Sennheiser HD-25 Amperior Review

| May 6, 2012 | 0 Comments

Price: $349 (MSRP $349)
Wear style: On-ear (Closed-back)

In Short: A modified version of the HD-25-1 II which slightly improves the sound quality.

Quick overview:

The original HD-25-1 II is one of the best isolating and best sounding portable headphones at its price of $199. It has been a long-time favorite among DJs and other professionals, especially those who need a snug fit and good isolation from outside noise. Despite being such an old model, it is still a top recommendation even to average consumers.

Instead of the “if it ain’t broke, don’t fix it” approach, Sennheiser couldn’t help themselves. They have made a few changes and have released the 2012 edition, the HD-25 Amperior.

The Amperior is very similar to the original. The biggest difference is the improved ear cups. The original HD-25 has plastic ear cups while the the Amperior uses aluminum ear cups. This is able to improve the sound by dampening the sound more effectively to prevent any unnecessary reverberation throughout the headphone structure, which can be audible at times. The cable has also been changed, as you can see from photo above. The L-plug has been changed to a thick straight plug, but be warned: the new plug does not fit some device cases/shells.

For the average consumer, the HD-25-1 II is a home run purchase. For those who can afford the best-of-the-best, the Amperior is a home run plus a jumping stomp on home plate.
