The NE-700X earphones from Nuforce have a solid, well balanced sound and they present with a very sophisticated look that should particularly appeal to adults. The color is called Aqua Silver.
The stereo earphones work all versions of the iPhone except the first generation and with any other device that supports 3.5mm stereo in 3 or 4 pin plugs. The driver size is 8mm, the frequency response is 20 to 20 KHz, the sensitivity is 105 db +/-3db, and the rated power is 3mW.
The package includes the stereo headset, three pairs of single flange ear-tips (two each of small, medium, and large size), and a carrying case. There is a one year warranty. The MSRP is US$65.00. I did not find any cheaper prices with an Internet search, but I did find it at Amazon.com.
The NE-700X does not include a microphone although Nuforce offers a companion product that does include a microphone in the NE-700M. That product sells for US$75.
Using the product
I found the earphones to be comfortable to wear during the several hours I spent testing them. They stayed comfortably placed in my ears which is always a good thing. Following advice I found on the web site, I looped the cable around the ear (from front to back) while walking. That completely eliminated the rustling noise which was present while walking — until I tried this trick.
I thought the base was well balanced and it provided a good presence without being intrusive. The treble was smooth and clear and the mid-range sounded natural.
Do I recommend it?
I do. I like the look of this product and think any business person would be comfortable using them during a business day. The earphones stay in place — always an important element. The sound is good, particularly for the price. After testing them, I was surprised that they do not have a higher MSRP.
