What I like most about the earbud is how tiny the thing is, and easily placed in the pocket. The other big plus is that it delivers crisps sound when on call without the normal humming and repeated echoes heard when talking with someone and with the combination of LG's app Tone for sound setting and such, using the earbud while driving, I can activate the ambient sound so I can easily listen to ongoing traffic, because the earpiece blocks the surrounding noise, and you don't want that when driving, but bear in mind to set the ambient setting to low because it catches all the surrounding sound and you don't want to have anxiety attacks while driving because everything sounds so near to you. But feel free to use max level ambient sound mode to be a super ninja, in case you want to eavesdrop on someone.
For the enjoyment of music, using the apps is a must, and I prefer using the Bass Boost as it sounds like listening to music in a concert. And Treble Boost when listening to a speech or a talk because of the clarity of what that person's speech.
For the best part, I'm using it to play mobile online games, and with the equalizer set to Immersive, any footsteps, gunshots, or movement will easily be detected,
The volume increases slowly when pressed, so you don't have a major scare when accidentally overpressed.
As for the UV nano cleaning, as a person with sensitive skin, this is a big help for me, because, after some considerable amount of time using a normal bud, my ear canal would start to itch and it begins to form rashes, but with the UV nano, it seems that I can wear the earbud all day long without any discomfort.
For the cons, I have trouble disconnecting it from the phone when placed in the earbud charger case, it has to be aligned perfectly or else the sound will come from the bud instead of the phone, and when browsing or opening apps in the phone, it will cancel the ambient sound mode for a second.
To sum it up, the quality versus price, it is on par with most of the middle top tier expensive earbuds in the market with a fraction of the price, and it's a must-get item if you appreciate great sound music, hassle-free gadget, and simplicity at it best.
