handful of usages, I can see how over time (not very long at that) the wire could fail from the earphone and either break or lose connection. Most earbuds I've had have a relatively rigid wire at the point where they actually connect to the earphone.

When I put them into my ears It almost felt as if they weren't in all the way. The outer rubber ring is supposedly supposed to secure the earphone to your ear by pushing up against that little bridge of cartilage that runs along the outside of the inner ear. To me, it didn't feel like it was big enough to be pushing up against my outer ear. But during my run during an actual run it miraculously stayed in little to no adjustment required during the entire 3 miles that I ran. And it also felt pretty non existent as others reviews have stated. So in terms of comfort, I definitely give it props as it not only stays put during rigorous activites but it also almost feels like it's not there.

Sound quality was nothing to rave about but was probably about average given it's size and isolation style. However, while running, the wires did bounce quite a bit and the resulting noise from that managed to obstruct the music. I was able to somewhat resolve that issue by using the wire clip to attach to my shirt.  Ambient noise is pretty apparent as well. These earphones aren't meant to block out surrounding noise so if that's what you want then you're out of luck. That or you just max out the volume to hopefully drown out any other noise.

The biggest issue I had with these is that the inline remote wiring was extremely faulty. I may have gotten a defective pair but I need to share my experience nonetheless. On my first run with these I used my newer Ipod Nano. As I started running I immediately noticed that the songs kept on skipping randomly. At first I thought maybe I had the nano set to shuffle when shaken but that was not the case. It kept on doing so until I finally clipped the wire to my shirt to lessen the bouncing of the wires. That helped somewhat but every so often it would still skip spontaneously.

Second run, I decide to use a different older model of nano thinking that it might be an issue with the player and not the headphones. This time around it was worse. Skipping, volume changing, pausing, unpausing...it was basically all over the place. On top of that, the right earphone was going in and out.

In summary, I think the design is great for the purpose (running, working out, etc.) however, the audio and functionality are totally non existent. Even if the wiring on my unit was defective I can only see that a working unit would eventually go bad based on the flimsy wiring alone. I'm no audiophile as well but I just thought that the sound was subpar for headphone at that pricepoint.

Anyhow, I don't recommend these headphones as there were easily more negatives than positives.

I'm giving this four stars because of the fit. Personally i find the inner red part of the bud tips are too stiff, which in turn causes a blocked ear effect when listening to music in my right ear. Changed out the bud tip with a samsung one and now it works perfectly.

Otherwise

-Nice, clear loud music
-Fast pairing and connecting
-No more wire bump sound (praise the Lord)
-Built in volume on the headset itself in addition to your handset volume makes it excellent for drowning out loud noises when travelling

edit/update

Upon closer inspection and looking at the angle of the ear tips as compared to my other headphones, it has a slight angle that makes all the difference in the world. Let's say that my samsung headset tips are straight, these are at a 15? degree angle give or take that causes the uncomfortable fit and extremely muddled sound. so beware of that

They're ok. I bought these for inconspicuous use at work, so I don't know how well they will perform doing active things like biking or walking my dog. The hardest part by far was finding a good fit. I have little overall ears, and the small wings were on the edge of being uncomfortable.  I had to get altogether different tips because the ones that came with it did not create a good seal.  Once I found a somewhat reasonable fit, the sound kept traveling off to one side, and I know that my music has proper balance. Sound quality is nowhere near what I've been used to with my Jbird Bluebudz which are over 2 years old. Almost no bass. Sound quality is likely related to fit though. I'm still on the fence whether or not I will keep them. Battery life is on par with what I'd read, so far, for streaming music, about an hour and a half. I haven't loaded music directly onto the device yet.

Toe box on right shoe was much smaller than left shoe.  This caused the foot to go dumb and eventually right leg issues.  Disappointed as I have worn Asics for years but find that every pair that I have tried recently fits different.

I apparently have tiny ears, so at first these were uncomfortable. But then I cut off the top tier, and now the fit is perfect! I get good sound, a good noise canceling seal, and they are comfortable to wear!

These seem slightly smaller than the original N1 V1's that I love.  Toe box seems more narrow and shorter than the original I am having a hard time finding the size that I think will fit correctly.  Seems like I am 1/2 between a 9.5 and 10 (where the 9.5 in the original fit perfectly).

I do like the updated look. The shoes cushioning feels great.

Contrary to some comments here I feel the fit is more secure and comfortable than the previous model. Although they assign a Left and Right you can actually use them in revers and may be more comfortable.

Very effective when you are active, want your ear to "breathe" a little (unlike in-ear) and have some awareness of external, ambient, sounds.

I loved the sound signature of these earphones, and it's one of the best bang for buck earphones at this price level. However, the fit felt very off on the right earphone. No matter what tips I used or how I tried wearing the earphone, the right earphone never fit well and actually hurt after 15+ minutes of wear. There's an odd intentional rubber bump on the right earphone that I could never get used to. It's a shame the fit didn't work out for me as these were some of the best headphones I've ever heard at this price; huge soundstage, very balanced signature with a little emphasis on bass.

Altra has changed the volume of the toebox, again. They do this every year, so I'll have to buy ten pair of these. This current last is a little shorter in the middle toe area. Probably to reduce the weight of the shoes. This seems to be the same last as the Paradigm 2 and the Olympus 2. Luckily the LPs seem to have a better fabric than the new Olympus. Overall, these have withstood one run of 20 miles on single-track. I wear a size 12 w/ Morton's toe.

Maybe you'll have a better experience. Even though the liner in the right shoe is slightly askew (I've tried to adjust it), I still like the shoes. They are comfortable and provide decent support. The shoes look good too.

toe box is a little narrow and low. hits on my big toe, but after a while it's not so bad. Needs more support to be Dr. Scholl's for me.

The fit was good on the left foot.  I have problem with my right foot that makes it difficult to fit a shoe.  I think the C/D width would have been a better choice.

It has a tight fit in the toe box and it looked more comfortable than it felt. It was not for me , at least.

So I came to these tips having previously used the Comply TSX-500 Comfort Plus tips (size Medium) with my JayBird BlueBuds X headphones.  I originally tried the medium size of the Sport Plus tips but found that they were far too loose in my ear, so I ordered the larges.  They fit fine, but the seal is no where near as good as it was with the Comfort Plus tips.  For example, where I used to be able to have the volume on medium while mowing the lawn with the Comfort Plus tips, with these I have to crank the volume, even with the large ones.  I'm pretty disappointed with them and will probably just buy some of the Comfort Plus tips again at some point (my only gripe with them was that they would get "sweat lock" during long runs ... where one of the earbuds was plugged up with sweat and no sound came through).

As others have said it is a bit of a pain to get the tips on but once they are on its no longer an issue.
