They give excellent battery, which offers up to 130 hours of playtime. With the 2600mAh charging case included, so they can also be a power bank for charging your mobile. The build quality is good and far better than other wireless earbuds for this price tag. The Duet 50 Pro is one of the best wireless earbuds under $50.

Cheap Wireless Earbuds With Strong Battery Life

Duet 50 Pro review

The great thing about the Duet 50 Pro is its outstanding battery life. They provide 8 hours for a single charge and additional playtime up to 122 hours from the charging case. The Back Bay Due 50 Pro are the wireless earbuds are the most battery life as far as I’ve tested. More than Lypertek PurePlay Z7’s 80 hours or Jabra Elite Active 75t’s 28 hours. The Pro models have the most battery life while the slim and standard models provide 30 and 40 hours respectively.

With the strong battery, the charging case can work as a power bank, that can charge another device such as a mobile phone or other devices that use a USB port for charging.

Duet 50 Pro Review – The Sound Quality

The sound quality is quite very great considering the size that is mini wireless earbuds. The bass is much more present and big bass performance. But there is one condition, You have to choose the ear tips size that fit your ears, then they give strong bass and also offer noise isolation very well as well. They provide natural mids and crisp high. The vocals are crisp and clear. Overall the Duet 50 Pro delivers vibrant and great sound. The volume level is pretty loud when compared to other wireless earbuds. The wireless earbuds under $50 are not the best but are still very decent.
