JBL Wave Buds Wireless Earbuds I received these as a new gift, but I have never used them. I opened the box to check the contents. There is no receipt, so there is no warranty. Please refer to the description below♪ Comfortably fits even small ears with the series' smallest and lightest compact body. The internal structure has been significantly revised, such as changing the button operation on the earphone body from the previous model "JBL WAVE100TWS" to touch operation. Without sacrificing functionality or sound, the size of the earphone body has been downsized by about 20%, making it a model that can be worn without a feeling of pressure even for those with small ears. Of course, there is no compromise on sound quality, even though it is an entry model. Equipped with an 8mm dynamic driver, you can enjoy the rich, clear, and powerful sound that JBL boasts, making it the perfect product for your debut as a truly wireless earphone. The unique design of the lidless charging case, which was adopted from the previous model, reduces the effort of opening the lid when using it, making it easier to take out the earphone body. Furthermore, the case itself is waterproof (IPX2), which is the first for JBL in Japan. Combined with the earphone body, which has been upgraded to IP54 with the addition of dustproof function, you can use it with confidence in a wider range of scenes, such as outdoors and sports. In addition, the earphone body can play for about 8 hours, and the charging case can charge for 24 hours. It achieves a long wireless playback time of up to about 32 hours. Furthermore, it supports JBL's dedicated app "JBL Headphones". You can customize the earphones to your liking by setting the equalizer and adjusting the voice aware.
