Review notes: My first impressions of the sound of the Bell'O BDH806 are based on direct comparisons to other headphones - the v-moda M100 and XS, the FAD Pandora VI and IV, the Beyerdynamic T1 and T90, the AKG K812 and K712, and notes that I've accumulated from many prior reviews. I'll describe how I relate to the BDH806 (i.e. my personal tastes and how I use the headphone) only after covering all of the objective issues. I've avoided most low-cost headphones at this point for several reasons, the biggest reason being that the low cost of manufacturing doesn't allow the kind of detailed quality control in driver matching etc. to guarantee that the sound will be exactly the same (or close to it) from sample to sample. A second reason is the approximately 24 work hours required to test the headphone, make a video, process a couple of photos, and write the report - a lot of work if customers purchase the item and it doesn't sound very close to what the review describes. But, while shopping at the local Whole Foods store, I noticed a small headphone rack with the BDH806 and a few other Bell'O models, all of them white except for the BDH806, which is black. The white headphones were marked $39 USD, the BDH806 (the demo, sans box) $29, and since this headphone was a demo they let me buy it for $19. I listened to it for a minute before buying, and thought it had a good basic sound with no discernable distortion. NOTE: This review is aimed at audiophiles with extremely limited budgets, who possess Apple i-devices, and who need the very best sound they can get for $29 or so. All other users should skip the critical analysis of the sound in the next paragraph, and read the technical details that follow. Out of the box, the BDH806 sound is pretty good - in fact, I've had a number of headphones up to the $200 price level that didn't sound any better. Some of those are the ATH ES700 and WS55, Bose OE2 and SoundTrue OE, Klipsch Image One, Marley Liberate XL, Marshall Major and Monitor, and Phiaton MS300 and MS400. The thing that all of those headphones have in common with the BDH806 is a basically good physical quality and drivers, such that applying EQ as I did made the sound very hi-fi with a great soundstage etc. The thing that the BDH806 does not share in common with those other headphones is the low price (the BDH806 MSRP may be higher than $29, but less than $39). Without EQ, the sound is slightly weak in the deeper bass, somewhat distant in the midrange, very recessed in the treble, and with a narrow or 'constricted' soundstage. With EQ, the bass is solid, the mids clear and present, the highs extended and sparkly, and the soundstage and overall sense of "aliveness" is amazing. The BDH806's isolation is modest - possibly less than average for a full-sized closed headphone - OK for me when walking near a busy freeway, but could be a concern on passenger jets or very noisy trains. Leakage is also moderate, and unlikely to be a problem when used on a train, bus, or jet plane, but if used in a public library or a very quiet office, volume would have to be kept below audiophile levels. The BDH806's appearance is very slim on the head, so I don't have any concerns about unseemly looks when used outdoors or on public transit. Both the overall weight and earpad pressure are very light, and I'd judge the BDH806 to be one of the most comfortable headphones I've ever used. This is an ideal portable headphone in the sense that it can be pulled off the head when not in use and worn around the neck with no inconvenience, since the eacups can be pulled down well below the chin and folded flat against the chest. The range of adjustment for different head sizes is only 1/4 inch smaller on each side of the headband compared to my average-size head, but 5/4 inch larger on each side. So the BDH806 will fit head sizes from very slightly smaller than average to quite large. The cable is double-entry, non-detachable, and has a flat-ribbon design that I appreciate. The single-button control box has a mic, and with my iPhone 6-plus that button can start/stop the music, skip to the next track with 2 quick clicks, and skip back to the previous track with 3 quick clicks. The cable doesn't seem to be especially microphonic nor does it tend to stick to my clothing. In previous reviews I've included the following music examples with comments about how the headphones sound with each track. My suggestion is instead of reading each one as an absolute unto itself, you could compare my notes here to those other reviews and see how the BDH806 compares with each individual track. Note that the comments below apply to the BDH806's sound played with the Audioforge equalizer as noted above.
