Sennheiser CX680 Adidas Ean-Canal Headphones with Volume Control
Can you remember the last time you had a proper workout without any disturbances from the blaring gym radio, falling earbuds or clatter of machines? The new Sennheiser/Adidas CX 680 sports earphones will change that on the first listen. These sweat-proof, noise-isolating ear-canal 'phones deliver outstanding, high-energy stereo sound while blocking out up to 20 dB of gym noise.
The exclusive EarFin provides a comfortable, secure fit that won't fall out during your workout. Further, the CX 680 can be adapted to fit ANY ear using the supplied fit kit. This will ensure long-term comfort and exceptional isolation to enhance sound quality and concentration. A convenient volume adjuster keeps you in control of your tunes while a detachable extension cable lets you position your MP3 player where YOU want it.
The DuPont™ Kevlar® reinforced cabling guarantees durability and flexibility where other sport headphones can't - even in cold temperatures. The sweat-proof, water-resistant construction lets you go your hardest during any off-season.
iPod and iPhone are registered brands of Apple Computer, inc. in the USA and other countries.

Stays in, but awful sound quality
By Bobbie from Springfield, VA on August 3, 2010

If you want an earphone that stays in while exercising, this one does indeed perform. However, the materials used are all very cheap plastic, and the sound quality was terrible. Unfortunately, when I went to return it, I discovered that there is a NO RETURNS POLICY on all earphones that are inserted into the ear canal. So, how do you know if a product such as this works until you try it? Bottom line, is you don't, and you are stuck with it.
My earphones are now part of a landfill. Stick with Shure - they may have to be reinserted several times during your workout, but the sound quality is awesome!
Pros:
Stayed in the earCons:
Cheap plastic construction, flimsy sound control adjuster, terrible sound quality, NO RETURN POLICY for any in ear canal headphones.Merchant Response:
Dear Bobbie,
Thanks for the feedback.
We do offer a 30 day return policy on brands that support the same for us.
Because these go inside your ear canal we cannot sell to you something that was returned to us and that is how we guarantee our customers brand new items.
In the case of Sennheiser, they are not supporting at the moment returns of products that have been opened. Although they continue to be 100% covered under warranty and will be replaced at no cost if anything goes wrong with them.
Most of the other manufacturers we represent support our 30 day return policy (Shure, Westone, Klipsch, Audeo, Monster, etc.) so if you buy one of these products and they don't work out for you we will either process a refund or an exchange in accordance with our 30 day return policy.
The exception of Sennheiser earphones is noted on our policy.
As soon as Sennheiser changes that and start to support our return policy, we will extend the same to our customers.
Please make sure you are getting a good seal with the CX680 because if you are not, they will sound tiny. I have tested them myself and I can tell you they sound amazing but you need to have the right eartips for your ear canal shape and size and that takes some time.
Please feel free to contact us at 1-888-473-9661 for any help and again please accept our apologies for this inconvenience.Finally an earphone meant to be worn in real life conditions

I was surprised and pleased that Sennheiser took the time to get the ear canal phones right! They feature some sort of "wing" that keeps the earphone firmly planted in the ear canal without the feeling of excess pressure. The small caps on the earphone electronics are constructed to keep sweat and earwax from penetrating the device and a sponge filter further protects the internal parts from fouling. And the kit includes replacement filters. The attached clip and volume device are positioned to allow the cable to be placed behind or in front of the ear. The cable is long enough to place my iPod in my pants pocket without pulling the cable from my ears. And the sound is great (and I am a fanatic for good sound) - as good as any pair I have ever tried, including the competitive models costing $150. Lastly, the cable is bright yellow which makes it easy for my tired eyes to locate across the room. I give this product a definite A Plus.
I would recommend this item to a friend.

Thanks for the great review Jim!the worst earphones I have ever owned
By nils from b.c on May 22, 2010

All they do is fall out of your ears and the cord set up for the phones really sucks.
Great store to deal with and really fast shipping. Will definitely deal with store again.
Merchant Response:
Dear Nils, please make sure you follow the instructions on how to fit them as these are quite different than all the other models due to the "ear fin" feature they have.
Thanks for the review! Cumpre o que promete
By Alexandre Almeida from Belo Horizonte - MG, Brasil on April 20, 2010

Excelente produto. Qualidade de som muito boa. Não é excepcional mas é o bastante para o preço que tem. Melhor apenas os topos de linha, a aproximadamente U$ 450,00. Para prática de esportes é insuperável.
Pros:
Conforto
Qualidade de som
DesignCons:
Não oferece controle para mudança de faixa de músicaI would recommend this item to a friend.
