OpenRock S2 Open-Ear Sports Earbuds are their latest on offer and packed with features as expected and we have been testing these out the last while and it is time to talk about them if you are in the market for new Open- Ear sports earbuds these might be for you.
Presented nicely as always you will find all you need in the box and the case itself is quite cool with a pebble type matt finish means it is not a case that will slip out of your hand like some can.
The earbuds themselves are quite cool with not touch based options but they have a button at each end that works perfectly each time allowing you to get the command you want rather than unwanted ones you would get with gesture based earbuds.
The fit is secure and these will not fall out they are also light and robust look well and clean and not cumbersome looking, in fact after some time wearing them you will forget they are there.
There is all the features you would expect to find here and with their app you have some new options you can play/pause,skip/reverse access your voice assistant and volume control you can also manage calls and all actions tried and tested worked well each time.
Battery life is also impressive here with up to 32 hours on a single charge and there is also fast charging which 5 mins charging giving you up to 8 hours which is impressive. Battery longevity will of course vary by user and their settings as usual. Users can also set safe volume limits and over-time reminders via the APP as we demo in the video review below.
Sound is excellent here with the 12mm drivers and 30w output inside despite no ANC which means you can hear your surroundings but the type of user these are aimed at it is not a bad thing, in a quite environment you would be the full benefit of near in er earbuds it must be said and overall the sound is excellent for open-ear earbuds you also have access to the app seen below for more options including find your buds and much more.
Overall for the price here and being ope-ear earbuds they are easy to recommend and pack a punch with audio and do not sound tinny maxed out or have any latency issues, calls where also good here with their 4 mic AI noise cancellation and to top it off you have dual device connectivity which today is an important feature for those who work from phones and laptops together.
