Short answer: buy the Neumann TLM 103 Mono Set if you record vocals, voiceover or acoustic instruments in cardioid and want the quietest microphone of the three. Buy the TLM 107 Studio Set if one microphone has to cover vocals, drums, guitar amps and stereo work. Buy the U 87 Ai Studio Set if you want the classic studio sound that has been on records since 1967 and the budget allows it.
All three are large diaphragm condensers that need 48 V phantom power, and all three cover 20 Hz to 20 kHz. The real differences are polar patterns, self noise, how loud a source each one can take, and price. The TLM 103 is fixed cardioid with 7 dB-A self noise. The TLM 107 has five patterns and handles up to 153 dB SPL with its pad. The U 87 Ai has three patterns and a transformer balanced output.
This guide compares the specifications from Neumann's own product pages, explains what they mean in a real room, sorts out the mono set, studio set and stereo set listings, and gives prices as listed on proaudiobrands.com in September 2026.

What the numbers mean in practice
Self noise: how quiet is the microphone itself
Self noise is the hiss a microphone produces with no sound in front of it. Lower is better. The TLM 103 is rated at 7 dB-A, the TLM 107 at 10 dB-A, and the U 87 Ai at 12 dB-A in cardioid (14 dB-A in figure-8 and 15 dB-A in omni). On a loud rock vocal none of these numbers matter. On a whispered voiceover, a fingerpicked guitar or a microphone placed a metre back from a tanpura, the TLM 103's lower noise floor is audible once the recording is compressed and turned up.
In most Indian home studios the room is noisier than any of these microphones. A ceiling fan, an AC compressor outside the window or traffic will sit well above 7 dB-A. Treat the room and switch off the fan before worrying about a 3 dB difference in self noise.
Maximum SPL: how loud a source can get
Maximum SPL is the loudest sound the microphone electronics can handle before distortion reaches the rated figure, here 0.5 percent THD. The TLM 103 reaches 138 dB with no pad. The TLM 107 reaches 141 dB with no pad, 147 dB at -6 dB and 153 dB at -12 dB. The U 87 Ai is rated 117 dB, or 127 dB with its pre-attenuation switch.
A singer at normal distance is nowhere near any of these limits. A kick drum, a snare close-miked, a brass section or a guitar cabinet at full volume is where they matter. The TLM 107 is the one to put in front of the loudest sources. The U 87 Ai is fine for vocals and most instruments, and needs its pad engaged for very loud close work.
Sensitivity: how much signal reaches your preamp
Sensitivity tells you how much output the microphone gives for a given sound level. The U 87 Ai gives 28 mV/Pa in cardioid, the TLM 103 gives 23 mV/Pa, and the TLM 107 gives 11 mV/Pa. In practice the TLM 107 needs roughly 6 to 8 dB more preamp gain than the other two for the same source. Any decent audio interface has enough gain for a condenser on vocals, but on a quiet spoken-word source a cleaner, quieter preamp helps the TLM 107 more than the TLM 103. If you are still choosing an interface, our audio interface buying guide covers the preamp side.
Neumann TLM 103: the quiet cardioid specialist
The TLM 103 uses a large diaphragm capsule that Neumann describes as derived from the U 87, with a wide presence boost above 5 kHz. That lift is why it sounds forward and clear on vocals, and why vocals recorded on it tend to sit on top of a mix without much EQ. It is transformerless, which Neumann says keeps the sound immediate and uncoloured.
It has no switches at all: no pad, no low cut, no pattern selector. Cardioid only. For a singer, a voiceover artist or a podcaster that is rarely a limitation, because cardioid is the pattern most studio vocals are recorded in anyway. Neumann also lists it for solo instruments, guitar amplifiers, percussion, and as a spot microphone for cello and double bass in classical recording.
Key specifications from Neumann: cardioid, 20 Hz to 20 kHz, 23 mV/Pa, 7 dB-A self noise, 87 dB-A signal-to-noise ratio, 138 dB maximum SPL, 131 dB dynamic range, 3 mA current draw on P48, 60 mm diameter, 132 mm long, about 450 g.
Choose the TLM 103 if you record mainly one voice or one instrument at a time in cardioid, and you want the lowest noise floor in this comparison.
Neumann TLM 107: five patterns and the highest headroom
The TLM 107 is the most flexible of the three. Neumann built it around a newly developed dual diaphragm capsule and transformerless circuitry. It offers five polar patterns: omni, wide cardioid, cardioid, hypercardioid and figure-8. A single navigation toggle on the back sets the pattern, the pad (0, -6 or -12 dB) and the low cut (linear, 40 Hz or 100 Hz), with LEDs showing the current setting.
What those patterns do in practice:
- Omni picks up evenly all round. Useful for a group of singers around one microphone, or for room sound in a good-sounding space.
- Wide cardioid sits between omni and cardioid. It gives a more open sound with less proximity bass than cardioid when a singer works close.
- Cardioid is the standard vocal pattern, rejecting sound from behind.
- Hypercardioid is tighter at the sides, handy for reducing spill from a nearby drum kit or a second instrument in the same room.
- Figure-8 picks up front and back, rejects the sides, and is needed for mid-side and Blumlein stereo techniques.
Neumann lists it for acoustic and electric guitar, piano, upright bass, drums and percussion as well as vocals. Key specifications: 20 Hz to 20 kHz, 11 mV/Pa, 10 dB-A self noise, 141 dB maximum SPL (147 dB and 153 dB with the pad), 131 dB dynamic range, 3.2 mA on P48, 64 mm diameter, 145 mm long, 445 g.
Choose the TLM 107 if you run a project studio that records a different source every day, or you want one expensive microphone that can also go in front of drums and amps.
Neumann U 87 Ai: the reference studio microphone
The U 87 Ai was introduced in 1967 and uses the same dual diaphragm capsule design as the U 67 before it. Unlike the two TLM models it has a transformer balanced output, which Neumann pairs with a FET circuit. Neumann describes its on-axis response as remarkably flat while still having character, and calls it the standard microphone for speech and vocals, including voiceover, dubbing and audiobooks.
It has three patterns (omni, cardioid and figure-8) plus switchable pad and low cut. Figures change with pattern:
| Pattern | Sensitivity | Self noise | Max SPL | Max SPL with pad |
|---|---|---|---|---|
| Omni | 20 mV/Pa | 15 dB-A | 117 dB | 127 dB |
| Cardioid | 28 mV/Pa | 12 dB-A | 117 dB | 127 dB |
| Figure-8 | 22 mV/Pa | 14 dB-A | 117 dB | 127 dB |
On paper the U 87 Ai is noisier than the TLM 103 and handles less level than either TLM model. People do not buy it for the numbers. They buy it because it is the microphone many engineers, dubbing studios and radio stations already know, so a vocal recorded on it sounds familiar to the person mixing it. It weighs 500 g and measures 56 mm by 200 mm, so it needs a solid stand.
Choose the U 87 Ai if you run a commercial vocal, dubbing or voiceover room where clients ask for it by name, or you want the classic Neumann character with the option of omni and figure-8.
Mono set, studio set, stereo set: what is actually in the box
The set names confuse many buyers, and Neumann uses them differently for each model. Here is what Neumann's own product pages list:
- TLM 103 (microphone): microphone, SG 2 swivel mount and wooden box.
- TLM 103 Mono Set: one microphone, EA 1 shock mount and aluminium case.
- TLM 103 Studio Set: one microphone and EA 1 shock mount. We list it as the TLM 103 NI Studio Set at ₹109,900.
- TLM 103 Stereo Set: two microphones, two EA 1 shock mounts and an aluminium case. Listed as the TLM 103 Stereo Set at ₹236,900.
- TLM 107 (microphone): microphone, SG 2 swivel mount and wooden box.
- TLM 107 Studio Set: microphone and EA 4 shock mount.
- U 87 Ai Studio Set: microphone, EA 87 shock mount and wooden box.
- U 87 Ai Stereo Set: two microphones, two EA 87 shock mounts, two dust covers and an aluminium case. Listed as the U 87 Ai Stereo Set at ₹619,900.
The practical advice: get a set with the elastic shock mount. The SG 2 swivel mount clamps the microphone rigidly, so footsteps, a desk knock or building vibration travel up the stand into the capsule. With a microphone as quiet as the TLM 103, that rumble becomes the loudest noise on the recording. As listed on proaudiobrands.com in September 2026, the TLM 103 Mono Set costs slightly less than the bare microphone, so there is no reason to skip the shock mount. Stereo sets only make sense if you record stereo pairs: piano, drum overheads, choirs or room sound.
Buying in India: power, humidity and service
- Phantom power: all three need P48, 48 V plus or minus 4 V. Neumann rates current draw at 3 mA for the TLM 103, 3.2 mA for the TLM 107 and 0.8 mA for the U 87 Ai. Any interface or mixer with proper 48 V phantom power runs them.
- Mains quality: the microphone runs from the interface, but the interface, computer and monitors run from the wall. Voltage dips and spikes during load shedding or when a lift or AC starts are common in Indian buildings. A UPS or a good stabiliser for the whole recording chain protects the gear and stops clicks and dropouts mid-take.
- Humidity: condenser capsules do not like moisture. During the monsoon and in coastal cities, keep the microphone in its box or case with silica gel when not in use, let it warm up to room temperature before recording if it has been in an air-conditioned room, and use a pop filter so breath does not reach the capsule.
- Warranty and service: buy through an authorised Neumann dealer so warranty claims and service go through the proper channel. A microphone at this price is a long-term purchase, and a clean service history also helps resale.
Other Neumann studio microphones to consider
If none of the three fits, Neumann's range has neighbours on either side:
- TLM 102 Studio Set at ₹62,990: cardioid, 12 dB-A self noise, 144 dB maximum SPL, about 210 g, supplied with the EA 4 shock mount. The entry to Neumann. Read our TLM 102 review and the Rode NT1-A vs TLM 102 comparison.
- TLM 193 at ₹134,900: cardioid only, using the edge-terminated K 89 capsule, 18 mV/Pa, 10 dB-A self noise, 140 dB maximum SPL. Neumann describes it as a cardioid-only version of the TLM 170 R, with a very linear response on and off axis. A more neutral alternative to the TLM 103.
- TLM 67 at ₹199,900: omni, cardioid and figure-8, using the K 67 capsule from the U 67, 11 dB-A self noise in cardioid.
- TLM 49 at ₹135,900 and U 47 fet at ₹354,900 for buyers chasing a vintage-style character rather than a neutral capture.

FAQ
What is the Neumann TLM 103 price in India?
As listed on proaudiobrands.com in September 2026, the TLM 103 microphone is ₹109,990, the TLM 103 Mono Set with EA 1 shock mount is ₹109,900, and the TLM 103 Stereo Set with two microphones is ₹236,900. The Mono Set is the better buy because it includes the shock mount.
Is the TLM 103 better than the U 87 Ai?
It depends on what you mean by better. The TLM 103 has lower self noise (7 dB-A against 12 dB-A in cardioid) and a higher maximum SPL (138 dB against 117 dB), and costs far less. The U 87 Ai has three polar patterns, a pad and low cut, and the transformer balanced sound that many engineers prefer on voice. For a single-voice home studio the TLM 103 is the practical choice.
Neumann TLM 107 vs TLM 103: which is better for vocals?
Both are excellent on vocals. The TLM 103 is quieter and has a presence boost above 5 kHz that makes voices sound forward. The TLM 107 adds wide cardioid and hypercardioid patterns, a pad and a low cut, so it adapts better to different singers and rooms. If you only record vocals in cardioid, the TLM 103 is enough.
Is the Neumann U87 worth the price for a home studio?
For most home studios, no. Room acoustics, preamp and performance make a bigger difference than the step from a TLM 103 to a U 87 Ai. The U 87 Ai earns its price in commercial rooms where clients expect it, and where its three patterns get used.
Does the Neumann TLM 103 need phantom power?
Yes. The TLM 103, TLM 107 and U 87 Ai all need 48 V phantom power (P48). Neumann rates the TLM 103 at 3 mA current draw. Any audio interface or mixer with a 48 V switch on its microphone inputs will power it.
What is the difference between the Neumann mono set and studio set?
For the TLM 103, Neumann lists the Mono Set as one microphone with the EA 1 shock mount in an aluminium case, and the Studio Set as one microphone with the EA 1 shock mount. The plain microphone comes with the rigid SG 2 swivel mount and a wooden box instead. For the TLM 107 and U 87 Ai, the Studio Set adds the EA 4 and EA 87 shock mounts respectively.
Can the TLM 107 record drums and guitar amps?
Yes. With no pad it handles 141 dB SPL, and with the -12 dB pad it reaches 153 dB. Neumann lists drums, percussion and electric guitar among its applications, and hypercardioid helps reduce spill from other instruments.
