AUGLAMOUR is a known brand, both for their unique designs and their excellent sound quality for the price. The F100 are one of their cheapest models ever. I was expecting plastic housings and cheap sound, but was pleasantly surprices to receive a well-built pair with a great sound quality for a relatively low price. Except for the springy/sticky cable with the cheap inline remote that remind me KZ earphones, the earphones themselves, the Y-split and the 3.5mm plugs are actually all metal and quite well-made.
As to the sound quality - quite surprising for the price. The sound is mid-forward with a lot of mid-bass, but not to the point of being muddy. The highs are detailed, but also have somewhat harsh timbre which I could notice on certain tracks. The sound is close and intimate rather than spacious, hence not quite immersive. Still, for their price and the single dynamic driver setup, the sound is quite excellent.
Although they were designed to be comfortable over-the-ear style earphones, I didn't find them straightforward enought to wear. They are heavy and quite thick for no apparent reason, and for them to be comfortable you'd have to use the included ear loops.
Lows / Bass
The lows are well-controlled and not exhaggerated. For many listeners, that bass will be enough. For me, however, it's not quite what I like. I get the feeling that the bass is subdued behind the loud upfront mids and I can't feel its impact on bass-heavy compositions.
Mids / Vocals
The mids are highly emphasized in the upper-mids range - a bit shouty and intimate. Vocals sound as if they are coming from above, rather than being in front of you. There are many fans of this kind of sound, but I usually like my earphones more surrounding and spacious. With that being said, the mids are quite excellent, especially for the price. They are loud and precise, maybe slightly too edgy for my taste.
Highs / Treble
The highs, while quite emphasized, are not the best I've heard. Placing these highs against some hybrid earphones (and even a few dynamic driver earphones), the highs lack that microdetail and crispness that I got used to. The treble isn't piercing, that a huge advantage, but also not tonally pleasant, at least for me. There's a metallic tint to it, and some frequencies seem to be more emphasized than what I'm used to, creating a weird and somewhat harsh sound on higher volumes.
