Westone W40
The W40 are decent mixed usage headphones. They have a sturdy, durable design and a stable, comfortable in-ear fit. They also isolate quite well in loud environments and barely leak even at high volumes. This makes them above-average headphones for sports and office use and thanks to their high passive isolation they do well as commuting headphones too. Unfortunately, they have a subpar sound that may disappoint serious listeners.
