Review on TREBLAB X5 - High-End Bluetooth 5.0 Earbuds: True HD Sound, Deep Bass, Best Sports Running Truly Wireless Headphones with Noise Cancelling Mic, Waterproof IPX4 (Renewed) by Nancy Levisay

Bad battery life, after about a year the battery life went from about 4.5 hours to about 1 hour. I contacted Treblab and they tried to tell me this was normal. They claimed that battery life would drop to 80% after a year. From 4.5 hours to 1 hour more like 25% of the original. Unnecessary batteries in them rendered these headphones almost useless after a year. Also, the microphone doesn't work well on them. I tested it on my phone with other wireless headphones using the same phone and my calls from the Treblab X5 were difficult to understand. The case also cracked without the impact of a fall or anything like that. I just opened the lid and it cracked. Unfortunately, this is where the main problems lie, because the sound is excellent.
