At full price, however, even I had to wince. As good as they are, I don’t personally think they offer a big enough leap over their predecessors to be good value at their normal price. However, with Amazon Singapore offering a SG$120 discount for Prime Day, that's a big enough saving to change my mind.

Personally, I wouldn't spend less than this on Prime Day on wireless headphones. The Sony WH-CH520 are a brilliant budget buy, and we haven't heard a rival pair that's as competitive at this level. They produce a balanced, engaging sound and boast a whopping 50 hours of battery life. A no-brainer for the money. Five stars
