AirPods with Wireless Charging Case retails for S$299 and AirPods with Charging Case retails for S$239. So to be able to charge your AirPods case wirelessly via Qi, it cost an extra S$60.
I managed to get my AirPods with Wireless Charging Case during Lazada‘s mid-year festival flash sale for just S$239 (there are only 200 units available). With a S$20 Lazada voucher (minimum spend of S$180) and S$10 HSBC credit card discount, I only paid S$209 for it, and that means I have gotten a S$99 discount. It is a super good deal.
A single charge gives you 5 hours of listening time or 3 hours of talk time. A quick 15 minutes charge will provide you with 3 hours of listening time. Coupled with the charging case, you will get a total of 24 hours of listening time.
AirPods (2019) design, dimension (16.5 x 18.0 x 40.5 mm), and weight (4 g) are precisely the same as the previous generation, AirPods (2016).
For the standard Charging Case, there is no difference in design, dimensions (44.3 x 21.3 x 53.5 mm), and weight (38 g) as well.
For the Wireless Charging Case, the dimensions remain the same while there is a 2g increase in the weight (38 g vs. 40 g).
The only visual difference between both cases is the additional charging indicator found in front of the Wireless Charging Case.
Internally, it is a considerable improvement due to the new H1 chip being used instead of W1. H1 chip allows the AirPods (2019) to pair faster, more stable connection, 30% lower latency, and a 50% increase in battery life (due to it being more efficient).
Despite the new H1 chip being used, there is no difference in audio quality between both generations of AirPods.
