Customer Reviews for JBL Reflect Flow Pro Waterproof True Wireless Noise Canceling Active Sport Earbuds
1. My earbuds have an issue with position and functionality. The bug with functionality is that music can stop when you just turn your head left/right or go fast. When I disabled all functionality in the Android "JBL Headphones" application I faced another bug(( If you turn left/write your head you will hear "device connected" words even if it was connected and plays music.
2. My brother left earbud just stopped charging. The right earbud works perfectly without any bugs.
The sound quality and battery life are excellent, but due to low reliability, I couldn't recommend them for purchase.
As far as sound quality these are wonderful. For studying and relaxing at home? Great! But these are literally marketed as being great for workouts and they are NOT.
1) The earbuds & app randomly reset the settings back to factory default state. I use the app to set them up so I have volume control by tapping. Every so often, this is lost - I usually discover it a couple miles in.
2) I design electronics for a living. These devices may have passed an IP test, but they are not well designed. One of earbuds got earwax on it which plugged / covered the speaker. It is impossible to clean out, and the volume is extremely low and muffled. Sound quality is terrible and I need to turn volume to max. just to hear anything. With volume at max. I constantly get messages from my phone saying I am damaging my hearing .... despite barely hearing the sound.
3) The other ear bud will malfunction and completely turn off when I get particularly sweaty - which is a common event when running in Texas. It will not work again until it has hours to dry out.
Overall these were too expensive to work properly for such a short time. With other products I've been able to enjoy them until the battery end of life was reached.
If you are okay with constant faffing about with apps and you are okay with carrying the case about wherever you go as well as constant messaging to connect with Google voice commands then you should be fine with these headphones.
I have used JBL products for years and my previous JBL Free x never missed a beat until they went through a hot wash (and dry) - and even then they worked intermittently. The thing that made them good was the ability to turn them on... and off... with a button. As crazy as it sounds they had an on and off switch, whereas the flow pro will time out after 10-15 mins and become just two useless bits of plastic. In addition to the above, I have had constant connection issues such low fi sounding music following a call and which then requires to unpair Bluetooth and repair - only to find that it will no longer re pair without the case. This happened the first time on a long walk in the middle of nowhere with the case left in the car. Because why would you expect something that has individual batteries to have the ability to be witched on and off - that's just something of the past surely. I've contacted JBL customer services who has essentially said - it's fine - that's what they are supposed to do. I think my next headphones or speaker will be from a different company. It was good while it lasted.
