Common Customer Complaints
Sellyze identified 10 distinct pain points from customer reviews. The 6 most prevalent issues are listed below.
1. Microphone Performance
Product Defect · Critical · 3.4% of buyers
Microphone picks up background noise more than the user's voice, making phone calls difficult and requiring users to repeat themselves.
"Making phone calls is miserable, I'm heard only sometimes"
"It seems like it picks up the background better than my voice somehow"
2. Pairing Reliability
Product Defect · Critical · 6.8% of buyers
Earbuds frequently fail to pair or lose pairing, causing frustration and repeated returns.
"I've literally gone through 3 diff raycon buds due to pairing issues, yes THREE PAIRS"
"At first they would not pair up in my iPhone"
3. Fit Security
Usability Issue · Critical · 6.8% of buyers
Earbuds shift or feel loose during movement, making them unsuitable for exercise or active use.
"I wouldn't even try to exercise with them on"
"They shift somewhat easily while I'm at work, bending and moving my body around"
4. Missing Features
Missing Feature · Critical · 3.4% of buyers
Product lacks a 'find my earbuds' feature, making it difficult to locate lost earbuds.
"To bad they don't have the 'find my earbuds' feature"
5. Charging Case Feedback
Missing Feature · Critical · 3.4% of buyers
Charging case does not display charge percentage, making it hard to determine remaining battery life.
"It's hard to determine battery life because the charging unit doesn't have a charge percentage display"
6. Noise Isolation
Missing Feature · Minor
Earbuds do not provide total noise isolation, allowing background noise to interfere in loud environments.
"You're not going to get total noise isolation. So, if you're in a super loud environment or want full immersion, you'll still hear some background noise"
