Suggestions for ear/headphones

I could not agree more.

I second this recomendation, i have been using these since i bought my nano..

I'm using Sennheiser also. They are great and stay in during speed-work sessions. No complaints after two months of using them.

I personally use the Sennheiser OMX-70 and have enjoyed using them so far. Thankfully they fit my ears and I don't have any problems with them popping out at all.

The sound quality is not what I expected from Sennheiser as the bass seems to be slightly lacking. Never the less I'm out to be running and as long as I can hear my tunes and not have to worry about the earbuds popping out.

If you're an audiophile but want a durable set of headphones on a limited budget, I strongly recommend the Koss Porta Pro.

I don't think you can get a better sounding headphone for less than $50 (I paid <$40 for mine). Read any review, you'll see that I'm not the only one who loves these. They're also designed to be adjustable and thus are extremely comfortable. Another nice feature is that they collapse into a ball, making them easy to travel with.

I would describe the sound output from these phones as being "accurate". Accuracy isn't something that everyone wants. Some people want artificially over-blown bass, which these don't provide. If you like hearing music the way it was intended to sound, you'll like these.

I wouldn't recommend spending more money to get workout headphones that are higher quality than these. Unless you're using canal phones, you won't hear the improvement while you're running anyway.

Happy to second/third the Sennheiser PX-100's. Earbuds still block out too much noise for me (I've already got 80% hearing loss in one ear, 20% in the other). Behind-the-head units never seem to fit, or fit comfortably. The PX-100's have fantastic sound, are not terribly expensive, and stay put during my runs.

The Etymotic Research earbuds are the best there is.
Don't let anyone tell you different.

I completely agree. The sound is spectacular, if you have the money. The noise isolation is amazing, I use them on the plane and it's like stepping into a soundproof vault. It should be noted that these headphones are vey uncomfortable for some people, because they are inserted into your ear canal. Personally I find the slight irritation to be outweighed by the superb audio and amazing noise isolation.

I am going to add and agree with most replies here. I have the Etymotic ER-6i's for my nano. I bought them new on Amazon from the new and used offering to my front door 85$. These are amazing. The sound quality is awesome and they are worth every penny. I went through 3 pairs of the ipod headphones due to listening and sweating at the gym...sweat would get in my ear and soak the earbuds...over time no more sound. Now I am not crazy for sound isolation headphones but now I can mow the lawn and listen to my music. They are not big on bass if you are a basshead. They take some getting used to ...you really have to jam these baby's in for them to work properly. If you really love music get a set!

Griffin EarThumps - made for iPod. great sound, nonslip, don't go down the ear canal. don't have the weird asymetrical cord like the Sony's, no trimming like the Etymotic's. I've run in them all, from $200 to $20 and these are the best. Simple, inexpensive - come in white or black.

Here is another vote for Sennheiser. My Apple buds would fall out too so got Sennheiser ear buds as they were given a good review for sound quality too. Sound is better and they have never fallen out running.
