As a conclusion, the music reproduction, high sound fidelity, and audio performance are almost flawless. The 11mm drivers provide an exceptional soundstage for these small earphones. The bass is deep, clear, rich, and powerful, never distorting even at maximum volume. It has noticeable power even at low voice intensity. It guarantees satisfaction for bassheads. In R&B and hip-hop songs with particularly heavy, abundant bass in their composition (a few isolated cases), there is a slight masking effect on the mid frequencies. The lows are strong and cover a wide range of mids in these cases. The vocals from the Liberty 2 Pro are always lively, crystal clear, and dynamic, just like the high frequencies. The mid frequencies are full and detailed. They do not forgive music or sounds of inferior quality, such as poor recordings from YouTube or similar sources.
The construction is durable, made with high-quality materials. It comes with 6+1 pairs of different-sized ear tips and 2+1 pairs of wings that secure the earphones in the ear canal. The charging case also functions as a wireless charger. The passive noise isolation, provided by the ear tips, is quite good. The autonomy is 5 hours and 10-15 minutes at maximum volume with uninterrupted playback, with the right earphone running out of battery slightly earlier than the left one. The case can fully charge them 3 times, but almost never 4 times.
There are dual microphones on each earphone, which may cause slight interruptions in the sound when speaking. You need to speak slightly louder because the microphones do not pick up certain frequencies and below. Generally, this is not a problem.
The Bluetooth connection is stable, reaching almost 15 meters in a straight line without obstacles. They connect to one device at a time. They do not fall out of the ears unless you are doing capoeira training. They are unaffected by sweat or walking in normal rain. When playing audio from videos, movies, or video games, they have an immediate response and do not delay the sound.
You can use a single earphone, either left or right. After approximately 4-4.5 hours, they become uncomfortable and need to be taken out for 2-3 minutes to rest the ears. This is not due to weight but rather the fit. They may appear somewhat bulky on a refined, normal-sized head, but they fit perfectly on a watermelon-shaped head like mine. Sometimes, I detect white noise at low volume. It is not bothersome but becomes noticeable. There is also the Soundcore app, where the sound reaches a whole new level. It offers 34 sound styles, including custom, professional, and personalized earphone options. It also includes the ability to change the energy (command) from the default setting, which is controlled by the single button on each earphone. Software upgrades are also available.
The Liberty 2 Pro may be a bit pricey, but they are not too expensive considering the quality they offer. They are paradise for music, movies, etc., but they could be better for calls and communication.
