6. Little Bear B4-X Portable

Little Bear B4-X Portable Review
  • The difference between B4 and B4-X: ① B4-X is a dual-mono balanced version. Its left and right channel are amplified by independent components, and power supply, tubes, and op amp are all independent and symmetric. So the degree of sound separation is higher than B4.
  • ② B4-X adopts 2 groups of independent power supply(+12V and -12V) for 2 op amps, less mutual effects and can drive 300Ω headphones. ③ The circuit adopts dual op amp parallel output, with higher output power. ④ B4-X has 3.5mm and 2.5mm 2 kinds of output interface, suitable for most of balanced and standard headphones.
  • Mini size and unique design: built-in tube makes you have a tube amplifier which can be held by one hand, convenient to carry and can enjoy HiFi music everywhere. Full, delicate and soft sound: warmer than transistors, independent op amp and power supply inhance the SNR and degree of separation, less interplay and higher sound quality.
  • With built-in battery protection circuit: battery lets your listening feast without time limitation. It can’t be turned on during charging and will power off automatically after fully charged, and charger LED will turn to green.
  • High-end making material and craft: using gold-plated socket, original nichicon electrolytic capacitor, original DALE resistors and precision ring resistance. Prompt and courteous customer service.

Buyer’s Guide for selecting the best amp for Beyerdynamic DT 990 pro

Beyerdynamic’s DT 990 headphones were designed to provide a unique sound signature. They’re polarizing, with either the Edition or Pro models depending on your needs; there are three editions available – 32ohm for home use and 250/600 Ohm if you want them both professional-grade quality but need higher output levels outside of that space as well.

The default version offered is a coiled cable black ear pad grey pads straight audio cable color scheme which looks sharp while still being comfortable enough without hurting my ears at all like some other brands do where their plastic parts dig into me after wearing.

The 990 Pro’s signature is a V-shaped sound, with elevated bass and treble. Connecting your headphones to an amp will help you improve detail in music as well as increase dynamic range by separating sounds better than what the average speaker can do without adding extra volume or distortion from their speakers.

The Beyerdynamic DT990 Pro has been known for producing detailed audio thanks largely due to its great separation skills when paired up correctly, but even if they’re turned off completely – across all frequencies – these cans still manage noise isolation so users don’t have any distractions during long commutes.

When connected wirelessly via Bluetooth 4/5GHz HD Audio transmission technology from compatible devices like laptops & computers as well as smart speakers such as Amazon Alexa enabled ones then these cans will offer even better clarity when streaming music through services including Spotify Premium 

There’s a lot of discussion about whether you need an amp for the Beyerdynamic DT 990 pro. By using an AMP/DAC it will make everything sound better if you do.
