EARDECO 180 Hour Endurance Bluetooth Headphone Bass Wireless Headphones with Mic Stereo Neckband Earphones Sport Headset TF Card

Authenticity of 180 hours of battery life Typical: The advertised range usually refers to a total of “single charge + charging compartment refill” or lab data at very low volume. Actual estimate: Headphones last about 8-12 hours on a single charge (medium volume + noise cancellation off). Sound quality and hardware Bass performance: relies on more than 12mm moving coil unit + rear chamber tuning, but the neck-mounted structure bass is naturally weaker than the head-mounted. Microphone quality: CVC8.0 noise reduction technology can meet the demand for calls, but the effect of anti-wind noise during sports is doubtful. TF card support: rare feature, may be limited to offline playback of MP3 files (need to confirm whether to support lossless format).
