Reasons Why You Should Buy Them

  • JBL Reflect Flow are a well-sounding pair of Bluetooth in-ear sport headphones with a big and punchy bass, a decent mid-range, and a tight, crisp high-range
  • Fully waterproof due to IPX7-rated, JBL Reflect Flow earbuds can be fully submerged in water for up to 30 minutes and 1 meter
  • Three different eartips and three optional secure-fit earfins help you find a perfect fit
  • Built-in controls and mic to answer calls, skip tracks, music play/pause, select Ambient Aware mode and connect with Siri or Google Assistant
  • Ambient Aware mode is a small but practical feature if you need to keep an ear open for external announcements without taking off your headphones
  • “TalkThru” temporarily silences the music for 5 seconds, which is good for intermittent greetings, but not for conversations
  • The JBL Reflect Flow True Wireless come in a variety of colors - Black, Blue, Green and Teal, a definitive accessory for fashion-conscious fitness fans
  • Up to 10 hours of battery life on a single charge and 20 hours of extra power with the charging case
  • Status LED battery indicators on the back of the charging case to check the amount of juice left
  • Quick charge technology of JBL Reflect Flow Sport offers 1 hour of playback with only 10 minutes of charging time

Reasons Why You Should Avoid Them

  • JBL True wireless earbuds still come with obsolete micro USB charging port instead of the new USB Type-C
  • If you like subtle sound, JBL Reflect Flow True Wireless are not for you as these are tuned for bass heavy music
  • The JBL Reflect Flow Wireless Sport In-Ear Headphones sound great, as long as you get a good fit, otherwise they sound thinner than they should
  • There is no JBL Reflect Flow app that can help you control your headphones for a more personalized listening experience, like some of competitors' new truly wireless headphones
  • JBL Reflect Flow True Wireless Sport Headphones has no on-board buttons for volume control or skip tracks, you need to take your smartphone out for this
  • Microphones catch too much outside sounds, making it difficult for the person on the other end of the call to hear you clearly
  • JBL Under Armor True Wireless Flash is an almost similar pair of in-ear Bluetooth headphones, but with a more balanced sound signature
  • The shape of the JBL REFLECT FLOW True wireless sport headphones makes it a little difficult to pull them out of the charging case
  • According to JBL Reflect Flow Instructions, there is no support for superior Bluetooth codec like aptX, aptX LL and aptX HD (only AAC and SBC codec support) for better audio quality


  • In-ear headphones with ergonomic silicone tips and patented Freebit amplifiers for a comfortable fit
  • With Bluetooth 5.0, you can discover the freedom of a listening experience without cables or wires
  • JBL Reflect Flow supports AAC and SBC Bluetooth codec
  • The 5.8mm driver with JBL Signature Sound delivers bright, powerful audio for running, daily commutes, gym sessions and more
  • On-board controls allow you to manage music, take calls, or access your voice assistant
  • Ambient Aware mode let you stay aware of the world around you
  • TalkThru let you have a conversation without taking out the earphones
  • IPX7 waterproof rating keeps the earbuds safe from sweat, rain and splashes
  • 10-hour battery life plus extra 20-hours in the charging case
  • Extra one hour of listening time with a quick 10-minute charge
