Build, fit and packaging 

The earbuds come in a nice, cardboard box. The box has a nice opening and closing action – similar to watch cases. There is a tiny manual in Chinese. We are also provided with 7 pairs of donut foams an 2 pairs of regular foams and the quality it good as well. There is an interesting, plastic shirt/collar clip too, that I haven’t seen before (Need to explore on how to use them).

The buds themselves are quite interesting – nice metal housing with an open faceplate that seems to give a exposed-driver type look. The buds have MMCX connectors, but I was unable to remove the cable that they came with. Even when my pulling force was good enough to leave some nail marks on the connectors, I was just unable to disconnect the cable. The standard cable looks industrial for a premium looking earbud, especially due to the paint texture on them. A simple, black colored cable would have looked better. The cable has plastic Y-splitter and cable slider; the cable slider works quite well.

The 3.5mm jack is L-shaped and a heavy one too. Looks good though!

The housing is smaller than the MX500 shell that is normally seen on earbuds and they are quite comfortable. The can be worn cable down or cable over ears (as intended by the manufacturer). I like wearing them cable down as I get a better seal that way and the adjustments for fit are more easier.

Foam Matching 

Foams are critical to get the right sound out of any earbuds and choice of foam have a greater impact on the sound signature. Foams help with seal and can be used to customize the warmth and bass on offer.

The TI7 comes fitted with donut foams, which I feel offer the best balance for these buds.

Without foams – Due to their smaller size, they don’t give a good seal, which impact bass quantity.

Donut foams – A good balance across the spectrum – adds the right amount of warmth.

Full foams – Same as donuts, but can be a bit miserly on the details of the highs. The donut still has some exposed vents which aid the highs.

Thin foams – Did not try these.

Conclusion
The OurArt TI7 is a great attempt at offering good technical performance at an affordable price. While, its analogue, mid-centric sound signature may not suit all genres of music, they can still get a smile on your face for most chartbusters that people usually listen to.

These are the perfect pair of buds for work and sleep, due to the comfort and non-fatiguing sound they offer; after all you need good hearing to listen more.
