"Not recommended to buy due to very poor Call quality . Cons:1) Call quality - Speaking on phone outdoor in impossible, even the volume is at full."
"Very bad call quality (mostly internet calls)-Delayed notifications or no notifications at all (even for alarms)-Battery life deteriorates very quickly (1 month)"
"But bad voice quality . I purchased this product and is using for last 16 days."
"The voice clarity is superb and sound reproduction is a treat. The call quality really stands out."
