Purchased this OpenFit because I want to be able to enjoy my music while running, and at the same time also want to enjoy the sounds of nature around me. Yes Tech House and sounds of forest and heath go together beautifully. For that reason, over-ear headphones also fell off. I also have in-ear earphones, but I have those ears where when the ear canal is closed, my footsteps / cadence resonate extra loudly in my ear.
The sound quality is top notch. However, don't expect the deep fat bass of closed earcups. That is simply not possible with this design. You are not cut off from your ambient noise. There are a few equalizer presets with bass boost, among other things, and you can create your own profiles. The sound is also fine for conversations. My interlocutors did not realize that I was conducting the conversation through the earphones.
It is all beautifully designed, the earphones themselves and also the small storage box that also serves as a charger. It is so small that you can easily take it with you everywhere. Pairing via Bluetooth (the first time) is also only possible if the earphones are in that box. I use them together with my smartphone and my Garmin running watch. In both cases I listen via my Spotify account.
Switching between listening via the smartphone and my sports watch is not always smooth. The earphones must then be returned to the box for Bluetooth pairing. That's because this OpenFit doesn't support multi-point pairing. That is also a small downside, which I hope can be solved with a firmware upgrade.
Another thing to pay attention to is that you place the earphones properly in the box. Via an LED you will receive confirmation of the correct placement of your left and right earpiece every time. It can hardly go wrong, but I have already had a time where that went wrong and my left earpiece only had 20% juice and the right earpiece was fully charged. During the long run, the left earpiece finally stopped working after a number of warning tones. Fortunately, the judge proceeded happily.
I find them ideal for running. When cycling you will get more wind noise anyway, but that is inherent to the design and the higher speed. The simple solution is to turn the volume up a bit. I never get above 60% myself and can still hear everything well.
You operate the earbuds by tapping the speakers. You can choose between a number of presets. Stop/Start, next, previous, volume up, volume down. The limitation is that you can only choose a maximum of 4 out of 5. My settings are Stop/Start, Next, Previous. I then do volume control via the smartphone or my sports watch. For example, in practice, a long hold to select the previous one doesn't work well. By the time the earpiece responds, it will have jumped back to the beginning of the song, start playing, and the next long-hold will not result in the previous-previous, but in the replay of the current song. It is therefore important to choose the presets that work for you.
Apart from the two minors (not always handy Bluetooth connection and limited useful choice in presets) this is an absolute must in my opinion. Don't run a single run without my earphones.
