Perceived loudness of Sony CFD-S350 boombox depends on numerous objective and subjective factors. Quality of Sony CFD-S350 boombox’s headphone amplifier and stereo speakers play crucial role in determining how loud the volume Mega Bass boombox is played back at through stereo headphones or out loud during music sharing sessions. Portable audio devices such as MP3 Player, compact disc player, cassette player or boombox feature low-powered headphone amplifiers ranging between 5-15 mW at designated impedance and stereo speakers rated at 2-3 Watts max. RMS output power (at 10% T.H.D.). Headphone amplifiers found in component stereo equipment may be rated up to 500mW at selected impedance. Component stereo receiver’s power amp section may be rated at 200 Watts RMS or more at 8-ohms impedance (at 0.09% T.H.D.) and more powerful than digital stereo power amplifier found in Sony CFD-S350 boombox. Stereo receiver can power stereo headphones with higher impedance rating of 70-300 ohms or greater more efficiently compared to Sony CFD-S350 boombox’s 16-68 ohms stereo headphone amp. Stereo receiver or integrated amplifier makes use of Full-Size .25-inch (6.3mm) Stereo Headphone Jack to deliver increased amplifier power to home theater stereo headphones. Sony CFD-S350 boombox uses a smaller 3.5mm (1/8”) Stereo Headphone Jack that can’t deliver same amount of loudness as Full-Size ¼” Stereo Headphone Jack on component stereo. Headphone driver’s sensitivity rating plays important factor in loudness perception on Sony CFD-S350 boombox. Consumers must purchase stereo headphones rated between 98-117db/mw on driver sensitivity specification to achieve satisfying loudness on Sony CFD-S350 boombox. Sony CFD-S350 boombox’s stereo speakers produce superb Mega Bass loudness in less than favorable operating conditions. Consumers looking for extra loudness to block out external unwanted environmental noise during private listening on Sony CFD-S350 boombox will purchase stereo headphones with better than average sensitivity rating. Higher the sensitivity rating, louder stereo headphones play without need to turn Volume Control up on Sony CFD-S350 boombox. Loudness perception of Sony CFD-S350 boombox is subject to limits of human hearing. Some customers hear sound waves better than others. Hearing levels of Sony customers are not same. Some customers report Sony CFD-S350 boombox doesn’t play loudly enough from stereo speakers or connected stereo headphones. Other customers frustratingly opine Sony CFD-S350 boombox plays too loudly adjusting Volume Controls. Sony CFD-S350 boombox reproduces entire frequency spectrum of human hearing. Sony or third party headphone amplifier can be purchased to augment headphone loudness from Sony CFD-S350 boombox’s 3.5mm Stereo Headphone Jack. Your pick of stereo headphones affects sound properties and loudness experienced during private listening on Sony CFD-S350 boombox. Principles of radio wave propagation, theories of psychoacoustics, laws of physics, Windows Media Player file compression MP3 CD bit rates and recording quality of music listened to determine whether or not there is loud playback from Sony CFD-S350 boombox’s stereo speakers and/or attached stereo headphones. Customers should purchase Sony CFD-S350 boombox to augment perception of loud volumes across music or spoken word entertainment categories on FM/AM bands, cassette and compact disc media. Sony CFD-S350 boombox’s stereo speakers support maximum volume permitted by digital stereo power amplifier. Damage does not occur to stereo speakers if boombox is played back at high volumes. Sony designed boombox drivers to handle all amplifier output power of system. Sony CFD-S350 boombox plays at loud volumes and produces prodigious amounts of well-defined bass through two-channel stereo speakers. Operating instructions indicate sound may become distorted if boombox is played back at excessive volumes. Do not begin playback at high volume to avoid distortion and/or “clipping” of amplifier and speakers. Digital volume level should begin at moderate level and be increased gradually to suit needs and enhance performance and longevity of Sony CFD-S350 boombox. Loudness of boombox speakers depend on amount of amplifier power measured in watts, quality of speakers, type of materials used to make drivers, sensitivity rating of drivers, number of speakers included with boombox and acoustical properties of room Sony CFD-S350 boombox is placed in. Boombox manufacturers do not provide “loudness” specification measured in decibels in operating instructions, marketing specifications or service manuals of portable stereos. Sound pressure level meter from RadioShack must be purchased to get analog or digital readout of sound level when Sony CFD-S350 boombox is playing back music source. Individual results for sound pressure level measurements vary from location to location of portable stereo and volume level of Sony CFD-S350 boombox adjusted up or down. For any boombox sold by Sony, higher the amplifier output rating, perceived loudness and clarity of sound from Sony CFD-S350 boombox is increased. A Sony CFD-S350 boombox rated at 4.6 Watts (RMS at 10% T.H.D.) of discrete amplifier output power plays louder than 2-3 Watt (RMS at 10% T.H.D.) max. rated boombox. A low-powered 2W boombox plays loud enough for small home office or provides suitable volume for background music at dinner party. If you desire boombox that fills home with earthshaking bass and strong vocals for party, purchase Sony CFD-S350 boombox. I recommend purchasing highest wattage Sony boombox available at time in your budget as long as you have right amount of physical space to accommodate placement in room. Sony CFD-S350 boombox offers supreme Mega Bass sound quality, performance, features and value for your money compared to similarly situated competitor boomboxes. Sony CFD-S350 boombox plays music clearly and with supplementary bass at any volume than lower powered competing boomboxes. Benefits to consumers from reducing volume on Sony CFD-S350 boombox include: 1. Sound leakage through stereo headphones is reduced. Customers find this option attractive during private listening indoors or outdoors to avoid annoying people with music they don’t like sitting and standing next to them. 2. Customers hear external sounds in immediate surrounding environment such as traffic noise much better wearing stereo headphones with music playing at same time. 3. Volume attenuation on consistent basis promotes hearing safety for Sony CFD-S350 boombox customers. When volume control is turned up, user winds up blasting loud music directly in his/her eardrums for hours daily. Customer’s hearing health is not protected against irreversible hearing damage from unmitigated, unintended and abrupt changes in volume levels during audio disc, cassette or radio playback. Human hearing adapts easily to excessively loud playback volumes. Because customers become comfortable with loud volumes quickly, they can damage their hearing over time without being cognizant of this fact. Sony CFD-S350 boombox’s volume should be reduced during public or private listening to prevent undesirable hearing loss so Sony keeps customers listening to Sony boomboxes for lifetime.
