Input:
I just received the J3s a couple of days ago from Amazon. I previously had a pair of JLabs J2s for 2 years and loved them! Unfortunately, the 3.5MM plug finally gave up the ghost and broke. After spending many hours of reviewing J3 and the new J5s on Amazon I came to the conclusion to go with the J3s. The main reason I chose the J3s over the J5s was price. It also helped that the J3s came with a case to put them in. I feel I would have been more inclined to purchase the J5s for the extra $8 if they had also come with the case. I also noticed in my research that the housing and driver size was exactly the same between the J3 and J5s. The best part of the J3s, now that I have broken them in, is the frequency spectrum they cover. Some reviews talk about the J3s having too much treble and I agree with that when they come directly out of the factory packaging. However, if you go to JLabaudio.com and use their burn-in tool for 8 hours, the sound quality and frequency response has much more depth. I would say that having to do the burn-in is the only drawback for these ear buds (I would give 4.5 if I could since the burn-in is not convenient if you want to instantly use the ear buds). For $20 the burn-in should really already be done at the factory. Overall as the review title states, the J3s are an excellent upgrade to the J2s! Keep up the good work JLabs!
