My favorites of 2019:
TinAudio T2
This is the earphone that put TinAudio (TinHifi) on the map. If you can get a good fit with its fiddly shell design, this dynamic driver earphone is an incredible value. It is versatile, and can be worn up or down. Some find it a little light on sub bass, but covering the bass vent with a piece of 3M Micropore tape will provide a low end boost. TinAudio followed up the T2 with the T2 Pro and T3, but many feel the original T2 is the superior model of the 3.
Blon BL-03
The budget BL-03 has been riding a hype train for the last few months, but I feel the hype is well deserved. A carbon-nanotube dynamic earphone, it was tuned by the same person responsible for the impressive Tanchjim Oxygen. It can also be worn up or down, but the latter will require a 3rd party 2-pin cable with a straight end and no ear hooks.
Audiosense T800
This is in the mid-fi range ($300), so it may be out of some people’s budget. However, the price is worth every penny, and has been cited as an ‘end-game IEM’ by more than 1 individual (myself included). The T800 packs 8 Knowles BA drivers per side, a solid resin shell, user-replaceable Knowles tuning dampers, and a generous assortment of accessories. The T800’s secret is its vented BA woofer, which provides enough sub bass that will have you doing a double take wondering if the T800 secretly houses a dynamic driver.
Toneking NineTail
Don’t let its odd shell fool you. This is an excellent earphone. It’s ridiculously comfortable, and has front and rear tuning filters for a total of 9 possible tuning combinations. Just keep an eye on the filters though, as some have lost them by not screwing them on tight enough. If you’re looking for a step up from the typical >$50 budget earphones, the NineTail is it.
