The first thing you notice when taking them out of the box, is how well the box has been packaged and the earphones presented. It fills you with geek lust at first sight, and that bodes well when you pick up the bullet shaped earphones which are made of metal, and not plastic. It feels solid and the 1.37m cable also has feels good. It's rubberised to reduce tangles and also insulates the cable well so that you don't get annoying interference when the cable rubs against your clothes, which is my pet peeve. The cable also has a mic and lapel clip so you can help position the cable on your clothes and speak into it. I'll be honest, I didn't test the mic. Sorry!
Coming back to the buds, they're made of aluminium and contain two small chambers in each of the 8.6mm drivers so help create a more enveloping, spaced sound, and reduces fatigue if listening for a long time. They come with 3 different sizes of silicon earbuds, and weigh 18g. You also get a soft leather like pouch with the earphones which is quite nice to hold.
The downside of this solid design is that these buds feel heavy in the ear when you first put them in. I was sure they'd fall out, but I soon got used to them, and no longer noticed them, even over prolonged periods. I do still prefer other designs though which stick out of my ears less.
Sonically, the Nuforce NE750M is good. I enjoyed listening to all forms of music and dialogue on them. There's no overwhelming base, and nothing ever sounded muddy. There's a slight over-emphasis of the mid-range, which does help in many situations, particularly dialogue, but it also leaves the higher and lower ranges sounding less solid in comparison. Where these do lack over more expensive earphones is in detail and separation of sounds. These never distorted, our sounded out of control, and didn't colour the music significantly.
At £80, it's difficult what to make of the Optoma NuForce NE750M's. I've enjoyed using them. They've always sounded good, they're well built, and have good quality cable with them, as well as a pouch. It's just that I can find similar audio quality earphones for about £50, and there's the rub. If these dropped down to a similar price, I'd whole heartedly recommend these earphones. As it is, it's a matter of taste. If you like the style, find the quality of the cable especially important, and want something different to everyone else, then you won't regret buying these, even at £80. If you're price sensitive, then I'd suggest waiting for these to drop in price.
