| 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 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. | With a sleek design, a range of ear tips, and supreme sound reproduction, the Ultimate Ears 700 headphones are worthy of an audiophile's ear and earn our recommendation. | Basic specs | |
