do you have them longer, if so how long do you have them

I've only seen the one length, but it's quite efficient in picking up channels.

Hold long they last really depends on your usage of them as this varies from person to person. We will be offering replacement heads for sale next month.

I don't remember now, but they are pretty good quality, I think they will last longer.

They don't bother me, but I usually don't wear them for extended periods of time. More than 10 or 15 minutes at most.

I believe they are supposed to last for one year. I have been using mine for over 6 months now and it has barely changed in size.

I keep mine on for 30 minutes a day anyways. i just figure the longer they're on the better. 5 minutes seems a bit to quick to me.

Keep 'em clean and they should last much longer. I'm at the 6 month point right now and they are still working really well.

Yes I am pretty sure but they last longer than regular ones. So it's worth it.

I do not have them where I am but if you can wait a week or so I should be able to measure them.

Not sure, I haven't had it long enough. However, they might be easily replaced if they got too bad.

They were quite when I received them and tried them out. I do not know as they age. I gave them as a gift.

They last quite awhile actually. I change mine out weekly, even though I never see more than minor wear on them.

I did after about 2 months, but the holes in them aren't much different so you could use them from birth if you wanted. I would have done that if I had known their wasn't much of a difference. Saved some money : )

If you take care of them they'll last forever. I clean them with a soft toothbrush after I use it and keep it in the case they give you.

I borrowed them out and do not have them back yet. I am not able to tell you.

I've only had mine for a month or so. However, I'm certain it depends on how often you use them and how well you take care of them after and between each use. I expect mine will last longer than 6 mo. as I don't wear them constantly.
