These outperform Sonys stock foam tips in every way.
Better isolation and bass response, more durable and very secure for gym sessions or runs.
All with the added benefit of mesh layer built into the tips to protect the earbuds.
They also fit in the charging case perfectly.
very good product, worth the buy
Very pleased with fit, excellent fast delivery
Great fitting foam earbud tips. Looks like they will last a bit
Noise cancelling is affected, but it's more comfortable than the default ear tips on the WF 1000XM4s. I'd recommend but, it needs more noise cancelling.
