$25 off. Haven't heard of the brand or used them myself, but they appear to be a decent little set of earphones for those who are in the market. Sound isolating seals. Tangle resistant cord. Father's day gift??? Other sites sell for $70 and up.

Headphones

nice find OP. There's a positive review for these on Amazon.

1Sandman said:The trouble is, THAT is the ONLY comment I could find anywhere for earbuds that no one seems to have ever heard of. To make matters worse, the kid that wrote it probably did not even have these, since he claims to be using them with his iPhone, and they clearly state that they are not compatible with the iPhone. They resemble the Vibe earbuds, perhaps he confused the two.

Are you sure it's the reviewer that's confused? How can any headphones possibly be not compatible with a PMP?

There are adapters that make any standard headphones compatible with the iPhone. The "reviewers" other reviews show the adapter that he may be using.

I was concerned that with only one review he could be a "plant" from the Lenntek company, but from the other reviews he has posted that did not appear to be the case.

I agree with being cautious of new names in the marketplace. For me the combination of Costco typically selling quality items combined with the reasonable price and good review on Amazon validated a purchase to see for myself.

Black was available yesterday in the dropdown. They may be out of it now.

I ordered them with the idea of returning them if they stunk. Got them yesterday. I will keep them. Similar to the Sony's in fit and feel, but a bit more sturdy. I like the wrapped cord. I am no audiophile, but the sound is great IMHO.

happyday said:Received mine today. The packaging and build quality is nothing special, but the sound is great. I would give these the edge over my Shure E2's that I have had for a couple years. Minus the fancy case that my Shures included. Though I may not describe the bass as "insane" like the Amazon review, I would say they do have a nice bump to them. The sound isolation gets the job done. Wearing them in the yard I could barely, if at all, hear my neighbors lawn mower.

In conclusion they may not be a familiar name brand, but if sound is your highest priority then you won't go wrong with these especially at this price. Recommended.

Thanks for the review. One question: how does the size (width) of the plastic "post" that actually goes in your ear compare with the Shures? I know there are different size tips that can be put onto the post, but I'm wondering about the size of the inner part itself. Thanks...

Thanks op, been looking for some headphones, will post the results when I get'em.

I know that some of the better headphones sound better after breaking them in after a few hours. Does anyone know if that's the case for these as well?

Just looking at the picture on the Costco website I would hazard a guess that these are indeed compatible with the iPhone.
