I bought this because im a frequent music listener i like to hear the good thump and those sweet 808's so when the specs said capable of 20hz i just wanted to give them a try and they work. You're getting what you came for but the problem here is that there is leakage from the ear. the design is not meant to be in the ear and that makes sound come right in. when im running or in my car all i can hear is the road and my own steps. It also muffles the sound and the bass is unhearable not to mention the bass is not what it says. It's actully roughly about 34-36hz and up. none the less decent headphones for its price.

JBL Tune205BT - Nice bluetooth speaker. I would suggest one improvement. The length of the flat wire which goes around the neck should be increased by 20-25mm. Present length is 280mm. I would suggest increasing this to 305mm. During the use I feel that the mic goes inside the shirt collar and the listener on the other side has to struggle for hearing. I have been using this product for around 2 weeks. Rest sound quality is good as expected from JBL. Bass level could be better but with this price range it is OK. I would insist the engineering / R&D team to relook at the length of flat wire which goes around the neck.

The product started behaving weirdly just fall short of 1 yr and now there is no one to help me and my money is a waste. This is unacceptable for a high voiced brand. There should have been better compensation for bad product performance. I generally used it while running and exercise and zoom meetings. In all 3 it failed. The mic doesn't sync well with zoom meetings and earphone pops out and while exercise. And finally, it is not working after 1yr 10 days. Kudos to the exact warranty period.
