Youtube review: Senta Forty Wood Earcup Stereo Headphone review by Dale - YouTube Photo: http://dalethorn.com/Photos/Panasonic_Zs40/Headphone_Senta_Forty_01.jpg Sources: iPhone5 with PA2V2/FiiO E07k/Decware Zen Head amps using the LOD, various computers using the Microstreamer/Beyer A200p/v-moda Verza DAC/amps. Review notes: My first impressions of the sound of the Senta40 are based on direct comparisons to other headphones - the v-moda M80 and M100, the Beyerdynamic DT1350 and T51p, the FAD Pandora IV and VI, and notes I've accumulated from many prior reviews. I describe how I relate to the Senta40 (i.e. my personal tastes and how I use the headphone) only after covering all of the objective issues. NOTE: If you're opposed to using EQ with headphones, this review is not for you, since it is based entirely on equalizing the Senta40 to obtain a near-hi-fi sound. Photos and an EQ chart are at the links here, or on my dalethorn site. My first impression of the Senta40 is muffled sound. An emphasized bass alone, or a slightly recessed treble alone might be workable, but the combination of those two issues reduces the clarity and details, and most importantly the proper musical tonality, to the point that there is no longer an authentic musical experience. The Senta Forty's originator (C Crane) is in the business of selling radios mostly, and reading some of those reviews I noted that users occasionally complained that the stereo FM reproduction was substandard. Using the Senta40 with those radios, their impressions would be understandable. In any case, there would be no point in reviewing a muffled headphone unless I could fix the sound somehow, and the Audioforge Parametric Equalizer I use now does that. Since this review is EQ-dependent, all of the following comments including the music track impressions here are based on my Senta40 EQ settings. Some concerns I have with low-cost/low-fi headphones are inconsistencies in matching the sound between the left and right drivers, and matching the sound between different production samples of the same headphone. When there are inconsistencies, a customer may experience a very different sound than what they were expecting based on reviews they've read. Also when using large amounts of EQ to restore a near-hi-fi sound quality (if that's actually possible), there's a danger of creating large narrow peaks and recesses at frequencies adjacent to the EQ sliders. With Audioforge, I've become confident that the correction curves it generates are smooth enough to minimize those and other related issues. There are cases where I finish an EQ and the headphone still doesn't sound right, so I start over from scratch. In most cases the second or third attempt is successful - if not I just give up and try another headphone. The Senta40 is mostly plastic except for the wood earcups and a thin metal reinforcing strip in the headband. The finish looks good and the on-ear fit is comfortable due to soft earpads and the light headband clamp. Earcup rotation is 90 degrees one direction and 45 degrees the other direction. Vertical rotation is 180 degrees, so from the earcup rotations I'd expect the Senta40 to fit nearly any head. However, my average-size head fits with the earcups pulled out just 9 mm, and the maximum extension is just 21 mm, so the range of head sizes that this headphone can accomodate is going to be limited. The cable is double-entry, detachable, with 2.5 mm mono plugs going into each earcup, and terminated by a standard 3.5 mm miniplug with no controls or microphone. The cable has a very nice fabric covering and looks very durable. The earpads are covered in a quality plastic or pleather, which feels comfortable and should last a long time. A 6.35 mm adapter and a soft zippered fabric carry case are included. The comments in the music tracks listed in this review can be compared to other headphone reviews I've done, to get an idea of how the Senta40 plays the different music tracks listed here compared to other headphones. My suggestion is instead of reading each comment below as an absolute unto itself, you could compare these notes to other reviews as they get posted, and see how the Senta40 compares with each individual track.
