Campfire Audio - IO (B-Stock)

Package received made be awestruck, calling it a B stock. The box is small per se compact & is in deep blue color, adorned by stars & mountains prints, with brand name stamped in a gold. Blue box contents - There is a greyish brown canvas zipper hard case a quality one (expected leather maroon pouch). Gift opening excitement when the hard case was unzipped, to see the earphones tucked away in the mesh string pouch, further pampered by the awesome (fake) wool liner. Earpieces were put in a single mesh string pouch with separate compartment. Cables connected to earpiece, wound & tagged with 2 Velcro’s. Earpieces are work of an art, its small, light in weight, plated in gleaming Maroon red & gold-plated screws. People will never regret for shelling out those value printed papers for this contraption. The finish is matte/satin but shining. The construction is solid. Accessories in 2 mesh string pouches consist of marshmallow tips, silicon tips, Final E tips, a CA logo lapel pin & a cleaning brush put loosely in the box aong with Final E type tips referring document. Burning - I decide to hear it first before burn in. Some amount of warmness felt inside the ears hearing. Left it to burn in for 2hr the warmness were there. Once again ran it for 2 hrs next day, it was cool to touch & to hear. Out of the box & after burn in; the sound hasn’t changed drastically. For burn in I used the CD player. Wearing - This IEM fits well inside an ear without hurting or hitching & can be worn for long hours. I tried using all the tip options supplied, all were really good, with the Final E tip there was change in bass no major change in sound. When I used the Final E tip I had a pain in the concha area due to the edges of the earphone brushed, reusing earphones after sometime didn’t felt the pain. Cable – it as a smoked grey jacket, super light in weight & thin, one cannot feel its suspended, it is soft to touch & to wound, but there is a minor stiffness. There are no tangling issues for 98% of the time. This cable is so thin which scared me of getting it damaged due to tugs. With this thin cable there are no phonics issues.

Sound to Music - For the first time when this is heard there will be no goose bumps which may be due to lack of bass. It has a unique tuning which will make one enjoy. Soundstage is impressive with width & depth being awesome, height is fair. This has a holographic sound at times. Vocal is pushed to center & bit forward with clean & loudness, which exhibits W shape sound. At times vocal is pushed far back of inside the head (a new experience), this give a U shape sound. This IEM has a bit of nose sounding. Imaging/separation is good but if the track has more mix it gets crowded. Sometimes some instruments are failed to get registered due to the fast nature of the driver & if those are placed low in the track. Bass is tight in bass heavy songs, kick drum are heard clearly, If it doesn’t sounds bassy it feels thumpy, if it is too thumpy then it is annoying. Sub bass is present, the impact is very lean. Treble are lean & peaky or say bright, but not hurting. Highs are smooth, lean and clean. Guitars & string plucks are clearly heard in tracks without much of empathizing. This IEM exhibits a bright & sparky nature of the tweeter BA driver, there is some smear or sibilance are heard based on the song & cannot be toned down, sensitivity of this IEM to be considered. occasionally some more volume is required. Couple of times I heard some creeks/scratch in right earpiece intermittently. To reduce the high ended nature an external DAC/AMP is required. This IEM produces music musically. I found IO is best for string filled songs, good for (Acoustic) POPs & cannot handle songs like EDM, heavy metal, rocks which has more mix or crowded instrument arrangement. Still movie songs sound good if it has a good recording, but the remastered or the old movie tracks like 1 or 2 decades old may not sound great.
