TrueEngine III SE takes everything TrueEngine SE does well and makes it better. Sound quality sounds just as good and if not even better than the TrueEngine SE, retaining that strong bass that the SE was known for. The design has been improved to be slightly thinner and sleeker-looking, so it doesn't protrude out of your ears as much as the SE did. The controls are fully touch, doing away with the old buttons that the SE had. And they are now much more responsive without having to constantly press the earphone into your ear to change tracks or play/pause. The charging case also looks sleeker in my opinion, finally utilising USB-C instead of the old micro USB. In addition, they even include a pair of COMPLY premium ear tips out of the box! Which come with memory foam and noise isolation features. If you liked the SE you will love this, it is truly an upgraded and improved version. And if you've never owned the SE series or are just looking for a solid pair of in-ear earphones from Soundpeats, look no further!
