Conclusion: The Sennheiser HD 438 headphones aren’t all that pretty, but certainly pack a punch. The design isn’t to taste at all, so we’d be interested to hear what the new and slightly better-looking HD 428 and HD 448 can produce. Also, if you’re looking for a set that can block all noises or adapt to your on-the-go listening needs, you’d better keep looking.
Pros: Snug, comfortable fit; very good sound quality; has some noise-canceling qualities
Cons: Fragile build; ugly design; no volume controls or other frills
