I hate this cable. Battery is very small so you will hear it say "please charging" alot.
*their (possessive)
Love KZ stuff
The detachable cables are annoying because they always come out, and when they break it's usually cheaper to but a new pair of these than to buy a new cable
Other than that the sound quality is good, bit heavy
for bluetooth module… get TRN products
Agreed, the KZ bluetooth cables are junk. I've bought 4 of them, and 2 have died within a month of use. If you open them up, the soldering is very shoddy. Bought TRN wireless cable upgrades and they're more reliable and seem to have better range.
Look around in ali express quite pricey - TRN BT3 / BT10 slightly under US$20 while the BT20 US$30.
I've bought so many of these cheapo el-fako brands from $9 to $39 honestly they are all mostly shiite. Just wait for a pair of Bose to go on sale and you'll never look back. Also if $150 plus is over your budget check out Altec Lansing, they are literally the most under rated audio company (Their portable speakers and earphones/headphones are on par with bose with half the price)
OP can be misleading as the product itself is not wireless. Not sure about this Bluetooth module either
