In-Ear Noise Isolation Earphones with EXTRA 1PR of 3 flange earplugs (similar to Etymotic ER4 and ER6) for the ultimate sound isolation! These have been custom made to be a Y style cable (both L and R cables are even length).  These are now customized for the Apple iPhone with a built-in microphone to allow for HANDSFREE calling.  The handsfree comes with a button below the microphone to control phone functions (accept/end) and iPod functions (Play/Pause, next track), so you will not lose out on any features.

Don't settle for 2nd rate sound from Apple's pack-in earphones that came with your iPhone.  You didn't spend $400 on a device just to get sound from a pair of cheap earphones, right?  Until today, you had little choice in the matter.  Either buy V-Moda Vibes Duo at $100 or buy an adapter from Shure for $50 and have a wiring mess.  Now, you can enjoy awesome music fidelity and the benefit of a noise-isolating handsfree all in one, and it won't cost you an arm and a leg.  The original version of these earphones are some of the best around for under $100, and now we've made them even better suited for an Apple iPhone. They are made by the world's largest earphone manufacturer in Japan. This model has been sold under many famous brand names, including Sharp MD33 and Sennheiser CX300. They also supply to Nokia, Sony Ericsson, Apple, and many others. So rest assured that you are getting only the best of the best. These are brand new in OEM packaging.

These drivers are 100% identical to the CX300 coming off the same assembly line in the same factory using the same components. Read the feedbacks and buy with confidence!

These in-ear earphones are designed with ergonomic soft silicon in-ear earplugs for excellent noise isolation (over 20db when properly inserted) and offers natural high-quality audio reproduction throughout the entire frequency range. One awesome feature about these earphones is that they have extraordinary bass lacking in the original iPod earbuds and many others many times its size. These earphones use state-of-the-art micro Neodymium drivers and OFC (oxygen-free-copper) cabling and upgraded straight gold-plated plugs to ensure optimal music reproduction and transmission.

These earplug earphones offer passive noise isolation which rival many active noise cancellation earphones, but at a fraction of the cost without using batteries. Included in this set are 2 other sets of silicon earplugs to fit different sized ears. This earphone will perform very similar to the Shure E2C's but offer much better bass performance.

To ensure optimal fit, please use the largest earplugs that are comfortable. In the beginning, it should feel even a little tight. This way, a proper seal can be created to block out external sound and provide optimal bass response.

Users that have complained about a lack of bass have not been using the earphones correctly. These MUST be inserted into the ear as far as comfortably possible. When you insert these earphones properly, you will know because all of a sudden, external noise will be reduced to a level you have not experienced before.

These little pods won't disappoint! Like the review before me, I've searched far and wide for the perfect sound and price point, and at $49.00, these unassuming plugs are IT. Balanced sound all around, good highs, lows, and mids, and purty to match. Sound great through my 3rd Gen iPod, which is something I can't say for a lot of phones. I've had a set of Sony EX71LPs and these destroy the sonys in sound and value. I highly recommend for a portable solution. ...
