The only issue I have is the battery life

So far battery life is great

The battery life is good it lasts me like two school days listening to music all day

This is lightweight without losing any of the good sound quality or battery life

The win for me is the battery life

Otherwise, Senso has great customer supports, the earbuds sound is great, battery life is good, and it connects well and very easily, although it takes a couple seconds longer to connect than the over-the-ear-hook ones.

Battery life is sufficient and recharge only takes 30-40 minutes from dead.

Battery life is good.

Above average sound and good (not great) battery life

The battery life is incredible.

They have good range, great battery life (several workouts=4 hours at least), fast easy connection to my iphone 7 and they're comfortable.

The only issue I have with them is the battery life however the quality of the sound is perfect

Everything from the packaging, setup, product design & quality, and battery life has exceeded my expectations.

The battery life is good

My complaint is that the battery life has increasingly gotten worse over time

The battery life sucks, only about 3-4 hours but the sound quality is decent and they are very convenient for the gym.

The sound quality was very good and the battery life was fine

The sound quality is good and the battery life is great

battery life lasts long time till recharge.nicely done Senso! affordable too.

They work great, battery life is great.

They work great, battery life is great.

Over time, though, the battery life began to deteriorate, and now the unit will only hold a charge for a couple of hours at most

The battery life is great and the fit is secure.

The 255s I received don’t sound nearly as good as these 300s and aren’t nearly as comfortable.

The description is misleading as I don't think they are sweat proof
