Thinksound has been kind enough to give me their ts03 for review, and priced at 120USD, they are certainly quite good. With an impedance of 16 ohms, and 99dB/mW sensitivity, and a one button remote, these are clearly designed for use with a phone, and have been powered by my iPhone 6s for this review.

Included in the packaging are a whopping five sizes of silicone tips, a shirt clip, a small canvas carry pouch, and a little Altoids tin-like case. The plethora of tip sizes ensures these will fit nearly any ears, with both some of the smallest and largest stock tips I have encountered.

The earphones themselves are pretty well built, with a very sturdy wood and metal housing. The cable is non-removable, which is a bit frustrating. This cable does fortunately feel mostly pretty sturdy, though its connection to the housings feels a little bit flimsy, and I would have liked a bit more strain relief at the y-split. All in all though, these feel like they will last. I certainly would have liked a removable cable on these, especially at this price point.

Comfort on these is very good. With a small, roughly cylindrical housing, it is hard to go wrong. These are designed to be worn cable straight down, but they can also be worn just as easily with the cable over the ear. One caveat though, is that when inserting them, you can hear a crinkling sound coming from the earphones, which may be driver flex, though I can’t say for certain.

These sound quite good, with a sound that is overall slightly warm and bassy, and sounds slightly dulled, and very relaxing. The bass sounds quite clean and controlled, never sounding bloated or flabby. Bass notes thump very nicely, providing plenty of impact without taking away from the rest of the track. These can present bass as the central component when needed though. The midrange sounds very clear and pleasant, though not quite as crisp and clean as many IEMs at this price. The lower midrange is clearly elevated relative to the upper midrange, which combined with their slight dullness gives these a very relaxing presentation. This is not to say the midrange is bad, it is quite good, but it does not quite have the detail of some other units at this price, but it makes up for that with their very pleasant presentation. The treble also shares this slightly dulled characteristic, though less so than the midrange. The treble is very smooth, without any obnoxious peaks I can hear. While it does sound slightly veiled, the treble certainly keeps up, providing just enough detail and sparkle to keep it from becoming boring, but allowing this IEM to keep its very relaxing sound. Soundstage on these is surprisingly wide, which also adds to their relaxing character. Imaging is nothing spectacular, but it certainly keeps up.

All in all, these are great IEM. With a very relaxing, spacious sound, if you own a pair of these, or buy one, do yourself a favor and listen to Yosi Horikawa through these. That sort of calming music is what I feel these do best.

Now, at 120USD, what are these competing against? Two major competitors to these are the TFZ King and the RHA MA750. I no longer have either on hand, so I cannot say much of substance, but the King is brighter overall, so is less of a direct competitor. The MA750 however, is tonally closer. Unfortunately, I cannot AB between the two directly to give a good comparison. A third potential competitor would be the new MEE Pinnacle P2, which I have not heard yet, but I will review, and I will compare the two in my review of those.
