Cons: Sound quality, comfort
This is my first review here.
I bought those "gems" today. After some hours of burn-in I tried them with great expectations as I already had a Philips older model that I found not perfect but at least easy to listen. Well, don't believe what people on Amazon say, this unit is a big big stay away.
Simple, but looks good, the 12hz-22khz mark promises much. Comes with a nice bag to store it in, and some rubber plugs to fit all ear sizes, for me the second small one worked the best.
Bad. As simple as that. The rubber thingies are not made of that well known thin material but rather thick, and that comes to discomfort immediately. You can't insert them to your ears exactly right, and even if you push push push for some time they are just trying to shape your ear canal to their own shape. I'd get headache in an hour for sure. You'll never experience the "it's not even there" feeling here for sure. I'd say comfort is 1 on a 10 scale.
The sound is playing in the league of chinese crap that you can pick up at a few bucks at any store. Maybe sounds better than a few percent of those, but does a good job on getting close. The bass rolls of at about 40hz, don't expect any sub bass tones at all. It also extends pretty high and would render higher tones dull in case there would be anything else then shouting mids. Take a reguler landline phone, imagine the sound coming from it extended with some bass and that's what you get. Shouty mids and almost no high end. I'd say highs end at about 12khz at best. To all of that add that it really sounds all tones are cming from a box. Clarity? Depth? Positioning? These are unknown here... I am very very dissatisfied. Surround sound? Coming from where? It can't even play simple music with normal quality.
If they'd give this away free with MP3 players this would be the unit I'd suggest to replace immediately, as you get better sound with almost any other option. I do not recommend this under any circumstances. I am really close to throw this in a trashcan keeping the worlds most expensive headphone carry bag only, that looks usable.
