Review on Anker Soundcore Liberty 2 Pro True Wireless Earbuds: Astria Coaxial Acoustic Architecture, In-Ear Studio Performance, 8-Hour Playtime, HearID EQ, Wireless Charging by Nguyn Th Bnh (Nht Ph ᠌

At first, I was one of the few customers who was dissatisfied with their purchase of these headphones. To which recording studio do I need to listen to hear the reference sound that everyone else seems to hear? I was unhappy with the purchase and at a loss as to what to do with them when I heard the tin rattle. The mids were horrible and no amount of equalization adjustments helped. Nonetheless, there was little need for concern because the majority of reviews were still good. I looked for customer reviews online and eventually found one on irecommend. A man, outraged at the price tag for such supposedly high-quality goods, sought to find out how long they could play at full volume before dying. It took around 7 hours, and most crucially, the experiment had the unintended consequence of altering the sound he heard afterwards. Warmed headphones, to use the jargon. My ignorance of the concept of "warming up the headphones" led me to seek out guidance on the topic online before attempting the process for myself. In order to properly warm up in-ear headphones, it is recommended to listen to specialized white noise for 12 hours at a volume of 75%. Overnight, I listened to a track that had this noise. And then the next day, the mids were totally different! The sound drastically altered; it looked to be refined, and new levels of detail were audible. It's worth noting that some have argued that warming up is pointless when it comes to reinforcing headphones, but the conclusion is clear any way. For me, warming up beforehand was crucial. If you find yourself in a similar predicament, rather than immediately becoming angry and running to return the headphones, consider warming them up first.
