The Bohm B-66 are above-average wireless Bluetooth headphones that sound great and won't disturb the people around you at high volumes. They're stable enough to not slip off your head easily but feel too tight, which can get uncomfortable. They also poorly isolate listeners from ambient noise in loud environments.

Our Verdict

6.6
Mixed Usage 

Decent performance all round the Bohm B-66 will make good everyday headphones if you like their on-ear design.

Pros
  • Great audio reproduction.
  • Minimal leakage.
  • Stable fit.
Cons
  • Uncomfortable clamping pressure.
  • Poor noise isolation.
7.3
Neutral Sound 

Average for neutral listening. They have a good sound but their closed on-ear design limits their soundstages.

Pros

Cons

    The Bohm Wireless Bluetooth are sleek looking headphones. They have a two-tone black and silver color scheme that looks great feels modern. This, combined with their wireless design, gives them a minimalist aesthetic that's visually appealing. They are also offered in a different color scheme.

    The Bohm B-66 wireless headphones feel too tight on the head. They are moderately well-padded and the ear cups, although small rest well on the ears. Unfortunately, to maintain a stable fit the headband exert an uncomfortable amount of tension on the head. This makes the headphones hard to use for long listening sessions as the pressure can cause soreness and physical fatigue.

    Button layout and functionality is above-average. These headphones provide call/music, track-skipping, and volume controls. The buttons have excellent tactile feedback, but the overlapping functions for volume and track-skipping controls might take some time to get used to.

    The Bohm B-66 are mid-sized on-ear headphones that do not take up much space in a backpack or handbag. Unfortunately, they do not fold up into a compact format, which means they won't fit in a pocket, even large jacket pockets.

    These headphones come with a sturdy hard case that will protect them from scratches and from falls. However, it does add a little bit of volume to the headphones.

    Build Quality

    Build quality is average at best. The Bohm wireless Bluetooth headphones are sturdy enough to handle a few drops without being damaged. Unfortunately, their lightweight design doesn't feel as durable as some other headphones and the swivel mechanism feels loose and susceptible to breaking under physical stress.

    7.5
    Stability

    The Bohm Bluetooth headphones are surprisingly stable on the head. The clamping tightness that may be uncomfortable for some prevents these headphones from slipping off the ears even while running. They're not designed for sports so during high-intensity activities they will move slightly, but they easily maintain their position during casual listening sessions.

    Poor isolation. The passive isolation provided by the ear cups does a good job in the treble range. However, the effectiveness diminishes as the frequency lowers. The active isolation provides a maximum of 10dB of cancellation in the bass range, which is below average and does not do much in the mid and treble ranges.

    Very good leakage. The majority of leakage is in the treble range and the overall level is low. Listening to these headphones at loud volumes shouldn't be an issue in most situations.

    The Bohm B-66 have a battery life that's just below average. Unfortunately, they take surprisingly long to charge, which makes them not ideal for prolonged use. They also can't stream audio and charge at the same time coupled with the lack of an auto-off feature, results, in a poor battery performance overall.
