According to Mayflower's website, the CMOY portable was designed in accordance with many of the audio philosophies used in the Objective 2. The CMOY portable uses the same 4556 OP-amp found in the Objective 2, an OP-amp that is designed for driving headphones and also has the added benefit of not draining too much power for a portable device. The CMOY is equipped with a 280mAh battery which allows for 8 to 10 hours of battery life off of a single charge. Using 32 and 64 Ohm impedance headphones, I verified the 8 to 10 hour battery life claim in testing, typically averaging around nine hours of playtime before a recharge was required (at sustained loud volume levels).
In short, it is ultimately up to you to decide if a portable amplifier is worth it for your specific listening needs and for the headphones that you plan on using with the amplifier. I can however certify that the CMOY portable does everything a portable amplifier should, increase the overall quality of the sound being sent to your headphones and providing a substantial power boost over the standard output of your mobile device. The CMOY portable is built as solid as they come, and is a simplistic and full-proof way to get a better and more powerful sound out of your mobile device.
