In terms of headphone battery life as a significant factor in the purchase decision, it depends on what you want to use the headphones for and potentially how often you will be able to recharge them. The Samsung Gear IconX Truly Wireless are a better headset overall when compared to the JBL Free Truly Wireless 2018. I use them frequently while working around the house and yard, but my ears are small so finding something comfortable is challenging.

You can use the earbuds out of the box, but the JBL Headphones app (available for iPhone and Android) adds additional features.Also, the response throughout the range is very well-balanced and virtually flat, but it is consistently over our neutral target by about 1. The significant portion of their leakage is spread over a very narrow range in the treble range, around 2KHz.

The JBL Free Truly Wireless 2018 are slightly better truly wireless headphones than the Apple AirPods (1st generation) Truly Wireless when they have a stable connection. One of the main advantages of these headphones compared to over-the-head ones is their stackability and easy portability. It is important to remember that high listening volume can consume more energy from connected devices. You will have to pull out your phone whenever you want to lower or increase the volume of your audio, which is slightly disappointing. When it comes to frequency range, a wider range will allow more detail to be heard during your listening session.

If you want a decent sounding and stable in-ear with a wired connection, we would suggest the Mee Audio M6 PRO or the 1More Triple Driver In-Ear. Like most truly wireless headphones, these are small in-ear buds that will fit in almost any pocket. Non-wired headphones don't include additional components such as wires, therefore they tend to be more compact. The GD graph also shows that the group delay response never crosses the audibility threshold, suggesting a tight bass and a transparent treble reproduction.
