The only issue I really have with this is the assumption of just "OK" sound. I've read reviews saying they sound identical to the OG AirPods, I've read reviews saying they're an improvement, I've read they are worse. Realistically, I couldn't even tell you if there was a consensus on what the AirPod Pros sounded like based on the more "professional" reviews. These are a midrange-focused signature which typically isn't everyone's cup of tea. The original AirPods were just "OK" and just passable for their sound quality. I stated this in my review above, but sonically, they are easily in the top 3 TWS IEMs that I own (the OG AirPods are easily bottom two, probably dead last). Just make sure you insert them as deep as you can get them and tip roll using something like the Sensaphonics Seal test (

At the same time, I might have a slight bias since I do prefer a more linear, more neutral, sound signature similar to the Etymotic or the HiFiMan RE0 as baselines. Both are regarded as very thin headphones because they are, but the bass depth is there on both with presence having difficulties (slight to major depending on who you ask). To be honest, they are the closest analog I have to describing the sound signature of the AirPod Pros. They are thin with just slightly better low-to-mid bass presence over my ER3SE having similar presence issues down in the sub-bass.
Another note, if anyone with the AirPod Pros want more bass, turn off the ANC and Transparency features. It creates a minor improvement in sub-bass presence which helps out the headphones quite a bit.
