When pairing the Champion earbuds, you have to remove the earbuds from the charging case in order to trigger automatic bluetooth pairing. The status leds on the Champion earbuds blink red every 10 seconds during audio playback. The Bluetooth 5.0 chip does not support advanced codecs; hence not aptX or AAC support.
Once both earbuds are paired, you can seamlessly alternate between using two or one earbud in the charging case without audio pausing or bluetooth disconnecting, which can happen with some true wireless. That said, there is a 2 second re-connection delay when taking the earbuds from the charging case, which is not a lot since some true wireless have a re-connection delay up to 7 seconds. This said, some true wireless re-connect instantaneously without delay.
Audio-wise, there is good volume output (98dB), as well as vocals and instruments sound punchy and clear, while the bass is present, although a bit more subdued than expected compared to the midrange and treble. This could be due to the small driver size (6mm) or thin silicone tips, which are made of recycled silicone material. Using foam ear tips does help to improve the bass but foam tips do bulk up the earbuds, preventing you from fitting them back in the charging case.
Fit is comfortable and secure on the ears, thanks to the rubberized trim running across the body of the earbud. You can do exercise with them, although the Champion earbuds are only IPX4 rated. The nozzles have aluminium mesh tips and they are angled so, they insert naturally inside the ear canal. 
Just like all House of Marley products, the Champion earbuds come inside eco-friendly packaging without any plastic wrapping or plastic coated wire ties. There is a short charging cable made of stiff fabric material, as well as an extra pair of ear tips included but no different sizes.You can buy the House of Marley Champion earbuds on amazon.
