Every link in the chain can change the way music sounds.Д«luetooth technology itself has come a long way.

With wired connections, going through a headphone jack, USB, or lightning connector can also affect the sound as can variations in digital-to-analog converters, which turn the digital data on a phone or computer into an analog signal that can be heard through headphones or speakers. вЂњIf the file youвЂ™re playing is not a high-quality file, or even just not a well-recorded song, then youвЂ™re also at the mercy of that.вЂќ Different headphones or speakers offer different levels of sound quality. вЂњThere are so many moving parts,вЂќ says Brian Lickel, who works in sales at Needle Doctor, a Minnesota-based audio store that specializes in turntables. вЂњYou couldnвЂ™t hear the best quality even if you had it in most of the situations where youвЂ™re listening to audio over Bluetooth,вЂќ Sound UnitedвЂ™s Greco adds.ДЄnd yet вЂњto Bluetooth or not to BluetoothвЂќ isnвЂ™t the only quandary facing listeners concerned about audio quality, of course. The gym, the car, the subway, a busy street, a packed day at the beach-each adds a high level of ambient noise. вЂњMore importantly,вЂќ he says, вЂњcustomers are purchasing multiple pairs of headphones to accommodate different use cases.вЂќ So you might listen to one set of headphones while working out, and another on a long flight.Д«ut hereвЂ™s the thing: In the types of places where wireless headphones would be most useful, a higher resolution level might not even be noticeable.

That said, the amount of music lovers whose daily listening occurs via the kinds of stereo set-ups that populate high-end audio stores is fairly small.

I have cars where you can plug in the music, or go through Bluetooth, and Bluetooth just sounds so flat for the same music.вЂќ From the tech press to alt-weeklies, qualms about Bluetooth audio quality seem to be hardening into conventional wisdom. вЂњI would not use Bluetooth,вЂќ Apple co-founder Steve Wozniak declared in August. The ascendance of Bluetooth for music, though, has drawn criticism. The clever old king has extended his rule.

In fact, Bluetooth headphone sales recently overtook non-Bluetooth for the first time, according to market research firm NPD Group. But Bluetooth audio is hardly just the concern of Apple users. The issue was brought to a head in early September, when Apple announced it would be doing away with the traditional headphone jack in the iPhone 7 and releasing new wireless headphones called AirPods, which are powered by Bluetooth technology and boosted by an Apple-formulated W1 chip. To listen on Bluetooth or not to listen on Bluetooth? That, if youвЂ™ll forgive the obvious reference, is the question that many music fans have been asking lately.
