Lenovo HE05X Bluetooth 5.0 Waterproof Wireless HIFI Sound Magnetic Neckband Sports Headphones

•  BT Version: 5.0: This indicates a modern Bluetooth standard. Bluetooth 5.0 offers greater range, faster data transfer speeds, and improved power efficiency compared to older versions like 4.2. While the version itself doesn’t guarantee better audio quality, it does provide a more stable and reliable connection, which can help support higher-quality audio codecs.
•  Play time: Max. 7h: This is the maximum continuous listening time on a full charge. A 7-hour playtime is reasonable for a pair of wireless headphones, suitable for daily commutes, workouts, or extended listening sessions.
•  Standby time: Max. 120h: This is the amount of time the device can remain powered on and connected to a source (like your phone) without playing audio before the battery runs out. A standby time of 120 hours (5 days) means you won’t have to constantly recharge them if they’re not in use.
•  The loudspeaker diameter: 10mm: This refers to the size of the driver inside the earpiece. A 10mm driver is a common size for in-ear headphones and earbuds, and is capable of producing strong bass and clear sound for most listeners.
•  Frequency range: 20-20kHz: This is the audible range for most humans. A frequency range of 20Hz to 20,000Hz (20kHz) is a standard specification for headphones, indicating that they can reproduce the full spectrum of sounds from deep bass notes (20Hz) to high-pitched treble (20kHz).
•  The connection distance: 10M (barrier free): This means the headphones can maintain a stable connection to your device up to 10 meters (about 33 feet) away, as long as there are no physical obstacles like walls or doors blocking the signal.
•  Sensitivity: 108dB±3dB: This measures how loud the headphones can get with a given power input. A sensitivity of 108 decibels (dB) is considered quite high, meaning these headphones are efficient and can produce a loud volume without needing a lot of power.
