Hi there! If you're looking for a budget-friendly Bluetooth earphone with a good microphone that will allow your conversation partner to hear you loud and clear, I have a couple of recommendations for you:
1. JBL T110BT: This is an affordable option that provides decent sound quality and has a built-in microphone. It fits comfortably in the ears and has good noise isolation, allowing your voice to come through clearly. The battery life is also quite impressive, offering around 6 hours of music playback.
2. Anker Soundcore Life P2: This is another great option that offers excellent value for money. It features CVC 8.0 noise reduction technology, which helps ensure clear call quality by reducing background noise. The earbuds are also comfortable to wear for extended periods, and the battery life is solid, providing up to 7 hours of playback on a single charge.
3. SoundPEATS TrueAir2: These earbuds are known for their affordability and good call quality. They utilize dual microphones for noise reduction, which helps to improve the clarity of your voice during phone calls. The battery life is also impressive, with up to 5 hours of playback time, and the charging case provides multiple additional charges.
Remember, even though these options are budget-friendly, they still offer decent performance and should meet your needs as spare earphones with a good microphone.
