The SIVGA SO1 Open-ear True Wireless Sports Earphones are a simple to use pair of earphones that have a rather large case but the colour is nice here in my opinion, the case is on the large side and might be an issue for some but overall the package looks well and is well presented and the case has got wireless charging.

The fit is very secure and will not fall out of your ears and with an IPX4 rating ideal for those on the go like cycling jogging and even the gym after my testing they did no budge, I have took up mountain biking recently and they worked a treat and I can also hear what is going on around me which is important.

The sound is surprisingly good coming from these with directional audio and better than I expected which is good to see, there was no distortion or tinny sound when maxed out and highs lows and mids sounded fine with a nice balanced level all round with some bass in there and all genres came across well so I was happy with how they sounded and they don’t sound cheap. No lag latency was noted during my testing either.

S01 is equipped with military technology chips and scientific software algorithms to achieve directional audio transmission. It is paired with a special 16.2mm biological composite diaphragm speaker and a special sound direction design, bringing a music experience that surpasses most current TWS earphones

There is one button each side and act as an MFB ( multi function button) and these work well they have all the control required for your needs and all the controls are there which is calls skip and reverse tracks voice assistant and of course volume control and they work all the time every time with no issues at all.

Battery life is decent enough and the case gives you wireless charging which is handy but on the larger size and not an issue for me but overall the sound quality call quality and so on was quite good for the asking price and something you should look at if you are in the market for a new pair of sports earphones.
