| The Bottom Line | At around $50 online, the MEElectronics A151s are among the most affordable balanced-armature earphones out there and deliver very good sound for the money. | The Klipsch Image S4 earphones offer up sound quality on par with and better than sets that cost many times as much; they are a spectacular choice for anyone looking for new earbuds. | Klipsch's ultracomfortable, noise-isolating ear tips are just one of the reasons I love and recommend the S4-series headphones. If you're an Android user shopping for a new pair of earbuds, the Image S4A headphones are definitely worth the $99. | The iSport Immersion headphones rank among the best wired in-ear sports headphone models out there in terms of fit and sound quality. | The Klipsch Image S4i II in-ear headphones add a new, more durable tangle-resistant flat cord while retaining the S4 model's very respectable sound quality and superior comfort. | Basic specs |
