Packaging and content.
Packaging is easily accessible and thoughtfully made. Inside the box you’ll find S/M/L/XL and biflange silicone sleeves, three pairs of tuning plates, a zippered soft case and an airlane adapter. All in all a generous amount of accessories, even if there are no foam sleeves or cleaning tool provided.
Build and build quality.
The first thing that strikes you when you see them is how small they are. The housing itself is made of metal, which gives a nice solid feel to it. The lightweight cable is 120cm/47in, and has a 45 degree angle on the jack, it also has a clip to secure the cable to your clothing. Holding the Quattro's you get the feeling of a high quality solid product.
Comfort.
The Quattro’s can be worn either with the cable running straight down or over the ear. The size and the choice of how to wear them combined with the many different included sleeves makes the Quattro’s exceptionally comfortable to wear, you simply forget they are in your ears. Isolation from ambient noise is quite good, the cable suffers from some microphonic noise but this can be minimised with the clip or wearing them over the ear.
What about the sound?
The Quattro’s use a 7mm dynamic driver coupled with a bassport and the tuning plates already mentioned. Sensitivity is stated as approx 95dB/mW and impedance as 16 Ohm, and I can happily say that I can't hear any hissing. I have now put some 40 hours on mine and the bass has settled nicely as well as the highs are opening up more. The tuning plates provide different amounts of warmth to the sound, from the bassy number 1, via the more neutral number 2, to the nearly analytical sounding number 3, or if you are daring you can use them without the plate (just be careful not to get water inside the housing), which makes them sound more like high end open back full size headphones with prominent bass and a very wide soundstage. My personal favourite is to use them without the plate, closely followed by plate 2.
They can produce the full spectrum from hard hitting drums to very expansive and natural sounding guitars and vocals and all the way up to sparkling highs of cymbals.
My all time favourite tracks Hotel California and Comfortably Numb sound simply stunning on the Quattro’s, the dynamics of the recording really comes alive and I can nearly feel the music as well as hear it, the clarity these can maintain while punching deep bass at you is simply breathtaking. I have tried them with a variety of different music styles ranging from rock, electronica, dance music, classical and pop, and from what I can hear they seem to handle what they get thrown at without even breaking sweat. They may not be the most accurate or best suited for critical monitoring or provide the best absolute sound quality out there, but they are really, really good and so involving and fun to listen to. After all, does one go to a concert to dissect and analyse the sound, or to have fun and get involved in the music?
What do I think?
The sound they produce is nothing short of stunning plus it can be tailored to fit the listeners preferences, they have a generous accessory pack included, while design is subjective these really look nice, build quality and the metal housing deserves both thumbs up, they are light and very small and for my ears one of the most comfortable IEM’s I have ever tried.
The main drawback is the lack of availability in local shops, and a cleaning tool would have been handy to include.
Finally, I really can not praise these enough, for the asking price they are very, very good.
