AVIOT - TE-J2

Just for the sole purpose of sound quality,  1. Noble fokus rex5 2. Devialet gemini 2 3. B&O beoplay eleven 4. Aviot TE-ZX1 Above 4 are on the very expensive side.  Cheaper (from different seller cheap price with promotions  + discounts), around 300, is noble fokus amadeus. It has better battery than expensive rex5. Technics az100, if you don't use anc, the battey will last you more than 8 hr s for sure. It is currently best earbuds, all around for sound battery, features Aviot TE-J2 is also better (cheaper also) , just don't use anc, use it for the sound that you want.  Above earbuds are like fully cooked food. If you want like a half cooked food, like 3 hr of battery life, lots of small little inconsistent things. But respond really well to eq customization, relatively lot cheaper than above earbuds ( like 1/3rd of the price of az100 or te-j2 ), that earbuds would be soundpeats h3. I wouldn't recommend it at all.  For your budget, az100, fokus amadeus, te-j2 ; will definitely serve you well.
