First of all, they sound great. They have heavy bass, good highs, lows, and mid. The audio is extremely crisp and I could honestly compare them to my Sennheiser Momentum In ear earphones. They have amazing passive noise cancelling with the default earbuds being able to fit in my ear perfectly and form a great seal. They also provide a wide variety of earbuds if you have a different ear size. It helps with my commutes on the train, as it drowns out the talking of other passengers.
The earbuds are also fully wireless which is also extremely convenient, as I don't have to worry about the cables tangling. They are very small, discrete and lightweight, making it perfect, as I can wear the earphones for a long duration of time without pain or discomfort. They aren't as bulky as other wireless earphones and are pretty flat with my ear. The case is also great, as it stores the earphones away while not in use and also charges them for many hours. The seamless pairing is also amazing, as I just had to pair it up once and from that point on, the Truedots would just instantly connect whenever I pulled the out of the case, which is a delight!
The final thing is the price. For under $40, these earphones are amazing! You can't find anything else like them. They connect seamlessly, they sound great, they're lightweight. Other earphones can drive you upwards of $100, but these are honestly great value. I recommend these earphones to anyone. This will make the perfect gift.
